At what distance should the gasholder be installed. How to correctly determine the distance from gasholdera to a house: choose a suitable location on the site

It's no secret that any procedure involving the preparation of any documents, the receipt of certificates or permits, can rest against a bunch of bureaucratic problems. What awaits you when connecting a private house to a gas pipeline? How to speed up all processes? Let's study all the pitfalls of this procedure together!

1

Needless to say, most of the owners of country houses are interested in gas laying, first of all, for heating in the autumn-winter period. According to statistics, 70% of heating equipment buyers stop their choice on a gas boiler, while the remaining 30% are forced to settle for boilers on electricity or solid fuel largely because the house is built far from gas main.

Fortunately for many, today there are also universal units for sale, which can be used as a solid fuel or electric boiler first, and then, having slightly altered the internal structure (strictly according to the instructions!), Connect the boiler to the gas.

The advantages of gas heating are, as they say, on the surface:

• coal, firewood and other solid fuels require huge storage areas, whereas gas does not actually take up any space on your site;
• solid fuel boilers require the construction of special household rooms (boiler rooms), and when connecting gas, this is not required;
• gas in the house is a solution to both heating problems and hot water supply problems;
• with gas in the house you can even heat the garage and other utility rooms;
• when selling a house availability gas heating   plays a big role in pricing - the cost of a house is growing significantly!

The majority understands by gas supply only the connection to the gas pipeline main. However, there are other ways to provide a home with this useful resource. The simplest of them is the use of liquefied gas in cylinders. In many settlements there is an organized delivery and replacement of cylinders, many traditional gas stations are now equipped with gas filling stations. However, the cylinders are suitable only for cooking, for heating big house   this method remains very expensive - now and then you will have to visit a gas station with empty tanks.

2

And what if the balloon is made very large, to fill up had to be every few years! Before that, they already thought of it for a long time, and this gas tank is called. This is a very capacious horizontal tank, where a gas reserve of 2-5 thousand liters is pumped in. For a house with a heated area of ​​100-250 m 2 gasholder will have to be refilled every six months or a year. Usually, the fuel is carried out before the heating season, because in summer the fuel costs are significantly reduced.

In general, this method allows you to recoup the initial costs for 5-10 years, since gas for gas holders companies that provide installation and maintenance of gas supply, usually released at lower prices. And what is most interesting - if you organize everything correctly, purchase the necessary equipment, a boiler and, in fact, the gas holder itself, after 3-4 days your house will be with gas. How is this possible? As a rule, companies that manufacture or sell gasholders, take on all the technical documentation and clearance in the relevant authorities.

Such a pleasure is not cheap - an average of 150 000 rubles. Earlier, in some cases, the connection to the gas main was not cheaper, but from March 2014 in the Russian Federation laws were adopted that simplified and reduced the cost of connecting private traders with small volumes of gas consumption. Now the cost of the connection itself can cost up to 50 thousand rubles, or half as much - it all depends on the distance between the site and the gas pipeline.

For example, if your house is located at a distance of no more than 200 meters from the main pipe and the gas consumption per hour will not exceed 5 cubic meters (enough for heating a house with an area of ​​250 square meters), then for connection you will have to pay about 30 thousand rubles . The law describes the process in detail and does not allow for any discrepancies. True, the registration of documents and all permits takes several months, so do not postpone this question until winter, if you intend to move to a private house   for permanent residence.

Let's start with the main thing - laying the pipe is feasible only to an existing house. The law forbids bringing gas to an empty site, even if you plan here in a month. However, the room does not have to be already inhabited - if the walls and the roof are built, you have the full right to insert into the main pipe. Prepare a package of documents, namely:

1. Documents for ownership of the site.
2. Technical passport of the house.
3. Certificate of ownership of the house.
4. The cadastral plan.

About the presence of a passport and identification code you hardly need to be reminded - these documents are needed everywhere. The farther the house is from the distribution gas pipeline, the more costs there will be - the pile of the distribution pipeline will fly in a pretty penny, and you will have to negotiate with neighbors who must give permission for laying pipes along the territory of their plots. Such permits must be notarized!

If the rooms in your house have standard height   ceilings 2,5-2,7 m, the house is qualitatively insulated, and modern double-glazed windows are installed, the calculation of the heat load can be made independently, starting from the quadrature of the heated premises - by 10 sq.m. 1 kW of heat energy is required. If the project of your house is replete with high non-standard ceilings, wide panes on the whole wall, you intend to heat a winter garden and a glazed veranda, then it is better to contact a specialized organization for the correct calculation of the capacity of the heating equipment. Information about the heat load will also be needed when preparing documents for gasification of the house, choosing a boiler and radiators.

Specifications for gasification - a document with the above requirements of the gas service, without observing which gasification is impossible. You can get the technical information in the local gas service, having the technical passport for the house, as well as the documents confirming your identity and the original TIN. Come to the gas service, write an application for TU, fill in a questionnaire (location of heating equipment, brand and capacity, heated area, etc.), pay for the development of technical conditions and start waiting.

Wait for a minimum of a week - by law, the receipt of technical specifications can last up to 14 working days. However, for various reasons this procedure can stretch for a whole month.

Technical conditions are necessary for the design of the gas pipeline, which is ordered in special design organizations. Many companies provide such services today, many combine design and installation works - together these services will cost 15-20% less. It is important to select really experienced specialists who will perform their duties promptly and qualitatively. The company must have a license for such work.

In addition to the specifications, you will also need a topographic survey of the site with the designated engineering communications, which must be assured in the local gas service. Such a document can be ordered from design institutes or from individuals who have the appropriate equipment and skills. With you, you should have a copy of the home certificate and a certificate of inspection of chimneys for compliance.

If you intend to use imported gas equipment, you will need to prepare certificates that confirm its compliance with the requirements and norms established by law. Also, a positive conclusion of experts on the possibility of using this equipment in our country is needed. As a rule, these documents should be offered to you even at purchase, so it is important to purchase heating equipment through certified representatives of the manufacturer.

After the conclusion of the contract with the project organization, a design engineer must go to your site to perform all measurements and make a plan indicating the boiler room, the location of the heating equipment and its capacity. At this stage, the customer of the works must coordinate the project with all the institutions whose interests affect the gas pipeline to your home (electricity, water, autodor, etc.). Of course, for some money this can be handled by the office in which you ordered the project.

The project, after all approvals, goes to the local gas service for approval. Usually it takes about two weeks. Be prepared for the fact that the project will be sent for revision, indicating the list of comments, after correction of which it will finally be agreed.

5

If you have not decided on the installation organization at the time of drafting, it's time to do it. The customer signs an agreement with the contractor, in which the terms of the performed works, their list and cost of services are clearly stipulated. The contract should also specify the work on testing the finished gas pipeline. The testing organization must conduct the tests, but it is better to be reinsured by the contract.

After the test works, the executive and technical documentation is prepared, which is given to the customer for approval. The payment is made after the completion of all works and the acceptance of the gas pipeline by the local gas service in operation! The gas service must draw up a commission from its own representative, contractor and customer. The commission at the facility checks the work and equipment. This procedure takes from 14 to 30 calendar days.

If representatives of the gas service and other regulatory bodies have no comments, a receipt of technical supervision is issued, the paid copy of which must be transferred to the installation organization. The installers prepare the technical documentation and transfer it to the gas service, after which the gas meter must be filled with gas meters within two weeks, and a gas use agreement is signed. The homeowner will need to be instructed on the safety rules - the features of the operation of equipment and the gas pipeline must be taught in the gas service.

At this stage, it is already possible to pay on the accounts of the service that performed the sidebar in the main gas pipeline. After payment, the gas service has all the grounds for launching the gas. Please note that this service is chargeable. After the gas start-up, the specialists of the organization that provides the gas equipment service should check the gas boiler and put it into operation. In this case, the optimum operating mode is established. The owners of the house should be explained in detail how to use gas equipment, how to operate in emergency situations. After the inspection and instruction of the parties, a two-sided certificate of the executed works is signed.

According to the law, if your settlement is included in the list of facilities subject to gasification, the gas pipeline to your house should be free of charge. Alas, in practice, this happens rarely - the owners have to wait years until the funds for the gas pipeline are allocated, so the majority conducts gas through family budget. Try to persuade neighbors to connect to gas at the same time - in this case, the work will cost significantly less to you and neighbors.

Do not miss the chance to get hold of the coveted connection and in the event that the gas is conducted on a nearby street. If there is no gas pipe in your village at all, not everything is lost - if there is a highway in the neighboring village, you can also gas to you. However, there will be much more trouble in this case - those wishing to use natural gas will have to organize themselves in a public organization and poke the thresholds of gas workers so that they can equip your gas regulating station in your settlement.

As for tariffs for connection to the gas main, they can be divided into standard and elevated. Standard tariffs apply only when the distance from the house to the gas pipeline is 10 meters for the city and 25 meters for houses outside the city. In these cases, the total amount spent will depend on the type of terrain, the method of laying the pipe and the size of the meter.

In all other cases, all the factors listed above are supplemented with soil quality, terrain relief, and the shape of the building. Taking into account all the aggravating factors, the real cost of connection to the gas pipe can amount to 3 and 6 thousand conventional units.

   House 200 m. Place real, this is 10 by 10 in two floors, if with the base total less than 10 to 10. On the plot of 6 hundred. it will have to be placed in one of the corners of the site. Another corner without problems is a small bathhouse 6 for 4 for example, there will be a place on the pergola and for a carport under the auto + hoz.blog. There are fruit bushes along the fence and not many trees. On different sides of the septic tank / well. On the grass there is enough space, if you keep the purity, then everything can be done beautifully and correctly, but understanding must be done right away. It is necessary to "observe" the norms of distances to neighboring buildings.
  SNT all are different are strong and united, there is SNT where our grandparents and grandfathers with the same type of houses with high roofs or a broken attic, drooping fences and blackened houses with old houses sit still, and since SNTs are collective decisions, they can be persuaded to improve them , which require fin. investment is sometimes very difficult. But it also happens that SNT is already inhabited by the children of those same grandmothers and grandfathers, and then the SNT changes and blossoms, at the entrance there are flowers and a vending machine. The gate, gas and, in general, landscaping of the whole territory.

SNT as a rule many without gas or wiring it requires fin. investments by the collective of SNT, plus some discomfort in the form of dug up roads and roadsides. The more in the SNT residents "year-rounds" the greater the chance of gas. If it is not enough, the grandmothers and grandfathers in any will not agree not that what to enclose means, they will be against a digging of roads and roadsides.
  What then to heat? Either the electric boiler Zhenya, or combined (ie electric + wood, coal, etc.), you can also use a pellet machine, or smelly diesel. Here the choice is yours. You can also do a little easier to lay down the brick oven with access to the main rooms and hang up the electric radiators in the rooms.
  I will say at once on one electric boiler with the wiring of batteries around the house will not go far. In the first SNT this restriction on dressing up, if "10" is allocated on a site means be pleased, and happens that there is a general, ie. in the summer when the SNT is full, you will not have much stress in the house, and it will be missed ... a dim light and other things are secured. The installation of a more powerful transformer grandparents do not want to fold.
  Gazgolder at 6-hectare do not break, this is a violation.
  SNT payment of electricity either as everywhere, there prices are different day around 6 rubles. night 1 with a penny. Since you're a young woman, the increased consumption and the concept of saving is clearly not for you. The bill for light is planned in winter at least 10,000 per month.
  The house is only a frame with the correct "pie" and sufficient insulation (floor 20 cm, walls at least 15, ceiling 20-25 + good windows)
  Also, SNT is an independent garbage collection, cleaning is expensive in winter so it is very important how much you will live there in the winter.
SNT you are deprived of the presence of a district doctor for children, only by agreement they come on call.
  Ideally, the site is not surrounded by neighbors, for example, extreme, i.e. the fewer neighbors the better for very much all nearby and fans will look at your boobs very much))).
  In general, here is not much introductory, though skomkano but as it is.
  SNT ... pay attention ... the qualitative and quantitative composition of its population in the winter and summer period, electricity capacity and prosperity + cost, availability of nearby infrastructure.
  6 cells is enough to live qualitatively, but not much to do ...

It would seem that a naive question, but in fact, only when you know what kind of animal this is - a gas holder and whether it is necessary for us as ordinary citizens. On the Internet, they write a lot about them, argue that it's better and cheaper, which one to choose, but that's just what a gas holder says in Russian forget. And this is just a capacity or if you want storage tank for liquefied gas   - propane - butane.

Gazdolder - the internal device.

Now it is clear, if you have decided to heat a dacha with liquefied gas   You can not do without gasholdera. The gas holder can be cylindrical or spherical, underground or aboveground, but in any case if you decide to heat liquefied gas you can not do without it. So before you buy it and install it, you should learn the rules of installing a gas holder on the site.

Underground gasholders are certainly more profitable, in the earth even in winter it is warm, so the gas from the liquid will easily, without additional costs for evaporation, turn into gas as we imagine it, just give it a way out.

Volume of gasholder   it is worth choosing, having calculated the necessary reserve of liquefied gas for the heating season, approximately 4.5-6.0 liters are expended per 1 m2 of heated area per month (this is for the Rostov region). Serially gasholders are produced in volume from one to ten cubic meters - for cottages and private plots and from twenty to fifty cubic meters for cottage settlements or industrial facilities.

How to properly install gasholder in the suburban area.

Immediately make a reservation erect gasholder   it is possible only under the project coordinated with the local gas supply organization and Rostechnadzor, and the installation should be conducted only to legal entities that have permission to do so - SRO.

But before starting it's not a bad idea to plan the territory itself, but you can install a gas-holder in accordance with the requirements specified in point 8.1.6   SNiP 42-01-2002 "Gas distribution systems". This SNIP applies to the installation of gas tanks up to 50 m 3.

Now all about the necessary distances for installing the gasholder in the country.

Distances from the apartment house to the gas holder.

Overhead gas holders

- over 5m 3 to 10m 3. - 30 meters;

- over 10m 3 and up to 20m 3 - 40 meters.

Underground gas holders   can be installed at the following distance from residential buildings:

- up to 5m 3 or 5000 liters. - 20 meters;

- over 5m 3 to 10m 3. - 15 meters;

- over 10m 3 and up to 20m 3 - 20 meters.

As you can see from SNiP, the minimum recommended distance from an apartment house to a gas-holder is 10 meters. But it is practically impossible to observe such a distance. But in clause 8.1.6 there is a note that, under cramped conditions, it is possible to reduce the distance to 50% to the neck of the gasholder. It's about 5 meters.

You may also need to consider the following distances for installing gasholders:

- from public buildings and structures - 15 m;

- from children's and sports grounds and garages to the fence of the gasholder installation - 10 m;

- from industrial buildings and consumer service enterprises of industrial character - 8 m;

- from sewerage, heating mains of underground laying - 3,5 m;

- to above-ground structures and communications, overpasses, heating mains - 5m;

- up to the water supply and other non-channel communications - 2 m;

- to wells and underground utilities - 5 m;

- to motor roads of I - III categories, to the edge of the carriageway - 10 m;

- up to highways IV and V categories also to the edge of the roadway - 5 m;

And yet, do not forget about the convenient approach of the gas station to the gas-holder and the place for laying gas pipes to the house.

The price for installing gasholder.

Initial costs in early 2014 prices   about 400 thousand rubles.

Annual maintenance is approximately 10 thousand rubles.

The cost of refueling is calculated based on your needs.

Scheduled inspection after 10 years. Gastolder service life 20 years.

All other norms and technology for installing the gas holder will be in your project, if you, of course, decide to install it. Gazdolder thing is not cheap and convenience of using liquefied gas does not always cover the cost of its installation and operation. From experience, costs for heating with liquefied gas, excluding the cost of installing gasholdera approximately 6 times more expensive than with heating with natural gas, and taking into account the costs of operation and even higher. True, you can save here if you buy a portable gas turbine power station, the electricity produced by such a station is 5-6 times cheaper than the one we get from the state, but this option is possible only if you use liquefied gas for heating a cottage community. But do not forget that the cost of maintenance you will increase many times.

If you need more information about the cost of heating private houses with different types of fuel, I recommend to get acquainted with the article "".

The use of "blue fuel" for domestic needs has a significant drawback - the difficulty in implementing the delivery and storage. This defect has been overcome thanks to the gas holder - the "tank" for hydrocarbon liquefied gas. Furnishing autonomous gasification   obeys the set of requirements and standards. First of all, it is necessary to assess the parameters of the site, determine the distance from the gas tank to the house, the nearest buildings and communications.

The backbone gasification of remote settlements is not yet complete, and many settlements   remain without a convenient "blue fuel". An alternative solution for centralized gas supply is the installation of a gas generator and the arrangement of an autonomous network.

Gasholder is a monolithic tank for storing natural gas. Structurally, the tank is in the form of a tank with a neck. In the upper part there are elements that control the pressure and the remainder of the fuel.

Undoubtedly, the operation of any gas equipment is associated with a certain risk, so a number of requirements are presented to the location and technology of mounting the gas holder.

In the galgazer, the liquefied gas is gradually converted to steam, the propane-butane composition enters the reactor and acquires the required pressure. By the gas pipeline, "blue fuel" is supplied to consumers

The site for the installation of gas storage is assessed by the following criteria:

• relief;
• the composition of the underlying and enclosing ground layers and the proximity of groundwater;
• availability of water intake points, residential, economic and public premises.

Relief.   The area selected for installation must be level. This requirement is especially important when installing ground modifications - mounting on the slope is prohibited.

Priming.   It is acceptable to place the gas storage in soil massifs with different moisture content. From the physical and mechanical properties of rocks, the convenience of carrying out the land works and the choice of the type of gasholder will depend.

If there is no risk of flooding the valve, models without a high neck can be used. As an option, a tank, where the bends are attached to welded lengths of 12 cm in length - this "safety" height, if there is doubt about the flooding.

For places with "high" groundwater   Designs with an elongated neck providing protection of the reinforcement are developed. Due to the protection device, the operation of the gasholder is stable and effective

Water is an excellent conductor of heat waves, and the process of evaporation of propane-butane mixture determines the temperature of the medium. The higher the number, the more intensive the process. Mounting work in the lowland rocks is easier, but the environment for normal operation of the gas holder is less favorable.

Dangerous may be clastic soil, especially if its constituents are slightly rounded, i.e. with sharp edges. Boulders, pebbles and large rubble complicate the installation of equipment, and the mass of gravel and gruss creates an additional load on the gas pipeline. In any case, under the installation of gasholder, a pit is being developed, which it is recommended to fill with river or quarry sand after immersion of the structure.

Proximity to water intake sources. According to construction standards minimum distance   from the tank with gas to the reservoir (well, well) - 15 m, to the water main - 5 m.

Neighborhood with buildings.   Fire-fighting distances from containers with liquefied gas to structures are indicated in clause 8.1.6 of the normative document "Gas distribution systems" (SNiP 42-01-2002). The following section is devoted to this question.

The gasholder is more practical to place closer to the gate for unobstructed entrance of the gas carrier and refueling of the tank.

The site above the gas storage - a kind of exclusion zone. It is forbidden to equip a place for barbecue, install barbecues and other flammable equipment

In addition, concreting or paving of the site is unacceptable, as well as arranging a parking space and planting trees.

Fire protection distances to objects of protection

Determination of the optimal location of the gasholder at the site depends on the volume of the reservoir and the method of its installation: underground or above ground. For each option, strict norms are defined, which are unacceptable for explosive, ecological and fire-fighting requirements.

Volume - the determining parameter of remoteness of buildings

From the correct choice of volume depends not only the location of the capacity on the site, but also the ease of use. Litrage gasholdera is selected so that one refueling is enough for 1-1,5 years. The volume is calculated based on the area of ​​the house.

According to the norms, 20 liters of "blue fuel" per year are used for heating 1 sq.m of housing. If the gas is used in parallel for cooking, hot water, the figure is increased to 27 liters / year.

Knowing the dimensions of the house and the needs of the tenants, it's easy to make a calculation. For example, for a cottage of 200 sq.m, a gas tank with a volume of 4000 liters is suitable.

An alternative option is to determine the size of the tank by the capacity of the boiler plant. For example, for a 50-watt boiler, a 5000-gallon gas tank is required.

It should be noted that the maximum filling of the gas storage - 85% of the total volume, and the minimum fuel balance - 5%. Therefore, when choosing a gas holder, some reserve should be taken into account (plus 10-15%)

Norms for the location of underground gasholders

For year-round operation in cold winters, it is necessary to choose an underground "storage". The module is submerged below the ground freezing line, which maintains natural evaporation of the gas at sub-zero temperature on the street.

General standards of distance from underground reservoirs of any volume:

• sports grounds, children's complexes, garages - 10 m;
• underground pipeline of a heating main, sewerage - 3,5 m;
• external communications, not included in the backup equipment group - 5 m;
• the edge of the roadway of a non-high-speed road for 1-2 lanes - 5 m;
• motorways and highways for 3 or more lanes - 10 m;
• access tramway, railway tracks of industrial importance - 10 m.

The distance to the buildings of different purposes is determined by the capacity of the tank for liquefied gas. The gradation of values ​​is provided for "storages" in volume: up to 10 cubic meters, 10-20 cubic meters, 20-50 cubic meters.

Distance to residential buildings for single-unit containers up to 10 cubic meters - 10 m, up to 20 cubic meters - 15 m, up to 50 cubic meters - 20 m. Distance of public facilities - 15, 20 and 30 m respectively

Various standards are provided for the installation of a "repository" in relation to production facilities. The range of distances is 8-15 m. The distance to the general railways is 20-30 m, depending on the gasholder's capacity.

SNiP allows for a reduction in the interval between the residential building and the "gas tank" by 50%. However, such a decision should be justified by technical reasons and agreed in the local subdivision of gas distribution systems.

The distance should be calculated from the nearest point of the foundation to the wall of the gas holder. This norm is not stipulated in normative documents, but it is practiced when installing a gas storage facility

In addition to the requirements for the remoteness of the gas holder from different facilities, a list of rules for regulating the underground "storage" is provided:

• depth of installation - not less than 60 cm from the top wall of the tank to the surface of the ground;
• the distance between underground gasholders is at least 1 m;
• there must be free access to the neck and armature of the tank.

Regardless of the capacity, the underground tank is mounted on the foundation - a concrete slab. The base prevents the tank from "floating" in the event of ground movements.

Nuances of installing a surface tank

The use of ground gasholder has several significant advantages: simplicity, speed of installation and a decrease in the intensity of metal corrosion. Local lesions are easy to detect and correct in a timely manner.

However, this type of equipment is rarely used for gas supply to a private house. The main reason is a significant decrease in system performance in winter. At minus temperature (below -0.5 ° C), liquefied gas does not evaporate naturally. To maintain the process, the gas reservoir is required to be equipped with an evaporator. With a small expenditure of "blue fuel", capital investments in gasification pay off very long.

Due to the ground location, the requirements for fire protection distances from the gas storage to buildings and other facilities are more stringent.

The minimum distances are given separately for three groups of standard sizes: up to 5 cubic meters, from 5 to 10 cubic meters and tanks with a capacity of 10-20 cubic meters. The "+" sign indicates the distance from the gasholder to real estate objects not serviced by the installation

Additional restrictions on the location of the ground "gas tank":

• general railways - 25-30-40 m in accordance with the volume;
• tram and railway lines of local destination - 20 m;
• roads IV-V category (1-2 lanes) - 10 m, I-III category (from 3 lanes) - 20 m.

For safety reasons, a kind of open hood is arranged over the gas tank, protecting the module from direct sunlight and precipitation. Overheating of the tank or lightning can lead to an explosion, and rain and snow to accelerated corrosion.

Placement of mobile gas storage facilities

Mini gasholder - roomy gas cylinder   volume up to 500 cubic meters, equipped with the required for safe operation of the valve: gearbox, level gauge and safety valves. The equipment is compact in dimensions, for example, the parameters of a reservoir for 480 liters are: length - 2 m, diameter - 60 cm.

With proper use, the lifespan of the "balloon" is the same as for a full-size gasholder. The mini-model is placed permanently or installed on a trailer, which ensures the mobility of the gas storage. The capacity can be filled in the place or at the station.

An important advantage of the mini-gas holder is the absence of strict requirements for its placement. Works on connecting the tank to the gas system   houses take about two hours

According to SP 63.13330 from 2011, the minimum distance from home to a small gas holder is acceptable, namely the placement directly at the wall. Remoteness of equipment from other protection facilities is not stipulated.

Mini gas holders are in demand to provide autonomous gasification of premises with relatively small or seasonal fuel consumption: cottages, heating cafe areas, a hotel. The reservoir is often used as a reserve source of gas in case of interruptions with a centralized highway.

Requirements for gas pipeline laying

Certain standardized standards are also imposed on the construction of a gas pipeline from the gasholder to the house. The gas is fed into the room through the underground pipeline through the basement entry. Safety rules prohibit the entry of a gas pipeline into the house by underground.

The scheme of entering the trunk pipe into the house. Legend: 1 - gasholder, 2 - concrete slab of the base, 3 - condenser collector, 4 - underground pipeline, 5 - subassembly unit

General requirements for laying a gas pipeline in the section "gasholder-house":

• depth of track - not less than 1.7 m;
• width of the trench - strict limitations are not provided, the value depends on the length of the pipeline and the quality of the ground;
• the minimum slope towards the condensate collector is 1 cm per 1 m (no more than 5 °), the maximum spacing is 100 mm;
• distance from the main to the foundations of buildings - 2 m and more;
• distance to parallel lines of communication - 1 m, with a cross arrangement - 2 m in height.

The underground gas pipeline is installed from polyethylene pipes   high density with nitrile content. Ground line - steel gas pipes. Polymer piping should not reach the point where the soil temperature is lowered to -20 ° C or less.

The transition of the polyethylene-steel pipeline is carried out at a depth of 40 cm. The site must be protected from electrochemical corrosion - a polymer coating is used up to a height exceeding the ground level

Safety of gasholder operation

Despite all the advantages of autonomous gasification, many consumers are deterred by the thought of the risks of storing a flammable substance on the site, near a residential house. To ensure safety, it is not enough to withstand the required distances during installation, it is necessary to comply with all the conditions for filling, operating and servicing the gas-holder plant.

Operational rules:

1. Preservation of an inexhaustible stock - about ¼ of the volume. When using all fuel in the tank, a vacuum is formed, with further refueling with a violation of technology, an explosion is possible.
2. Filling gasholder exclusively specializing company. Insignificant savings on the services of unskilled gas workers can lead to a fire.
3. Checking the operation of the safety valve. Timely troubleshooting will prevent an emergency.
4. Prevention of gas leakage. The flow of "blue fuel" is most dangerous - the propane-butane mixture "spreads" down, because it is heavier than air.

The probability of fuel leakage exists when the tank is damaged, the valve is malfunctioning, unqualified repair or refueling, or when the gas distribution system is leaking.

The safety of operation and refueling is ensured by the equipment: 1 - the remnants of the condenser collector, 2 - safety valve, 3 - reducer, 4 - gas pipeline, 5 - level gauge - measurement of tank filling, 6 - refueling valve, 7 - gas vapor extraction valve, 8 - manometer, 9 - liquid gas extraction valve

The mandatory precautions include the use of lightning protection and grounding. Near the gas holder it is unacceptable to conduct welding operations, to kindle a fire.

Video: arrangement of autonomous gasification
