Paint for gas pipes: rules and regulations for painting inside the apartment and on the street

What do we paint them with?

For enlarged pipeline groups, there is an identification color, as well as digital marks.

The color designation of pipelines according to Table 1 from the above-mentioned GOST looks like this.

According to clause 5, in all cases, the colors of fire protection pipelines, as well as sprinklers, drenchers,

other fire-extinguishing agents at hose connections and shut-off valves must be painted RED only.

And here many stumble and paint the whole product red. This is the wrong approach.

Painting fire pipelines in a red tint is carried out only in the areas of constipation and butt joints.

In other areas, we focus on standard values ​​- the color of pipelines according to GOST is indicated in the list above.

Condensation control

Condensation on pipes is a fairly common problem. It becomes especially relevant in the summer, when the air in the apartment is hot enough. Drops of water flowing down the water pipes, gradually forming whole puddles on the floor, cause a lot of trouble.

Condensation can be dealt with in various ways. Before proceeding directly to getting rid of the problem, it is necessary to establish the cause of its occurrence.

Condensation on metal pipes can form as a result of:

• Poor ventilation performance
• Leaks in neighbors pipes
• Faucet leaks and other plumbing problems

As a rule, the formation of condensate on pipes is associated precisely with temperature differences. It is not possible to avoid them. However, it is possible to ensure proper protection of pipelines by following certain procedures.

Methods for dealing with condensate on pipes:

1. First of all, you need to make sure that the bathroom is adequately ventilated. The normal level of humidity in the room is considered to be up to 50%. If necessary, consider installing exhaust ventilation in the room. At the end of the water procedures, you need to leave the door to the bathroom open.
2. It is also necessary to take care of eliminating the leakage of the flush tank, faucet. Repair of plumbing equipment is one of the options for solving the issue of combating condensate.
3. A fairly simple and effective way to solve the problem is to wrap pipes with rags and apply epoxy putty. The methodology for implementing the work is as follows. The pipe is pre-cleaned from traces of rust with sanding paper, then degreased with acetone.Next, the first putty layer is applied and the pipe is bandaged with fabric, which ensures epoxy impregnation of cold water pipelines. After the epoxy hardens, a second putty layer is applied. This method demonstrates sufficient efficiency and economy. However, it spoils the appearance of the entire bathroom, which is why it is not very popular today.
4. The most effective and modern way to get rid of the problems of condensate formation on pipes is the creation of a special coating. A couple of decades ago, the post-Soviet space could not imagine such a convenient thing as heat-insulating paint. Today you can buy it at a regular hardware store. Such thermal paint will most effectively solve the problem of moisture formation on metal pipes. Buying this paint, you should give preference to trusted manufacturers with a decent reputation. Thus, you will save your money. Akterm's products have managed to win the recognition of consumers. Acterm Anticondensate is a special product designed to solve the problem of condensation formation as a result of a sharp temperature drop on metal surfaces. The use of such thermal paint serves as an obstacle to the appearance of condensate on cold water pipelines, which prevents the occurrence of fungus, mold, rust and freezing on their surface. The product is non-toxic and completely safe for human health.

Using this option to deal with condensate, you can significantly extend the life of your pipes.Thermal paint does an excellent job of solving the problem of an insufficient layer of thermal insulation and reducing the heat-shielding qualities of the insulation, which are the main causes of condensation on metal pipes and surfaces.

Color solution

What color to paint the gas lines?

According to the source of information (Safety Rules for the gas distribution system), painting occurs as follows:

1. The gas pipeline passing above the ground must be painted with two layers of yellow paint. Lacquer and enamel of the same color is also allowed. The coloring matter must meet the requirements of the substance for working outside the product. Color marking is necessary to identify the object.

2. The gas system that runs over the facades of the structure may have the color of the structures that enclose it.

Painting of internal gas pipeline structures inside residential premises and the color scheme for them are not provided at all.

Owner Search

Who is responsible for painting the gas pipe? Many people ask this question. Unfortunately, the person responsible for such a process in each individual case has to be found separately. In such cases, it is necessary to be guided by the maintenance contract for the gas pipeline.

In certain areas, responsibility is distributed in this way:

1. In apartment buildings, pipeline lines inside each apartment must be painted by the owners of the apartments. Those gas pipes that run along facades, porches or streets must be painted by the gas supply companies or the local utility (the terms of the service contract should contain such obligations).To separate the zone, you must be guided by the walls of the apartments

It must be taken into account that such duties relate only to painting pipes. But maintenance actions regarding the shut-off elements of valves should be performed only by the gas service. 2

In private houses, the gas pipeline located on a private plot is painted by the owners of the house. The gas pipeline located on a public site is painted by representatives of the gas service. The gas pipeline that runs through the private territory of the house may be controlled by the organization that supplies the gas, but then such an authority may require the owners of the houses to pay for the service of painting gas pipeline structures

• 2 Painting
• 3 Painting gas pipes

It is impossible to imagine modern residential buildings and industrial facilities without all kinds of communications: water pipes, gas pipelines, cables, and so on. Nowadays, many pipelines (for example, cold and hot water supply) are made of plastic. However, metal pipes continue to be used.To increase the service life and to improve the appearance, these pipelines need to be painted.

As a rule, the reasons that prompt the decision to paint pipes are:

• Unsatisfactory condition of the pipe surface.
• Corrosion protection.
• Improving the interior of the room.

Training

The choice of painting method and type of paint depends on the material from which the pipes are made, as well as on the conditions of their operation. For example, outdoor communications should be painted with red lead, due to which a mask of iron oxide and lead is formed on the surface. This mask is able to protect pipelines from the damaging effects of the environment.

The following products are commonly used for painting pipelines:

• alkyd enamel;
• water-dispersion paint;
• acrylic enamel;
• Oil paint.

Acrylic enamel is resistant to high temperatures (up to 1000 degrees). It is also resistant to significant temperature changes. The advantages of water-dispersion paint are fast drying speed, high quality adhesion to the surface and environmental friendliness. Pipes painted with water-dispersion paint can be used for many years. Such paint, in turn, is divided into two types: for cold and hot surfaces. That is, painting heating pipes will require the use of paint intended for a hot surface.

Acrylic enamel has the ability to retain color for quite a long time (it is resistant to ultraviolet rays). In addition, this paint makes the surface glossy. Before using this type of paint, the surface must be treated with a primer.And finally, oil paint is suitable for processing almost all types of pipes. However, over time, the original color is lost.

For example, for painting a rusty metal pipe, it is best to use enamel group paints. After a day, the painted surface will be dry. Such paint will protect the pipe from corrosion for 7 years. For plastic pipes, water-based or oil paint is the best option.

For painting we need the following:

• brush;
• dye;
• sandpaper;
• gloves;
• rag;
• primer;
• cuvette;
• ladder (when working at height).

Before you start painting, it is advisable to clean the surface of the pipes from old paint. After that, you need to carefully clean the surface with sandpaper. There shouldn't be any rust. All cracks and irregularities must be eliminated with putty. Before painting plastic pipes, they must be washed with warm water. After that, you need to give them time to dry.

Old paint can not be removed if the pipe surface has no defects: damage, bulges, cracks. Otherwise, it is better to remove the old layer of paint.

Now we determine how much paint is required. Here are some recommendations for this:

• For hard-to-reach places, you will need more paint.
• The first layer needs more paint than the second.
• A smooth surface will require less paint than a rough surface of the same area.

Painting

Before painting, it is recommended to protect the floor under the pipes with foil or newspapers. We start painting from the top of the pipes and move to the bottom. So the layer will be uniform. We apply the first coat of paint to the entire surface - do not miss anything.Only after applying the first layer on the entire surface can the second one be applied. Applying two layers allows you to get a perfectly painted, even surface.

How to quickly paint pipes? To save time, you can use a spray can or spray gun. In addition to saving time, this will give us a quality painted smooth surface. When working with a spray can, you need to keep it at a distance of 30 cm from the surface and make zigzag movements from top to bottom. When using an airbrush for painting the battery, it is recommended to remove it in order to qualitatively process all hard-to-reach places.

After painting, it is necessary to wait a certain time for the paint to dry and thoroughly ventilate the room.

What is it for?

Painting gas communications is far from an aesthetic matter. This is required in order to:

1. Determine the color of the gas pipeline, do not confuse it with other types of pipes. This is especially necessary in industrial enterprises, in boiler houses. Naturally, by the external features and color of the pipes, it is much easier to determine the desired line, in contrast to studying all the documents for decoupling.

An important nuance should be called the fact that it is necessary to mark gas pipes by color only for industrial enterprises or when laying a gas pipe above the ground. There are no government requirements for living quarters, both inside and outside.

2. Create protection against corrosive formations. Since there are no oxygen accumulations and water vapor inside the pipe, the long-term operation is directly dependent on the level of resistance to corrosive formations of external surfaces.

What is, how it differs from traditional insulation

In recent years, energy prices have been constantly rising, and the issues of economical heating are directly related to the maximum insulation of premises and, of course, to the choice of the most efficient heaters. Today, manufacturers offer a wide range of traditional heaters that require serious preliminary work during installation and additional materials, without which high-quality and aesthetic insulation is impossible. But along with the traditional technologies of additional insulation, the emergence of an innovative material on the market - heat-insulating paint, which in some cases can be much more effective, aroused great interest.

The use of heat-insulating paint for the exterior walls of the house

Thermal insulation paint is a modern universal ultra-thin thermal insulation that prevents heat loss, with the functions of protecting against fire, fungus and mold. Innovative developments have made it possible to bring to the market a product that forms a thin layer of the front surface of walls with a level of protection equal to foam plastic and basalt wool up to 50 mm thick. But we must remember that the issue of additional insulation and stabilization of the microclimate in the premises of an already insulated house is being resolved here.

The paint is produced in two versions: with a water and acrylic base, has a liquid or pasty consistency, which contributes to uniform application and better adhesion to the treated surface.Liquid heat-insulating paint is produced to cover different surfaces, for different operating conditions, with a filler in the form of gas-filled ceramic nano granules, with additives of latex or silicone, substances that increase the water resistance and elasticity of the mixture.

Important: When choosing liquid thermal insulation, you should pay attention to the annotation, which indicates the areas and conditions of use, as well as all the main performance characteristics!

In order to insulate the house from the outside or from the inside with mineral wool and foam plastic, it is necessary to purchase additional materials, mount a wooden or metal profile frame, install insulation and sheathe it with decorative materials inside, and install moisture-resistant finishing material (siding, lining) outside. This requires additional costs for the work of craftsmen and the purchase of materials, but all the difficulties of such insulation can be avoided.

The use of heat-insulating paint for the exterior walls of the house

It is enough to use a unique heat-insulating paint with a composition that makes it an indispensable tool for warming various surfaces. The advantage is that liquid insulation can be applied independently using a special sprayer and brush in inaccessible places. At the same time, the composition of the paint is so plastic that it lies very evenly even under a non-professional roller. Heat-insulating paint has the property of visually compensating for irregularities and covering microcracks and interacts well with pigment dyes. But not every manufacturer.

In order not to fall for low-quality products or fakes, it is necessary to determine the quality, and for this, keep in mind the following features of nanopaint:

• the presence of ceramic microgranules with voids reduces weight with a large volume, so a bucket of paint with a volume of 10 liters weighs only 6 kilograms;
• the presence of ceramic microgranules is easily determined by touch, numerous hard grains are felt under the fingers;
• during long-term storage, the mixture separates and a significant layer of microgranules forms at the bottom.

Attention! Before starting work, thorough mixing and regular mixing during work are required.

» Miscellaneous » What paint to paint the gas pipe in the apartment

Before you start painting the gas system, it is necessary to polish it from the old coating layer or rusty inclusions. Next, you need to free the pipes from dust accumulations and pollution. After that, the gas pipes must be covered with a soil material designed specifically for metal products. But after all the work done, they begin to paint communications.

According to the requirements of the state standard, gas lines must be highlighted with yellow paint. This is done in order not to confuse the gas networks with other pipes in the room. It is allowed to paint with any type of paint that is suitable for metal products and is suitable for both external and internal work.

how to paint a gas pipe in a house

Previously, the pipes on the street were painted red. The pipes located in the room, in most cases, acquired the color that suited the interior or liked the residents.Pipes in the room can be painted with inexpensive paint, while saving money. It will keep for a long time.

But, if the gas system passes on the street, then it is necessary to choose a coloring matter that can ensure the long-term coverage. And it’s better if you first clean the pipes from rusty formations, prime them, and only then paint them, so the coating layer will last longer.

Material selection

When choosing a primer, you need to be careful

You need to pay attention to what is written on the can, the primer should be purchased one that is suitable for application over rusty areas

In addition, ground liquid also comes in several versions, namely different colors, from black to green and blue. Having made a choice of color, it is necessary to calculate the desired volume.

It is recommended to buy using this formula one liter of varnish and two liters of ground liquid. Lacquer should be purchased one that is suitable for covering metal products with it.

This is necessary so that, due to the porosity of the ground fluid, a moist environment does not get on the metal pipe, as rusty spots will subsequently form.

For this reason, it is worth adding a good quality varnish to the ground mass, which will ensure:

1. Pores will not form;

2. Will not rust;

3. Pipes will have a glossy appearance for a long time.

After the choice of materials is made, it is necessary to mix them and before applying the mixture to the surface of the pipe, it is necessary to wipe the pipes with a coarse sponge. Then, lubricate the gas line evenly, without missing a single centimeter. This can be done directly on rusty places.After performing such work, it will immediately become clear how the appearance of the gas system will change.

Of course, it is worth paying attention to special types of paints that are designed for metal products. Before buying, you need to familiarize yourself with the information on the label of the jar, it should be written there, for example, it has anti-corrosion properties, it is intended for metal products, it may have an inscription 3 in 1

how to paint a gas pipe

In addition, it can quickly ignite, so when choosing on it, you should be careful. The main thing is that from the information received it can be concluded that the coloring matter will transform the rusty sections of the pipes, then the painted layer of the gas line will last for a long time.

In accordance with building codes and regulations, colorants and varnishes are used that can withstand the temperature fluctuations of the environment and the influence of rain, snow, hail and other things.

The main thing to remember is that the coloring matter must be one of the types of oil or nitro enamel waterproof products. The surface of the pipe must be painted yellow, the valve may be painted blue.

how to cover a gas pipe The state standard determines the colors of pipe staining, depending on the transported liquid:

1. Pipes transporting water are painted green;

2. In the steam system, the pipes must be painted red;

3. Air ducts in blue;

4. Yellow color is defined for gas lines;

5. Networks carrying acid should be orange;

6. Alkali supply wire purple;

7.Lines supplying liquids, both flammable and non-flammable, must be brown;

8. Pipelines transporting other substances have a gray appearance.

Paint for metal products can be found in any building department.

Technological features of staining

Many people think about whether it is possible to paint the gas system on their own? Wouldn't it be difficult?

The stages of painting, in general, do not differ from the procedure for painting any metal pipe, but having one nuance: in the process of cleaning from the old layer of paint, it is forbidden to use
.

1. A piece of the product must be wrapped in a rag, after soaking it with a wash. After 20 minutes, use a spatula to remove the softened paint.

3. Apply a degreaser over the pipes. For these purposes, gasoline or solvent is suitable.

4. Apply colorants in two layers, be sure to dry before the layers. The time interval between cleaning and painting should be about six hours, since the humidity of the air will quickly contribute to rusting steel products. For these purposes, use an ordinary brush.

conclusions

Knowing all the listed nuances of painting gas pipelines, it is possible to successfully ensure their long-term coverage.

Of all the "utilities", gas is the most "nasty". Let's omit the cost of connecting to gas networks, which does not look justified at all. The gas pipeline can run right along the border of the site, but you will be charged more than a thousand dollars for the “connection” of two meters of pipes. 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 appliances inside the house. Needless to say, both the design and installation of this gas pipeline are carried out by “licensed” enterprises that also want to eat, and eat well. In general, the situation when the seller of goods 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 milk to you in the morning.

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

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

Not the most aesthetic option.

We take DBN V.2.5-20-2001, Gas supply. Reading. We find that “gas distribution points” are painted yellow, and not low-pressure gas pipelines for residential buildings. The 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, plus the type of coloring material (which is logical - the gas pipeline must be protected from corrosion), are established, but not the color. So the requirements to disfigure your facade can be safely ignored.

The next interesting point is the ban on the "concealed installation" of the gas pipeline indoors.According to the interpretation of 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 I was told this for the first time, I simply brushed it aside, but during the installation process I was persistently accustomed to 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 again in the same DBN, after which it turned out that the hidden installation of the gas pipeline is an absolutely permissible thing, you just need to provide access to it using any 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 interest to smell it as quickly as possible so that the gas does not accumulate in an enclosed space.

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

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

Temperature ranges

At what temperature is the use of special, heat-resistant primers required? Let's analyze the coating requirements for different operating temperatures.

Up to 60C

In this temperature range fit, in particular, elements of autonomous heating systems. Typical for them, the temperature difference between supply and return is 70/50C, which gives no more than +60C on the surface of heating devices.

At temperatures from 0 to +60, general-purpose paints and primers can be safely used.Subject to the painting technology (that is, with high-quality cleaning of the surface and the conformity of the soil to the type of paint and varnish material), you can not be afraid of delamination or fading of the paint.

General purpose paints can be used in an autonomous heating circuit.

Up to 100C

The only significant difference from the previous scenario is the need to use paints with persistent pigments. The binder and primer remain the same as before: all popular types of paints tolerate prolonged heating without destruction.

Up to 300C

And here comes the finest hour of heat-resistant soils. If the instruction for the use of temperature-resistant paintwork materials contains an indication of the need for priming, you will have to select special compounds that tolerate prolonged heating and retain their properties over the entire range of operating temperatures.

Over 300С

All paints intended for temperatures above +300 degrees are applied without preliminary priming, directly on a cleaned and degreased surface. A layer of soil at such temperatures will only increase the likelihood of delamination of the coating.

Particularly heat-resistant paints are applied directly to the metal base.
