Not every resident of Russia has the opportunity to connect to a central heating system. As a way out, you can heat your home with electricity alone, but this idea will be immediately rejected after the first housing and communal services receipts arrive. A real alternative to main gasification is a gas tank. Millions of Russians have already become convinced that this is a fairly effective solution.

Why do you need a gas holder?

English word gasholder in Russia they call it special tank for long-term storage of gaseous substances in liquefied form. The scope of such devices is very wide, but most often they are used for gasification of a private home.

The container is mounted at a distance of about ten meters from the dwelling and is connected to the latter by pipes. Approximately 2-3 times a year you need to refuel by calling a tank truck to your home.

Among the most frequently cited reasons for installing this type of equipment:

• Inaccessibility of connection to main gas networks or prohibitive cost of such work;
• A specific option for using gas in a residential building. In some cases, a gas tank can be cheaper than a conventional gas pipeline in terms of maintenance and monthly expenses. Compared to gas cylinders, the savings are even more obvious;
• Consumer dissatisfaction with the quality and level of operation of gas pipelines. Often the pressure level in the pipeline is 1/3 of the standard. The main reason for this situation is the large number of illegal connections to the network.

Selecting a natural gas storage tank is quite a difficult task. It will be almost impossible to change it later: the standard service life is 20-30 years. Let's list the most important selection criteria quality product:

• Gas tank volume. Containers ranging in size from 2 to 10 kiloliters are available for sale. The key characteristic is the living space. For a house up to 140 sq.m. m. there will be enough volume up to 5 cubic meters. m. With an area of ​​300 sq. m will need about 7 cubic meters. m;
• When choosing gas tank size You should also take into account the number of people living in the house, as well as the brand of the heating boiler (if you already have one);
• Calculations are being made fuel consumption, based on the duration of the cold season in a given area;
• Manufacturer. Most buyers choose products from the domestic plant "Faskhimmash" (Nizhny Novgorod). Products from countries such as Poland, the Czech Republic and Italy are somewhat more expensive;
• Device features. Experts note the need for a hatch on the product (on the neck). Also, preference should be given to the horizontal form factor;
• Price. Both capacity and brand play a role here. On average, the device is about 6.5 cubic meters. m will cost about 400 thousand rubles (including all work). For 10 cu. We will have to pay 30% more.

Gas tank or main gas: which is cheaper?

For owners of private houses, especially in the outback, it will be important to compare two home gasification technologies:

• In terms of connection costs, a separate tank will cost several times less than laying pipes;
• It must be borne in mind that the tank requires constant maintenance, which is quite expensive (about 10,000 rubles);
• In most cases, owners of gas tanks are faced with the impossibility of changing service companies throughout the entire service life of the device;
• Not every personal plot is allowed to install a container. There are increased requirements for space (small gardens of 6 acres are not suitable), it is necessary to have access for a vehicle;
• The quality of service for trunk systems leaves much to be desired.

In reality, comparing the two technologies is not entirely correct. In the vast majority of cases, consumers select the main pipeline, if it is within close reach for connection.

On the other hand, gas tanks are practically the only available solution for residents of remote areas.

Installation Rules

The installation process of this complex equipment is as follows:

1. Choosing a place to install the tank (at least five meters from where people live);
2. Workers are digging a pit that can accommodate a voluminous cylinder. The depth of the pit should be such that the container is located below the freezing zone (more than half a meter from the surface of the earth). This way it will be possible to achieve more comfortable work in winter;
3. After the pit is ready, you need to prepare its base for installation of the structure. The bottom of the pit is leveled and then concreted;
4. The tank is installed on a concrete base and attached to it with metal cables;
5. Then the pipes from the gas tank to the living space are installed. As a rule, a condensate collector is installed in parallel;
6. Testing the system operation under various loads;
7. If the previous stage is successfully completed, the hole is filled with sand;
8. Absolutely all manipulations must be reflected in the design documentation.

All work can be done both during the construction of the house and after completion of construction.

What is Bast's "Gas Holder"?

The music label “Gazgolder” was created by Soviet and Russian pop singer Bogdan Titomir. The latter has already moved away from writing songs to producing young talents.

In 2005, Bogdan drew attention to the debut album of Vasya Vakulenko, known under the pseudonym “Basta”. He liked the disc so much that Titomir invited Basta and his comrades to found a creative association.

Today, the permanent members of the label are such performers as:

• Smoky Mo;
• Charusha;
• Scriptonite;
• Oleg Gruz;
• Slovetsky.

In addition to the core activities of recording and promoting musical compositions, the Gazgolder brand is known for a cafe, a company for organizing concert events, and a night club. In 2014, a full-length film of the same name was released based on the life of the union members.

Today the label is one of the most popular and successful in Russian-language rap.

Natural gas storage tank , installed on the territory of a private house, is called a gas holder. However, not everyone knows that this is the main meaning of the term. After all, there is a well-known hip-hop label that has gathered under its roof the best of the best in Russian rap.

Video: comparison of “Gas Holder” and “Black Star”

In this video, Olga Maslova will compare two well-known Russian labels - Black star and Gazgolder:

A gas holder is an important part of the autonomous gas system of any residential suburban area. This is the best alternative that works or. Nowadays, when housing and communal services tariffs are constantly rising, the use of such devices in private homes is not uncommon.

A gas holder helps to provide a home with heat, hot water and gas economically and for a long time, regardless of the prices for housing and communal services, and also makes it possible to generate its own electricity.

What is a gas holder

A gas tank is a vessel containing liquefied natural gas, consisting mainly of methane, butane, a mixture of propane and butane. Its volume is calculated based on gas consumption for the entire season.

It has been established that the average volume of gas consumed by a residential building with an area of ​​up to 200 square meters is 20 liters per square meter. From this we can calculate that the volume of gas required for heating throughout the entire winter season (6 months) will be 4000 liters.

Device

The gas holder vessel can be made of steel or reinforced concrete. According to the principle of gas storage, all gas tanks are divided into tanks with constant and variable volume. A variable-volume vessel contains inside a vertical cylinder of water, in the lower part of which there is a bell. As the gas from the container decreases, the bell in the cylinder moves down, creating a constant pressure necessary to supply the entire gas system.

Previously, such gas tanks were used not so much for long-term gas supply as for maintaining constant pressure. Now they are gradually going out of use, however, some continue to work in large enterprises. For example, a variable-volume gas holder is still in operation at the domestic chemical enterprise Kazanorgsintez, as well as at the Obvodny Canal in St. Petersburg.

Unlike the gas tanks described above, which contained gas with a pressure slightly higher than atmospheric, modern gas storage facilities of constant volume can withstand pressure of up to 18 atmospheres. Modern technologies make it possible to create durable alloys that can withstand enormous loads, the environment of liquefied propane, and also to exercise full control over gas pressure. All modern gas tanks have a constant volume.

Principle of operation

The operation of an autonomous gas system is similar to a conventional one. The main difference is the gas supply source and piping layout. Evaporating, the mixture of propane-butane fraction enters the reactor, where it acquires the required pressure. The gas is then distributed through the gas pipeline junction to the fuel consumer.

The frequency of refilling the gas tank depends on the degree of gas consumption and the volume of the gas storage. If the volume of the gas tank is correctly selected, the gas should be enough for at least one year. Liquefied gas can be stored in a container for a large amount of time without changing its composition or quality. To install a gas holder, it is necessary to take into account the distance to residential buildings. The main condition for the correct location of the container is the availability of free space in front of the house or cottage.

Note: According to safety requirements, the minimum distance from the gas tank to any building must be at least 10 meters.

Varieties

According to their location in space, all gas tanks are classified into:

• ground;
• underground.

Due to the harsh Russian climate, gas storage facilities are rarely located above ground. The underground location option ensures good evaporation of liquid gas without the use of additional evaporation devices, even in the cold season due to weak soil freezing at depth. The gas tank must be buried to a depth of at least 60 centimeters from the surface of the earth.

The gas tank must be installed using a crane on a specially prepared concrete slab. Each vessel must be covered with a special protective coating against electrochemical corrosion. In the lowest section of the gas pipe running from the tank to the house, there should be a condensate collector that collects the liquid that is formed when the gas evaporates.

According to the type of construction, all gas tanks can be divided into:

• vertical;
• horizontal;
• mobile (mobile).

Containers placed vertically in the ground have a much smaller evaporation area than horizontal vessels. This explains the widespread use of horizontal gas holders. In some cases, vertical gas tanks are installed in pairs to increase the evaporation surface.

Mobile gas storage facilities stand separately among all gas tanks. A mobile gas holder is a small gas tank (its volume is usually 500 l), equipped with a heating system. Such a container is convenient to refill and can always be delivered to any place that is not equipped with a gas system.7

Advantages and disadvantages

Despite the obvious advantages of this type of gas supply, gas tanks also have their disadvantages, which also need to be taken into account, namely:

1. The price of the container itself and its installation is quite high.
2. Due to the small distribution of such installations throughout the country, it is quite difficult to find a company that will install it correctly and properly service it.
3. When purchasing a used gas tank, the likelihood of its malfunction increases significantly, which is unacceptable, given that it will be located in the middle of the residential sector.
4. It is not always possible to install a gas tank in accordance with safety requirements.

Before purchasing a gas holder, be sure to weigh all the pros and cons of using it. You also need to take a very responsible approach to choosing an installation and maintenance organization and ensure that the gas tank is installed in full compliance with safety requirements.

Organizing an individual gas supply gives a lot of advantages to the owner of a private house, removing his dependence on central communications. In addition, many regions of the country still do not have full coverage of main gasification. In this case, it remains to think through ways and means of storing explosive and therefore demanding fuel. The most rational and financially beneficial solution is a gas tank. What it is? It is a capacious tank that can store an impressive supply of gas, sufficient for long-term maintenance of the house.

Purpose of the equipment

The gas holder is used as a source of gaseous substances. On the one hand, it acts as a storage facility, and on the other, as a container from which fuel is provided to supply the target equipment. The most common installations are for heating systems. It is for these purposes that gas boilers and boiler tanks, as well as cookers, are often used. Delivery means are pipelines and adjacent communications with plumbing fixtures. At the same time, the gas for a gas holder can be different, but butane and propane are most often used for domestic purposes.

Equipment design

The traditional design is a solid container, the upper part of which provides only one technological hole - the neck. The higher it is, the more effective the protection of the main body from climatic influences. Through the neck, the fuel mixture contained in the container is refueled and withdrawn. The features of the device include the materials used for the gas tank. What is this from a technical point of view? The design of household models is made primarily of steel with rare inclusions of rubberized materials that provide a sufficient degree of tightness. Domestic gas tanks are mainly based on low-alloy steel alloys of grades 17G1S and 09G2S. The outer sides must be treated with anti-corrosion compounds made from polyurethane substances, bitumen and epoxy mixtures.

Work processes and equipment control are carried out through shut-off and control valves. Its composition may vary, but even the simplest gas holder for a home will include safety and filling valves, fill level sensors, a control gear, etc. Expensive models include automation with high-precision pressure gauges and program control.

Tank characteristics

The main technical and operational characteristics include wall thickness, operating temperature, maintained pressure and volume. Typically, sheet steel with a thickness of 7-10 mm is used in production. It must be borne in mind that European standard models may have lower values ​​- about 5-6 mm. But thin walls are not designed for storing domestic gas mixtures. For gas tanks in Russian regions, liquefied propane-butane without special processing is more likely to be used, so the requirements for design reliability are increasing. The temperature range also depends on the region of operation. As a rule, manufacturers provide housings with frost-resistant coatings designed for -40°C.

As for volume and pressure, these indicators are interrelated. For home use, it is recommended to purchase a tank with the ability to adjust pressure to 16 atm. In this case, the volume of the gas tank will be 2,000-5,000 liters. There are also household models with a capacity of more than 10,000 liters, but due to their size, such gas storage facilities are used extremely rarely.

Types of designs

Tanks can be installed horizontally or vertically. The location method determines the design features of the housing. The difference is that vertical models take up less space but have higher safety requirements. If there is a high groundwater level at the location site, then it is better to use a horizontal gas tank design. Reviews note that in this case a deep pit is not required and the risk of equipment flooding will be minimized. But on the other hand, you will have to clear a large area for storage.

Designs are also distinguished by the type of location. This classification also applies to horizontal models, which can be completely submerged in the ground or installed on the surface. Moreover, the differences in approaches affect both control ergonomics and maintenance nuances - it is enough to note the specifics of technical support for an underground gas tank. What is this in practice? This is equipment that once a year or several years will need to be dug out and checked for a wide range of technical and physical parameters - from tightness to the quality of protective coatings. And in this regard, ground-based models are much more attractive in terms of maintenance costs and ease of management.

Gas tank installation

Regardless of the placement method, the structure will require a supporting platform. This will be a kind of foundation, which can be made as a screed or using reinforced concrete tiles 15-20 cm thick. On this platform, with the support of special equipment, the tank is mounted by welding on metal racks. Alternatively, the installation of a gas tank can be carried out without holding devices on an insulated composite pad, which is selected specifically for the dimensions of a particular container. This solution is advantageous in that during dismantling it does not require cutting the metal posts. Then plumbing operations are performed in the form of laying a pipeline and installing a condensate trap. At the final stage, control valves are installed in part of the neck.

How is a gas tank filled?

Fuel reserves are replenished on average once every 2-3 years. Moreover, this service should be ordered when the residual gas level in the tank is about 20-25%. The refueling itself is carried out by special machines equipped with hoses 30-40 m long. The whole process consists of the following stages:

• Clearing the area around the equipment and preparing the neck.
• Checking data from measuring equipment showing the exact filling level.
• Connecting the tank nozzles to the special equipment hose.
• Resetting automatic measuring counters.
• Fuel supply and gas tank refueling supported by pumps or compressor unit.
• Removing gas residues by blowing the channels with compressed air.
• Dismantling of connected equipment.

The entire procedure takes on average from 30 to 60 minutes. This depends on the fuel injection technology and the capacity of the gas tank. Reviews from equipment owners note that it is cheaper to order large volumes at a time. For example, filling 30% will cost approximately 20-22 rubles. for 1 liter, and 70% - respectively, 15-17 rubles.

Manufacturers and prices

In the engineering equipment market, gas tanks are presented in different segments, including the budget class, the middle group and the premium category. The most notable manufacturers are Spetsgaz, Real Invest, Chemet, Calor, VPS and Kadatec. The first two companies represent domestic enterprises, and the rest - Poland and the Czech Republic. As already noted, Russian products are preferable due to their adaptation to the target region of use, but European companies manufacture models to more stringent quality standards. The pricing question can help solve the selection problem - how much does a gas tank cost? Russian models for 2,000 - 2,500 liters are estimated at 130-150 thousand rubles. Imported products of a similar level are available for 170-200 thousand.

Calculation of model parameters

Before making the final decision to purchase a gas tank, you should decide on specific characteristics. To do this, first of all, the average gas consumption is assessed. If cylinders were previously used, then the average monthly volume is multiplied by 12. Next, the area of ​​the cottage or house is divided by 10 (approximate boiler power in kW). If the area is 120 m2, then the target boiler installation will be 12 kW. Accordingly, you need to choose a gas holder for your home with a volume capable of serving a heating unit of the specified power, while maintaining a supply for several months or years in advance (for example, with a consumption of 500 liters per year). Here the optimal frequency of refilling the container is also calculated from the point of view of financial savings and technical feasibility.

Finally

In addition to the many advantages of this storage, it is worth noting its disadvantages, which you will also have to come to terms with. Thus, it is necessary to take into account the high requirements for alarm and safety systems of the gas tank. What is this at the everyday level of execution? First of all, the presence of leakage sensors in critical places at the distribution nodes and connections of supply lines. Detectors must be connected to their own or centralized control system with an alarm and an option for wireless alarm notification. Also, for the boiler itself, connected to the gas tank, electrical protection is provided in the form of fuses and voltage stabilizers.

Gazgolder (Gas holder) is a Moscow label specializing in Russian rap and hip-hop, as well as in some places in other areas of modern music. At the beginning of 2014 the film “ Gas holder" Released at the beginning of 2014 film "Gas Holder". This film was released in theaters on April 24, 2014. This rap label is based not only on old proven heavyweight artists (Basta, Smokey Mo, Triagrutrika and others), but is also actively recruiting young people (an example of this is at least together with the Kazakh artist).

In 2005, under the auspices of the emerging platform, Basta and company (presumably other people who prefer not to be seen for obvious reasons are also behind this) created a place where their friends and like-minded people were attracted. Club " Gas holder" opened quickly, in March, not yet fully renovated. It quickly turned into a home where one could simultaneously live, create, hang out and indulge in bold and unexpected adventures. Numerous, often closed parties and art projects soon brought the club Gazgolder status of a significant cultural center of the second half of the 2000s. Almost immediately, the creative association had its own coat of arms (logo), symbolizing the word gaz-holder itself and the unity of spirit of its inhabitants.

The creative association "Gazgolder" is one of the most successful Russian record labels, actively promoting aspiring rap artists.

"Gazgolder" is a huge holding company that includes: a production center, a club, a management and booking agency for artists.

On the basis of the popular brand, cultural events, music festivals are held, films are produced, and trendy videos are shot.

The history of the founding of a rap empire

In March 2005, on the territory of the empty Arma enterprise, Ruslan Tarkinsky founded the closed club “Gazgolder”. A little later, with the assistance of the famous rapper of the early 90s, Bogdan Titomir, a creative association of the same name was opened on his base. From that moment on, the collaboration between the aspiring Rostov rapper Vasily Vakulenko and Titomir began, who became the guy’s producer.

The co-owner of the famous brand “Gazgolder” is Evgeniy Antimony. The co-founders were Denis Kryuchkov and Yuri “ZHEora” Bulavin. In 2006, on the basis of Gazgolder, the Rostov rapper recorded his debut album Basta-1. With its release, the colorful musician’s career rapidly took off. In 2007, Vakulenko became a co-owner of the Gazgolder music association.

In the same year, Andrei Zuckerberg founded a small teahouse on the territory of the former Arma gas enterprise. In 2009, representatives of the label inaugurated a Chinese restaurant.

Since 2010, Gazgolder artists organize big concerts every year. The first venue was the Green Theater in Gorky Park, where thousands of Bast and Guf fans gathered.

New “old” faces of “Gazgolder”

In 2011, the creative association “Gazgolder” was replenished with new charismatic participants. The first to join the label was the extraordinary group “Triagrutrika”, which included three rap artists from Chelyabinsk: MC Jahmal - Artem Averin, MC Vibe - Evgeniy Vibe, MC Ingyshit aka Big Mic - Mikhail Aniskin, MC and beatmaker Dj Puza - Nikita Skolyukhin.

The Triagrutrika group has five solo albums: “Unlegalized/ZdNA”, “Evening Chelyabinsk”, “T. G. K. lipsis", "Basing", "By Triagrutrika, Pt.1". In 2016, the guys’ contract with the Gazgolder music label expired. But at the same time, Basta’s creative relationship with his charges remained strong.

Following the Triagrutrika team, the eccentric rapper Alexander Tsikhov, better known under the pseudonym Smokey Mo, joined the Gazgolder team. Today, Smokey Mo's creative collection includes seven solo records. One of them was recorded together with Vasily Vauklenko.

Together with the project “Zloi Negr”, Smokey Mo recorded two mixtapes “Armor of God” and “Armor of God-2”. In these records you can hear: Slava CPSU, Piku, Kyivstoner, D.masta, Nigativ, Yanix and Loc-Dog.

In February 2014, Adil Kulmagambetov, performing under the creative name Scryptonite, joined the top label. His tracks became popular not only in Russia, but also abroad.

The album “House with Normal Phenomena” was recognized as the best rap album of 2015. Today it boasts four studio albums: “House with Normal Phenomena”, “718 Jungle”, “Holiday on 36 Street”, “Ouroboros Street: 36/Mirrors”.

In the winter of 2016, a pre-premiere screening of Sergei Solovyov’s film “Ke-Dy” took place at the Gazgolder club. One of the main roles in it was played by the Rostov rapper Basta, who had to reincarnate as a soldier. Vakulenko recorded the soundtrack and several songs for the film.

In July of the same year, the first broadcast of the entertainment program “Gazgolder Live” was broadcast on the DFM radio station. As part of the project, Basta, together with Sergei Mezentsev and Vadim Karpenko, spoke with famous media figures in the studio. In 2017, the decision was made to close the program.

Scandals and departure of artists

In September 2016, an artist of the creative association "Gazgolder" Murassa Urshanova, better known as Tati, announced her departure. The singer posted an angry post on one of the social networks, where she accused Vakulenko and his team of hacking her personal page on Vkontakte. Basta himself learned about his ward’s action later from online news and responded to the girl with a sarcastic video.

After the departure of the scandalous performer Tati, the label warmly welcomed the young actress Daria Charusha, who decided to pursue a career in the music industry.

The girl recorded the soundtrack to her husband Ilya Naishuller’s film “Hardcore”. A few months after signing a contract with Gazgolder, Charusha presented her debut album “Forever”.

Following Tati, the Ukrainian project “Nerves” and the Belarusian Tony Tonite left the music label. Although the contracts with these performers have not been renewed, they continue to cooperate with Basta.

In 2017, new faces joined the Gazgolder team: rapper and metropolitan performer Sasha Chest. The first artist comes from Ukraine, his real name is Kirill Nezboretsky. T-Fest gained popularity after recording a joint track with Scriptonite, called “Lambada”, as well as the composition “Reboot”.

In July 2017, as always The annual festival “Gazgolder Live” was held at a high level. Not only residents of the creative association, but also invited artists performed on the big stage. Among them: MiyaGi and Endgame, ATL, Husky, Jillzay Cvpellv.

In August of the same year, a group from Nizhny Novgorod “MODI” was presented, working in such directions as rhythm and blues, funk, trap soul.

At the end of 2017 The bright artist Matrang joined the creative association, who blew up the popular charts and dance floors with the track “Medusa”. Fans compare Alan Khadzaragov, a native of Vladikavkaz, with the legendary performer of the 90s Viktor Tsoi.

Another mentee of Vasily Vakulenko is Valentin Presonov, who performs under the pseudonym Slovetsky. In addition to developing a musical career, the artist is working on his own line of youth clothing.

In 2018 creative The Gazgolder association presented the comedy film Klubare by Ivan Kursky. The film premiered on October 11 and received positive reviews from viewers. The main roles in the film were played by Vasily Vakulenko and the popular actor Evgeny Stychkin.
