Of all the “utility services”, gas is the most “nasty”. Let’s ignore the cost of connecting to gas networks, which does not seem reasonable at all. The gas pipeline may run right along the border of your property, but for the “connection” of two meters of pipes they will charge you more than a thousand dollars. This is what the “service organization” will take from you, in my case OdessaGaz. In addition, at your own expense, you will design and build a gas pipeline that will run through your site and to the appliances inside the house. Needless to say, both the design and installation of this gas pipeline are carried out by “licensed” enterprises who also want to eat, and eat well. In general, a situation where the seller of a product requires the buyer to build an infrastructure for the delivery of goods seems absurd to me. It's like buying a milkman a car so he can sell you milk in the morning.

What follows is even more interesting. After you pay for all this infrastructure for delivering gas to your home, they also begin to dictate to you some requirements for its maintenance exactly in the form in which it is convenient for the gas service, even if this contradicts your desires and existing standards.

For example: such a cute coloring of gas pipes in a poisonous yellow, which our gas workers love so much and which they want to see on all facades, regardless of their color.

Not the best aesthetic option.

We take DBN V.2.5-20-2001, Gas supply. Let's read. We find that “gas distribution points” are painted yellow, not gas pipelines low pressure for residential buildings. A gas distribution point is something like this:

For low-pressure gas pipelines used in residential buildings, only the number of layers of primer and paint is established, plus the type of painting material (which is logical - the gas pipeline must be protected from corrosion), but not the color. So the demands to disfigure your façade can be safely ignored.

The next interesting point is the ban on “ hidden installation» gas pipelines indoors. According to gas service workers, this means that all gas pipes inside your house should stick out in plain sight (and also be painted yellow, yeah) and you cannot sew them up with anything. When they told me this the first time, I simply shrugged it off, but during the installation process I was persistently taught the idea that these pipes on the walls are now part of my life and it’s better for me to make friends with them right now. I had to rummage through the same DBN again, after which it turned out that hidden installation of a gas pipeline is an absolutely permissible thing, you just need to provide access to it using some kind of removable panels and ventilation of the space in which it is located. Again, quite logical requirements - if you have a leak, it is in your best interests to smell it as quickly as possible so that the gas does not accumulate in a closed space.

So we are fighting the insanity of gas services with actions of civil disobedience - we paint the pipes in any color that suits us and hide them behind beautiful panels!

Gas pipes are designed to transmit gas at different pressures and over different distances. This kind of communications can be laid both underground and on the surface. In any case, they need special labeling. Gas is flammable and explosive, so the gas pipeline offers a large potential danger. Painting of gas pipes on the street is carried out in accordance with the relevant GOST requirements.

Rules for painting outside and inside the apartment

GOST 14202-69 defines exactly what color and with what identification marks a pipeline for any purpose should be painted. Thus, both the team arriving for repairs and people living nearby can immediately determine which communications have been damaged and what danger they pose.

Gas pipes are designed to transmit different gases and are marked accordingly:

• gas pipeline natural gas painted yellow without additional rings;
• pipes for acetylene transmission are painted white;
• oxygen supply products are blue;
• compressed air indicated by deep blue;
• carbon dioxide transfer is indicated in orange.

Painting of a gas pipe running along the facade of a building and on the street is rarely done along its entire length. Firstly, the highways are too long, and secondly, the multi-colored segments spoil appearance facade. As a rule, individual areas are painted in order to designate the system.

Identification staining is used in certain areas: at junctions during branching. Painting gas pipes on the facade of a house that pass through a wall must include an appropriate color marker. Painting a pipe passing through a wall.

Inside a building or home, gas pipes are painted in accordance with the requirements of the interior. As a rule, base coloring linear meters gas pipeline is white. A gas pipe passing through a wall is not specially marked. Painting services are provided by the builders themselves.

Paint selection

The paint for painting gas pipes in the house or on the street is also selected in accordance with certain requirements.

Its main goal is to prevent corrosion of metal gas pipes, however, there are differences between compositions for indoor and outdoor use.

The question arose from the condominium association in connection with an inspection and an order for mandatory painting of the gas pipeline on the territory of the house.

The conditions for the transfer of housing stock are regulated by part 4 of article 7 of the Law of Ukraine “On the transfer of objects of state and municipal property rights” No. 147 / 980VR dated 03/03/1998. Thus, built-in and attached premises are transferred along with the housing stock, external gas supply networks , as well as buildings intended to serve this fund. Facade gas pipelines multi-storey buildings from the shut-off device at the exit of the gas pipeline from the ground to the facade of the building to the entry of the gas pipeline into the house refers to engineering home communications .
According to 4.15. Safety Rules for Gas Supply Systems, approved by Order of the Ministry of Energy and Coal Industry of Ukraine dated May 15, 2015 No. 285, above-ground, above-ground and internal gas pipelines, as well as fittings must be protected from atmospheric corrosion in accordance with the requirements of DBN V.2.5-20-2001 "Gas supply" and painted (with the exception of internal gas pipelines of residential and public buildings) in accordance with the requirements of GOST 14202-69 "Pipelines of industrial enterprises. Identification painting, warning signs and marking panels" and GOST 4666-75 "Pipeline fittings. Marking and distinctive painting". Owner ( balance holder and/or lessee (tenant)) must monitor the condition of the house inlet gas pipeline and its fastening, paint the specified gas pipeline at least once every 5 years (clause 1.14 of these Rules). Inlet gas pipeline - a section of the gas pipeline from the disconnecting device at the entrance to the house (when installing the disconnecting device outside the building) to the internal gas pipeline, including a gas pipeline laid in a case through the wall of the building (clause 2.1. of the Rules).
Let us note that the point of distribution of external and internal communications for the gas pipeline is the valve near the building (according to clause 2.3.7 of the order of the State Committee of Ukraine on Housing and Communal Services No. 76 dated May 17, 2005 “On approval of the Rules for the maintenance of residential buildings and adjacent areas” ). On balance PJSC "Odessagaz" there are gas pipelines up to the valve (valve, shut-off device) at the entrance to the house. Gas pipelines after valve (valve, shut-off device) are included in the book value of the building and are on the balance sheet of the owner (balance holder and / or tenant (tenant)) of the house and must be maintained at the expense of the owner (balance holder and / or tenant (tenant)) of the house, or a person who, under an agreement with the owner, maintains the house.
In addition, according to paragraph 5 of clause 5.10. of these Rules, the owners (balance holders and / or tenants (tenants)) of residential and public buildings, public utilities and consumer services population.
According to the Regulations on the procedure for the maintenance of in-house gas supply systems of residential buildings, public buildings, household and utility enterprises, approved by order of DAHP “Ukrgas” dated July 30, 1997 No. 35, “ The balance holder must provide conditions for timely painting and repair of house gas pipelines ».
To carry out work to replace faulty elements of the gas supply system or repair them, the balance holder must enter into an appropriate agreement with a specialized gas supply and gasification enterprise that has the appropriate license and permit for this, for example, with PJSC "Odessagaz". Work on painting gas pipelines can be carried out both by the owner of the house and PJSC "Odessagaz" under the terms of the contract. PJSC "Odessagaz" will be able to complete the above work on time and under the conditions provided for in the agreement concluded with the owner of the house.

Accordingly, work on painting the gas pipeline after the valve must be carried out by the balance holder at home. If the condition of the gas pipe in some places leaves much to be desired, it is recommended to conclude an agreement between the condominium association and PJSC "Odessagaz" to conduct painting works external gas supply networks at home.

What and how to paint a gas pipe? In this article we will have to decide what colors are acceptable to use, what types of paints should be preferred and how to apply them correctly.

Why is this necessary?

Painting a gas pipe is not at all a tribute to aesthetics.

It has two goals:

1. Pipeline color identification in the conditions of industrial enterprises, gas boiler houses, etc. Agree, determining the functionality of a pipe by color is much easier than lifting documentation to the junction in front of you.

Important: as we will see later, color marking is used only in industrial conditions or on the ground, when laying overhead gas pipelines. Any requirements local authorities regarding the color of pipes on the facade of a residential building or inside its premises are unauthorized.

1. Anti-corrosion protection. Since the environment inside the pipe is devoid of oxygen and water vapor, its service life depends solely on corrosion resistance outer covering.

Color

So, what color should gas pipes be?

The source of information for us will be the safety rules for gas distribution systems PB 12-529-03, where paragraph 2.3.9 clearly states:

• Aboveground gas pipelines are painted with two layers of yellow varnish, enamel or paint. The coating must be intended for outdoor use. Color coding pursues identification purposes.
• External gas pipes running along the surface of the building facade can be painted to match the color of the building envelope.

The painting of gas pipelines inside apartments and private houses is not regulated at all in terms of color choice.

At home - any colors and shades.

We are looking for the owner

Who should paint a gas pipe? The question of this constantly comes up in the most different regions countries - from quiet courtyards on the outskirts of the capital to small villages in the wilderness. Alas, the person responsible for the condition of the gas pipeline has to be looked for separately each time: everything is determined by the terms of the contract for Maintenance gas pipeline.

In general, areas of responsibility are distributed as follows.

Apartment buildings

Internal gas pipelines of apartments are painted by residents. Pipes passing along the facade, entrance or street - by the gas supplier or utility services (again, depending on the terms of the service agreement). The boundary between areas of responsibility is the apartment wall.

Attention: we're talking about just about painting. Maintenance of shut-off valves is performed only and exclusively by the gas service.

Private sector

Gas pipeline in the territories common use serviced by gas workers, on private property - by their owner. Gas pipelines passing through private property can also be serviced by the gas supplying organization; however, in this case, it will be quite reasonable for her to bill for their periodic painting ().

Private territory— area of ​​responsibility of the owner of the site.

Types of paint

What kind of paint can be used for a gas pipe?

External gas pipelines

In short, absolutely any anti-corrosion coatings for outdoor use are suitable for our purposes.

• Alkyd enamels (PF-115) are a time-tested classic. It forms a thin, durable coating that is resistant to any atmospheric influences. The service life is at least five years, the price of a kilogram of paint is 40-60 rubles.
• Polyurethane paints are distinguished by excellent adhesion to any substrate, elasticity and even greater durability: in the most difficult conditions they last at least 10-12 years.
• Two-component epoxy coatings are less elastic, but extremely wear-resistant.
• Dispersions of aluminum or zinc powder in organic varnish are probably the most reliable corrosion protection. Thus, Zinga electrically conductive paint, after drying, creates a thin zinc film on the surface of the pipe, which increases the service life of black steel to several decades.

The photo shows silver, a dispersion of aluminum powder in organic varnish.

Internal gas pipelines

Here, in addition to exterior paints, interior paints can be used. The only limitation is that you should not use coatings that are marketed as vapor-permeable: the purpose of painting is to isolate the surface as much as possible steel pipe from water vapor and oxygen.

The list of binders used in exterior paints is also relevant here. Separately, I would like to introduce a class of coatings that is directly related to safety of use. gas equipment— . What it is?

This is the name for coatings that swell when heated and turn into carbon foam, which has excellent thermal insulation properties and can withstand flames for a long time. Thus, fire-retardant paints for metal Polistil can protect metal base for at least 45 minutes.

Painting technology

Is it difficult to paint a gas pipe with your own hands?

The instructions for painting are no different from those relevant for any other metal product - with one caveat: when stripping the old coating, you cannot use heat.

1. The pipe section is wrapped in a rag soaked in detergent. After 10-15 minutes, softened paint.
2. Then the pipe is cleaned with a wire brush. The goal is to remove residues old paint and rust.

1. The surface is degreased. The easiest way to do this job is with a rag soaked in solvent or gasoline.
2. Paint or varnish is applied in two layers with intermediate drying. No more than six hours should pass between cleaning the corroded surface and painting: atmospheric humidity will very quickly cause the steel to become covered with a layer of new rust. The tool is a regular brush.

Conclusion

The video in this article, as usual, will delight the reader with an abundance of additional information on the topic we are discussing. Good luck!
