How to paint a gas pipe in an apartment. Painting Gas Pipes

In our homes, it’s common to have communication pipes. And if some of them can be closed, for example, in a box from gypsum board, then with the gas pipes this number will not pass.Gas services require that their communications were open, so you can detect gas leaks and take action.

There are, of course, ways you can get around this rule, such as hiding the tubes behind a removable grate. But mostly gas pipes. open. A rusty pipe in the middle of a renovated room doesn’t look very spectacular, so something needs to be done, and more specifically, paint the gas pipe.About paintsPaint gas pipes, as well as any other metal surfaces, alkyd paint. It looks different from any other paint because alkyd paint is more viscous and dense. This is because such paint is made of resin. Firstly, it is fire dangerous; Secondly, if such paint gets on the skin, it will not be cleaned with soap and water; Thirdly, alkyd paint has a very specific smell, so the room where the painting is done, should be well ventilated.But also advantages at alkyd paint plenty, it is very durable, and besides it can be put and on hot pipes. In the cold season, such a paint can be used, but there is a chance that it will freeze faster than dry. So if you are going to work outdoors, it is better not to do it in the bitter cold.We are all used to seeing yellow gas pipes in the street, it is also a requirement of gas workers. But there is a reservation, if the pipes are on the facade of the building, they can be painted the same color as the facade. In an apartment, you can paint the pipes any color you want. Due to the fact that the gas pipe is open, it can be painted in the color of the interior, so it is not conspicuous. Although the more traditional color is white.There are paints that can be applied directly to the rust. But still, before you paint your gas pipes, you need to make the necessary preparations. The pipe must first be sanded and the old paint must be partially or completely removed, then degreased. Do not be lazy to do this, and then the pipe will turn out flat, smooth and look quite nice.How paints behave when paintingCarry a small brush, and to avoid leaks, it is better to apply it in small doses and perpendicular to the pipe. If the pipe runs along the wall, you can bend the brush to paint the back. But in any case it is better to paint before the walls will be further finishing, because it is very difficult to remove alkyd paint, for example, from wallpaper. If one time you do not get a good color marking on the pipe, you can repeat the process after waiting a certain amount of time, sometimes 4-6 hours, and sometimes 24 hours, depending on the manufacturer.Such paint is also called radiator paint, that is suitable for heating radiators. You can also often find a paint with the name PF-115, this is the name according to GOST. Many manufacturers produce this paint.

How to paint gas pipes: the choice of color and type of coating

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

  • Color identification of the pipeline in the conditions of industrial plants, gas boilers, etc.д. Agree, it is much easier to determine the functionality of the pipe by color than to raise the documentation for the junction in front of you.

Important: as we will see further, the color marking is only used in industrial conditions or on the ground, when laying aboveground gas pipelines. Any requirements of the local authorities about the color of the pipe on the facade of the house or inside it is illegal.

Color coding is required primarily in industrial environments.

  • Corrosion protection. Because the environment inside the pipe is devoid of oxygen and water vapor, its service life depends exclusively on the corrosion resistance of the outer coating.

So what color should gas pipes be?

  • Aboveground gas pipelines are painted with two coats of yellow lacquer, enamel or paint. The coating must be intended for exterior use. The color coding is for identification purposes.
  • Exterior gas pipes that run along the facade can be painted to match the color of the building envelope.

The choice of color for gas pipes inside apartments and private homes is not regulated at all.

Why it is necessary?

Painting gas pipes is not an aesthetic matter. It is required in order to:

Identify by the color of the gas pipeline, not to confuse it with other types of pipes. Especially it is necessary on the industrial enterprises, in boiler rooms. Naturally, by the appearance and color of the pipes, the right fishing line is much easier to determine, as opposed to having to study all the documents for unbundling.

An important nuance should be called that the marking of gas pipes by color is necessary only for industrial enterprises or when laying a gas pipe above ground. There are no requirements of the authorities for residential premises, both inside and outside.

GOST 14202-69 clearly states in what color gas pipes must be painted. Thanks to this emergency service will be able to quickly find the source of potential danger and eliminate it, allowing to avoid tragic emergencies. In addition, with the help of quality paint can reliably protect metal pipes from corrosion.

Paint choice

Paint for painting gas pipes in the home or outdoors is also chosen according to certain requirements.

Its main purpose is to prevent the corrosion of metal conduits, but there are differences between the compositions for indoor and outdoor use.

There are, of course, ways to get around this rule, such as hiding tubes behind a removable grid. But mostly gas pipes are open. Rusty pipe in the middle of the renovated room does not look very impressive, so you need to do something, and more specifically. to paint the gas pipe.

Paint gas pipes, as well as any other metal surfaces, alkyd paint. In appearance, it differs from any other paint in that alkyd paint is more viscous and thicker. This is because such paint is made of resin. Work with it needs to be extremely carefully:

Firstly, it is flammable; Secondly, if such paint gets on the skin, it will not be cleaned with soap and water; Thirdly, alkyd paint has a very specific smell, so the room where the painting is done, must be well ventilated.

But the alkyd paint has a lot of advantages, it is very durable, and in addition it can be applied to hot pipes. You can use such paint in the cold season, but there is a chance that it will freeze faster than it will dry. So if you are going to work outdoors, it is better to do it not in a fierce cold.

We are all used to seeing gas pipes in the street in yellow color, it is also a requirement of gas companies. But there is a caveat, if the pipes go along the facade of the building, they can be painted in the color of the facade. In the apartment, you can paint the pipes in any color you want. Due to the fact that the gas pipe is open, it can be painted in the color of the interior, so it is not conspicuous. Although the more traditional color is white.

There are paints that can be applied directly to the rust. But before you paint your gas pipes you still need to make the necessary preparations. The pipe must first be sanded, remove part or all of the old paint, and then degrease. Do not be lazy to do it, and then the pipe will turn out flat, smooth and will look quite nice.

color, paint, pipe

Paint a small brush, and to avoid leaks, it is better to apply it in small doses and perpendicular to the pipe. If the pipe goes along the wall, the brush can be bent so as to paint the back part. But in any case it is better to paint before the walls will be further trim, because to remove alkyd paint, for example, with wallpaper is very difficult. If one time the tube is not well painted, you can repeat the procedure, waiting a certain amount of time, sometimes 4-6 hours, sometimes a day, depending on the manufacturer.

Such a paint is also called a radiator, that is suitable for heating radiators. You can also often find a paint with the name PF-115, this is the name according to GOST. Many manufacturers produce such paint.

Communications in apartments and houses is a common phenomenon. Some of them can be hidden behind gypsum board. And here are special requirements for gas pipes, as their condition affects the welfare and lives of people.

Agree that the operation of gas utilities should be treated with the utmost responsibility. Paint for gas pipes must be chosen with special care, because its task is to protect the steel alloy from corrosion. However, gas pipes painted to a common standard can disfigure the interior.

We’ll tell you when regulations are mandatory and when they can be neglected. You will learn how to choose paint for gas utilities and conduct the basic steps of painting. As a bonus, we’ll tell you the secret of how to calculate the exact amount of paint you need.

The regulatory colors of the painting of the pipeline

Good day to all of our regular readers and colleagues! The topic of our article today. the regulatory colors of the painting of the pipeline. The purpose of the topic. how to accurately determine the color in which to paint the pipeline of various systems, depending on the purpose of the pipeline.

In the list of engineering systems of buildings and constructions, quite often, there are such systems as fire plumbing, fire drencher or sprinkler systems, gas or aerosol fire extinguishing systems. As a part of the above systems, there are pipelines supplying fire extinguishing agents to the place of fire. Pipelines are often located under the ceiling, often in the overhead space and it would be impossible to determine which pipe in the mass of the pipeline from which system, if the pipes were not labeled. These very pipelines should be painted in signal colors, defined by GOST, so that one could identify in advance what substance is in the pipe. water, gas, compressed air or the pipe is just a dry pipe. Specific regulatory colors of the pipeline color are provided in GOST 14202-69 “Pipelines of industrial enterprises. Identification, Warning Signs and Labels. You can download this document in full from our site in the library of regulatory documents, as usual for free and without any SMS, simply by following this link 1646-gost-14202-69. The document is valid, although it has been in force since 1971, i.e.е. In the Soviet Union, reference to this GOST is in the list of normative references in the codes (in particular SP5.13130-2009), and fire inspectors often pay attention to the execution of this document.

The essence of the requirements of GOST. the regulatory colors of the painting of pipelines, warning signs, markings of pipelines. GOST establishes the following ten aggregated groups of substances and colors depending on these substances:

  • Water. green
  • Steam. red
  • Air. blue
  • Combustible gases (including liquefied gases). yellow
  • Non-combustible gases (including liquefied gases). yellow
  • Acids. orange
  • Alkalis. violet
  • Flammable liquids. brown
  • Liquids that are not flammable are brown
  • other substances. grey

In addition to the standard colors of the pipeline color scheme, the following color rings in the following lists and colors are additionally applied to mark the substances in the pipelines most hazardous for their effects on people

  • Flammability, flammability and explosiveness. red
  • Dangerous or harmful (poisonous, toxic, asphyxiant, burnable, radioactive, high pressure or deep vacuum). yellow
  • Safety or neutral. green

The number of rings to be applied is limited from one to three, depending on the degree of hazard of the substance (the more hazardous the more rings). In addition, in some cases stipulated by GOST, the pipeline is additionally marked with triangular warning signs and marking shields.

There are on sale ready-made pipeline linings that are convenient to use for marking purposes in the following form, which does not actually exclude, but complements the regulatory colors of the painting of the pipeline :

In addition, paragraph 5 of the above GOST 14202-69 reads literally as follows:

Fire fighting pipelines irrespective of their contents (water, foam, fire fighting steam, etc.).), sprinkler and deluge systems at the sections of shut-off and control valves and hose connections, etc. fire extinguishing devices must be painted red (signal color).

Pay special attention to the form of the above norm, because many installation companies, without carefully reading the above paragraph, simply paint the entire pipe in red, as the pipeline is part of the fire protection systems. This is not correct. the red color only in the areas of shut-off valves and connections of fire hoses. In other places, the normal colors of the painting of the pipeline, in accordance with GOST, are given above.

Painting of gas pipes

In our houses, the usual phenomenon. pipe communications. And if some of them can be closed, for example, in a box made of gypsum plasterboard, this number will not pass with the gas pipes. Gas services require their communications to be open, so you can detect gas leaks and take action.

There are, of course, ways you can get around this rule, such as hiding the tubes behind a removable grill. But mostly gas pipes are open. Rusty pipe in the middle of the renovated room does not look very impressive, so you need to do something, and more specifically. to paint the gas pipe.

Gas pipes are painted like any other metal surface with alkyd paint. It looks different from any other paint, because alkyd is more viscous and thick. This is because such paint is made of resin. You have to work with it very carefully:

Firstly, it is flammable; Secondly, if such paint gets on the skin, clean up with soap and water will not work; Thirdly, alkyd paint, has a very specific smell, so the room in which the painting is done, should be well ventilated.

But there are also many advantages of alkyd paint, it is very durable, and in addition it can be applied to hot pipes. During the cold season it is possible to use such paint, but there is a probability that it will freeze faster than it will dry. So if you are going to do exterior work, it is better to do it not in the bitter cold.

We are all used to seeing gas pipes on the street in yellow, this is also the requirement of gas workers. But there is a caveat, if the pipes go along the facade of the building, they can be painted in the color of the facade. In the apartment, you can paint the pipes any color you want. Due to the fact that the gas pipe is open, it can be painted in the color of the interior, so it is not conspicuous. Although the more traditional color is white.

There are paints that can be applied directly to the rust. But still, before you paint gas pipes, you need to make the necessary preparations. The pipe must first be sanded, remove part or all of the old paint, and then degrease. Do not be lazy to do this, and then the pipe will be flat, smooth and look quite nice.

Paint with a small brush, and to avoid leaks, it is better to apply it in small doses and perpendicular to the pipe. If the pipe goes along the wall, the brush can be bent so as to paint the back part. But in any case, it is better to paint before the walls will be further finishing, because it is very difficult to remove alkyd paint, for example, from the wallpaper. If you can not paint the pipe well from one time, you can repeat the procedure, waiting a certain amount of time, sometimes 4-6 hours, and sometimes a day, depending on the manufacturer.

Such paint is also called radiator paint, that is suitable for heating radiators. Even often there is a paint with the name PF-115, this name according to GOST. Many manufacturers produce such paint.

Formula for calculating the amount of paint

Figuring out what to paint gas pipes, you need to calculate the amount of paint. There are no standards for paint consumption for coating gas pipes. On each can, the manufacturer indicates how much material is required to paint 1 sq. м. surfaces.

How to Paint Rusted Natural Gas Pipes

Note that the application must be made in two layers. Formula for calculation:

This method is used in painting most pipelines.

With the criteria for selection and the best heat-resistant paint compositions for coating the metal will introduce the following article, which is described in detail all aspects of the question.

Preparation

The choice of painting method and type of paint depends on the material from which the pipes are made, as well as the conditions in which they are used. For example, outdoor utilities should be painted with lead sulfuric acid, which creates a mask of iron oxide and lead on the surface. This mask can protect pipes from the damaging effects of the environment.

For the painting of pipelines are usually used the following products:

Acrylic enamel is resistant to high temperatures (up to 1000 degrees). It is also resistant to significant temperature fluctuations. The advantages of water-dispersion paint are fast drying speed, high quality of adhesion to the surface and environmental friendliness. Pipes painted with waterborne 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 designed for the hot surface.

Acrylic enamel has the ability to retain color for quite a long time (it is resistant to UV 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 the treatment of almost all types of pipes. However, over time, the original color is lost.

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

For painting, we will need the following:

  • brush;
  • paint;
  • sandpaper;
  • gloves;
  • rag;
  • primer;
  • cuvette;
  • a ladder (if working at height).

Before you start to paint, it is desirable to clean the surface of the pipes from the old paint. After that, it is necessary to carefully sand the surface with sandpaper. There must not be any rust. All cracks and irregularities should be repaired with putty. Before you paint plastic pipes, you need to wash them with warm water. After that, you need to give them time to dry.

You can not remove the old paint if the surface of the pipe has no defects: damages, bulges, cracks. Otherwise, it is better to remove the old paint coat.

Now determine how much paint is needed. Here are some recommendations on this:

  • For hard-to-reach areas, you will need a larger amount of paint.
  • The first coat needs more paint than the second coat.
  • The flat surface needs less paint than the rough surface of the same area.
