When carrying out construction, installation and other special work, a special place is occupied by the laying of main steel pipelines.
All communications are divided into 10 main groups in relation to the substances that they transport, and therefore there is a need to identify and mark linear routes.
Labeling in Russia has passed the stage of standardization, requiring the mandatory application of GOST standards. Failure to comply with the rules is punishable by law, and also threatens the population with accidents, injuries, disruption of the production cycle, and man-made disasters.
Color marking of pipelines
Pipelines are marked with the appropriate color, numbers, warning signs, and special shields, which allows even an inexperienced specialist to determine the contents and degree of risk of linear systems.
Color gradation when marking pipelines
The color marking of pipelines corresponds to GOST 14202-69. According to this rule:
- green color corresponds to group 1, transports water;
- red color corresponds to group 2, transports steam;
- blue color corresponds to group 3, transports air;
- yellow color corresponds to 4-5 groups, transports flammable and non-flammable gases;
- orange color corresponds to group 6, transports acids;
- purple color corresponds to group 7, transports alkalis;
- brown color corresponds to groups 8-9, transports flammable and non-flammable liquids;
- gray color corresponds to group 0, transports other substances.
Important! Fire protection systems, regardless of the internal component, are always painted in the signal red color. If necessary, they additionally use other means of notation.
Requirements for dyes
Marking of pipelines taking into account all characteristics
The color used to apply distinctive signs must be resistant to chemicals and weather conditions, since marking communications is necessary both in the industrial sector and in residential complexes. GOST 14202-69 does not apply to electrical wiring networks.
There are several ways to apply paint to systems.
The continuous painting method is applied if the pipeline is short and consists of a small number of connections.
If there are a large number of components of wired networks, long kilometers, and also if the architecture of the building does not imply large areas of painting, painting in separate fragments is used. The rest of the pipeline is colored to match the color of the walls, ceiling, floor, etc. In the case where communications are located outside buildings and structures, the color should reduce the thermal effect on the pipes.
The size of the coating also depends on the outer diameter of the pipes. If the diameter is large, the color designation is applied in the form of stripes with a height of at least 1/4 of the pipe circumference.
According to GOST, paint is applied to the most important and critical areas, for example, at the places of connections and passage of pipes through walls, ceilings, floors, etc., at flanges, at points of sampling and instrumentation, in the area of entry and exit to the room and from it after 10 - meter sections inside the building and every 30-60 m outside.
All pipeline marking data in the table
Important! On pipelines with increased pressure, connecting flanges must be painted, since the linear systems themselves are in protective casings.
Marking of communications with various devices
In the case where the contents of communications are particularly aggressive in nature, warning rings are applied to them in one of three colors: red color corresponds to flammability, flammability and explosion hazard; yellow color - danger and harmfulness (toxicity, radioactivity, ability to cause various types of burns, etc.); green with a white border indicates the safety of the internal contents. The width of the rings, the distance between them, and application methods are standardized by GOST 14202-69.
Network marking is possible using stickers. In the case when the sticker contains text, it is written in a clearly legible font, without unnecessary symbols, words, abbreviations, in the most accessible syllable. Fonts comply with GOST 10807-78.
The stickers are also made in the form of arrows showing the direction of flow of the substance inside the pipe. The hands are also standardized in terms of size. The designation on the arrows is differentiated: “flammable substances”, “explosive and fire hazardous”, “toxic substances”, “corrosive substances”, “radioactive substances”, “attention - danger!”, “flammable - oxidizer”, “allergic substances” " The color of the arrows, as well as the inscriptions, is applied in black or white to achieve the greatest contrast with the main coating of the pipe.
For particularly dangerous components of communications, stickers are made in the form of warning signs (in addition to color rings). The signs are triangular in shape with a black image on a yellow background.
Important! In hot water supply systems and in the case of transporting leaded gasoline, the inscriptions must be white.
If the contents of the pipeline can damage the color designation or change its shade, special shields are used as additional markings, which are informative in numbers and letters. The requirements for shield graphics are identical to those for decals. The dimensional characteristics of the shields correspond to the characteristics of the arrows. Marking panels must be located in clearly visible places and, if necessary, illuminated with artificial lighting without interference for viewing by maintenance personnel.
Types of coatings
To cover linear systems, a paint and varnish material is used that complies with GOST and depends on the internal component, the physical and chemical composition of the pipes, their insulating characteristics, as well as the cost of the paint.
In rooms where there is no aggressive environment and good ventilation, it is possible to use enamels in accordance with technical documentation.
The application of markings must be carried out strictly in accordance with safety regulations in order to avoid accidents and injury.
Periodically, all marking products must be updated to restore the original color.
High-quality and timely marking of main pipelines is not only safe, but also economically beneficial due to the absence of accidents at serviced facilities. And the use of state standards will also protect the enterprise from criminal or administrative liability.

VII. Painting and markings on pipelines
7.1. Depending on the purpose of the pipeline and environmental parameters, the surface of the pipeline must be painted in the appropriate color and have markings.
Coloring, symbols, letter sizes and placement of inscriptions must comply with state standards.
7.2. The following inscriptions must be applied to pipelines:
a) on main lines - the number of the main line (in Roman numerals) and an arrow indicating the direction of movement of the working medium. If in normal mode it can move in both directions, two arrows are given, directed in both directions;
b) on branches near the main lines - the main line number (in Roman numerals), unit numbers (in Arabic numerals) and arrows indicating the direction of movement of the working medium;
c) on branches from the mains near the units - the number of the main (in Roman numerals) and arrows indicating the direction of movement of the working medium.
7.3. The number of inscriptions on the same pipeline is not standardized. The inscriptions must be visible from the control points of valves, gate valves, etc. In places where pipelines exit and enter another room, inscriptions are required.
7.4. When covering the surface of the pipeline insulation with metal casing (sheets of aluminum, galvanized iron and other corrosion-resistant metals), painting of the casing along the entire length may not be carried out. In this case, depending on the transported medium, appropriate symbols must be applied.

Identification painting of pipelines
Protective painting of pipelines is the main way to prevent corrosion and aggressive environmental influences on the pipe material. The main task of protective painting is to prevent contact of the pipeline with the environment throughout the entire range of operating parameters of the pipeline.
A completely different, but no less important function is performed by a mandatory element of pipeline marking - identification painting of pipelines. It is designed to quickly identify the substance transported through the pipeline and the degree of its danger.
Regulatory documentation for identification painting of pipelines
In each industry, there are a number of regulatory documents regulating the issues of identification painting of pipelines, however, all these documents either refer to or repeat the requirements of the main standard for identifying pipelines in the Russian Federation - GOST 14202.
This unification of markings makes it possible to unambiguously determine the contents of the pipeline at any facility - from a small modular boiler house to a nuclear power plant and an oil refinery.
Exceptions to which the requirements of GOST 14202 do not apply are pipelines with medical gases, ship and aviation pipelines.
Identification painting of pipelines involves color identification depending on the transported medium, as well as the application of warning rings that determine the degree of danger of the pipeline contents.
There are ten large groups of substances, each of which has a specific color (Table 1):
Often identification and protective painting are combined - a coating of the color that characterizes the transported medium is applied to the pipeline.
However, in many cases this is not possible, for example:
- - the protective coating required in specific conditions has a color different from that required by GOST 14202;
- - a heat-insulating structure is mounted on the pipeline;
- - the pipeline already has a factory protective coating;
- - the pipeline is made of non-ferrous metal and its painting is not required.
In these cases, the standard allows protective painting to be carried out not along the entire length of the pipeline, but in sections.
With this method, it is much more effective to use marking tapes of different colors. They are easier and faster to apply to the pipeline, and the durability and presentability of such markings are much higher.
The width of colored sections for pipelines with a diameter (including thermal insulation) up to 300 mm must be at least four diameters, and for pipelines with a diameter of more than 300 mm - at least two diameters. On pipelines of large diameters, painting may be applied in the form of strips with a height of at least ¼ of the circumference of the pipeline.
The intervals for applying identification painting to pipelines should be no more than 10 meters indoors, as well as in outdoor installations, and no more than 60 meters on external main pipelines.
Elements of identification painting must be applied at the passage of pipelines through walls and ceilings, in places where shut-off valves are installed, on inputs and outputs in buildings and installations.
More details on the requirements for identification painting of pipelines can be found in GOST 14202.

If it is necessary to apply yellow rings to gas (yellow) or acid (orange) pipes, their readability will be difficult. For this case, GOST 14202 provides for a black border with a width of at least 10 mm on the warning rings.
A similar requirement applies in the case of applying green rings to a pipeline with water (also green) - white borders with a width of at least 10 mm are applied along the edges of the rings.
Self-adhesive marking tapes, which, if necessary, may already contain borders of the required color, can simplify the work of applying colored warning rings to pipelines.
However, even more effective is the use of tapes that simultaneously have a background color corresponding to the group of the substance being transported and the necessary warning rings. In this case, the cost and speed of applying identification paint to pipelines is significantly reduced.
An example of pipeline marking with self-adhesive tapes
A mandatory element of identification painting is the placement in accessible places of the premises or site of the enterprise of diagrams and posters indicating the relevant requirements of GOST 14202.
To specify the substances transported through pipelines and their parameters, it is necessary to use markings or panels in accordance with the requirements of GOST 14202. The panels must contain the name of the substance, the direction of its movement, as well as the corresponding danger signs. The color, shape, size and font of the inscription must comply with the requirements of the above standard.

Color marking / coding / painting of general industrial pipelines (pipes). Regulatory documentation for identification painting of pipelines GOST 1402In each industry, there are a number of regulatory documents regulating the issues of identification painting of pipelines, however, all these documents either refer to or repeat the requirements of the main standard for identifying pipelines in the Russian Federation - GOST 14202.

Basic requirements for identification painting of pipelines
Identification painting of pipelines involves color identification depending on the transported medium, as well as the application of warning rings that determine the degree of danger of the pipeline contents. There are ten large groups of substances, each of which corresponds to a specific color (Table 1):

Often identification and protective painting are combined - a coating of the color that characterizes the transported medium is applied to the pipeline. However, in many cases this is not possible, for example:
- the protective coating required in specific conditions has a color different from that required by GOST 14202;
- a heat-insulating structure is mounted on the pipeline;
- the pipeline already has a factory protective coating;
- The pipeline is made of non-ferrous metal and painting is not required.
In these cases, the standard allows protective painting to be carried out not along the entire length of the pipeline, but in sections. The width of colored sections for pipelines with a diameter (including thermal insulation) up to 300 mm must be at least four diameters, and for pipelines with a diameter of more than 300 mm - at least two diameters. On pipelines of large diameters, painting may be applied in the form of strips with a height of at least 1/4 of the length of the pipeline circumference. The intervals for applying identification painting to pipelines should be no more than 10 meters indoors, as well as in outdoor installations, and no more than 60 meters on external main pipelines. Elements of identification painting must be applied at the passage of pipelines through walls and ceilings, in places where shut-off valves are installed, on inputs and outputs in buildings and installations. More details on the requirements for identification painting of pipelines can be found in GOST 14202.
It is also mandatory to apply warning rings that carry information about the degree of danger of the environment in the pipeline. The color and number of rings are given in tables 2-3, and the application diagram is in drawing 1.
Now about the number of rings:
| Table 3 - Number of warning rings depending on the pressure and temperature of the working medium in the pipeline | ||||
Number of warning rings | Transported substance | Pressure in kgf/cm2 | Temperature in °C |
|
| Superheated steam | Up to 22 | From 250 to 350 | ||

If it is necessary to apply yellow rings to gas (yellow) or acid (orange) pipes, their readability will be difficult. For this case, GOST 14202 provides for a black border with a width of at least 10 mm on the warning rings. A similar requirement applies in the case of applying green rings to a pipeline with water (also green) - white borders with a width of at least 10 mm are applied along the edges of the rings.
When carrying out construction, installation and other special work, a special place is occupied by the laying of main steel pipelines.

Pipelines are marked with the appropriate color, numbers, warning signs, and special shields, which allows even an inexperienced specialist to determine the contents and degree of risk of linear systems.
The color marking of pipelines corresponds to GOST 14202-69. According to this rule:
- green color corresponds to group 1, transports water;
- red color corresponds to group 2, transports steam;
- blue color corresponds to group 3, transports air;
- yellow color corresponds to 4-5 groups, transports flammable and non-flammable gases;
- orange color corresponds to group 6, transports acids;
- purple color corresponds to group 7, transports alkalis;
- brown color corresponds to groups 8-9, transports flammable and non-flammable liquids;
- gray color corresponds to group 0, transports other substances.
Important! Fire protection systems, regardless of the internal component, are always painted in the signal red color. If necessary, they additionally use other means of notation.

The stickers are also made in the form of arrows showing the direction of flow of the substance inside the pipe. The hands are also standardized in terms of size. The designation on the arrows is differentiated: “flammable substances”, “explosive and fire hazardous”, “toxic substances”, “corrosive substances”, “radioactive substances”, “attention - danger!”, “flammable - oxidizer”, “allergic substances” " The color of the arrows, as well as the inscriptions, is applied in black or white to achieve the greatest contrast with the main coating of the pipe.
For particularly dangerous components of communications, stickers are made in the form of warning signs (in addition to color rings). The signs are triangular in shape with a black image on a yellow background.
Important! In hot water supply systems and in the case of transporting leaded gasoline, the inscriptions must be white.
If the contents of the pipeline can damage the color designation or change its shade, special shields are used as additional markings, which are informative in numbers and letters. The requirements for shield graphics are identical to those for decals. The dimensional characteristics of the shields correspond to the characteristics of the arrows.

Colors and sizes of pipeline markings in accordance with GOST 14202-69
Unmarked pipes can be dangerous to life and property. Accidents, injuries and equipment damage can be caused by people not knowing what is in a particular pipe.
Correct pipe identification prevents fatal errors. Accidents caused by negligence in enterprises result in physical and psychological consequences for personnel and are often very costly for the enterprise.
Correct pipe identification ensures the best understanding of the building structure and ensures that new employees and temporary staff quickly gain a clear understanding. At the same time, this simplifies repair work and prevents time-consuming searches for the cause of the breakdown. In the event of an accident, proper identification will save valuable time - and may even help save someone's life.
We suggest you order and buy double-sided arrow stickers for pipelines in Moscow. Arrow markers are made of PVC film on an adhesive base, used in conditions from -40 to +80 degrees. The temperature during gluing of marking arrows should not be lower than +10 degrees. Stickers in the form of arrows are resistant to water and humidity; as well as exposure to slightly alkaline and slightly acidic environments.

Pipeline markings arrows, stickers.
All substances transported through pipelines are divided into 10 groups. Each group was assigned its own color. This did not affect only the groups “Flammable gases” and “Non-flammable gases”, and “Flammable liquids” and “Non-flammable liquids” - all gases are indicated in yellow, and liquids in brown.
Pipeline marking "Water"
The Water group is green. Pipeline markings arrows (or stickers) “WATER” indicate what kind of water is transported through the pipes:
cold water, hot water, city water, hot water supply, hot water return, cold water supply, cold water return, heating supply, heating return, distilled water, return water, chilled water, water for injection, clean water, process water, drinking water, contaminated water, condensate, condensate supply, condensate return, mineralized water, purified water, drainage, make-up water, direct heating, direct boiler circuit, source water, return boiler circuit, heating return, feed water, make-up water, direct hot water supply , chemically purified water, warm water, chilled water, sealing water, contaminated condensate, clean condensate, mixing water, decanter water, waste water, waste water, supply coolant, return coolant, fire extinguishing water
All these names of “Water” are depicted on a green background in white or black letters and have, respectively, a white or black edging around the perimeter of the marking arrow or sticker on the pipeline.
Pipeline marking "Steam"
The red background is used to indicate the following group of substances transported through pipelines: “STEAM”. Pipeline markings arrows (stickers) of the “STEAM” group are:

STATE STANDARD OF THE USSR PIPELINES OF INDUSTRIAL ENTERPRISES IDENTIFICATION PAINTING, WARNING SIGNS AND MARKING BOARDS
GOST 14202-69 USSR STATE COMMITTEE ON STANDARDS MOSCOW
STATE STANDARD OF THE USSR
Resolution of the Committee of Standards, Measures and Measuring Instruments under the Council of Ministers of the USSR dated February 7, 1969 No. 168 established the introduction date
1. This standard applies to identification paint, warning signs and marking panels of pipelines (including connecting parts, fittings, fittings and insulation) at designed, newly constructed, reconstructed and existing industrial enterprises inside buildings, on external installations and communications located on overpasses and in underground channels in order to quickly determine the contents of pipelines and facilitate the management of production processes, as well as ensure occupational safety.
The standard does not apply to identification painting of pipelines and ducts with electrical wiring.
2. The following ten enlarged groups of substances transported through pipelines are established:
3) air;
4) flammable gases (including liquefied gases);
5) non-flammable gases (including liquefied gases);
6) acids;
7) alkalis;
8) flammable liquids;
9) non-flammable liquids;
10) other substances.
3. Identification coloring and digital designation of enlarged groups of pipelines must correspond to those indicated in the table
1. 4. The characteristics of the colors of the identification paint must correspond to those specified in the application
1. 5. Fire pipelines, regardless of their contents (water, foam, steam for fire extinguishing, etc.), sprinkler and deluge systems in areas of shut-off and control valves and in places of connection of hoses and other fire extinguishing devices must be painted in red color (signal).
If it is necessary to indicate the contents of fire-fighting pipelines, additional marking is allowed by means of marking panels painted in the appropriate distinctive colors.
Table 1
| Transported substance | Samples and names of identification colors | |
| Digital group designation | Name | |
| 1 | Water | Green |
| 2 | Steam | Red |
| 3 | Air | Blue |
| 4 | Flammable gases | Yellow |
| 5 | Non-flammable gases | Yellow |
| 6 | Acids | Orange |
| 7 | Alkalis | Violet |
| 8 | Flammable liquids | Brown |
| 9 | Non-flammable liquids | Brown |
| 9 | Other substances | Grey |
6. Identification painting of pipelines should be carried out continuously over the entire surface of communications or in separate sections.
The method of performing identification painting should be selected depending on the location of pipelines, their length, diameter, the number of lines located together, safety requirements and industrial sanitation, lighting conditions and visibility of pipelines for operating personnel and the overall architectural design.
It is recommended to paint pipelines in sections in workshops with a large number and length of communications, as well as in cases where, due to working conditions, due to increased requirements for color rendering and the nature of the architectural design of the interior, a concentration of bright colors is undesirable.
Identification painting over the entire surface of pipelines is recommended for short lengths and a relatively small number of communications, if it does not worsen the working conditions in the workshops.
In outdoor installations, it is recommended to use identification paint over the entire surface only in cases where this does not cause deterioration in operating conditions due to the impact of solar radiation on communications.
7. When applying identification paint in sections to pipelines located inside industrial premises, it is recommended to paint the remaining surface of communications in the color of walls, partitions, ceilings and other interior elements against which the pipelines are located. In this case, it is not allowed to paint pipelines between sections with the identification color adopted to designate other enlarged groups of substances.
8. When applying identification paint in sections to pipelines located outside buildings, it is recommended to paint the remaining surface of communications in colors that help reduce the thermal impact of solar radiation on pipelines.
9. When laying communications in non-passable channels and when laying communications without channels, areas of identification painting on pipelines should be applied within the chambers and inspection wells.
10. Areas of identification painting should be applied taking into account local conditions at the most critical points of communications (at branches, at joints, flanges, at points of sampling and instrumentation, at places where pipelines pass through walls, partitions, ceilings, at inputs and outputs from industrial buildings etc.) at least every 10 m inside production premises and in outdoor installations and every 30-60 m on external main routes.
11. The width of the identification painting areas should be taken depending on the outer diameter of the pipelines (including insulation):
- for pipes with a diameter of up to 300 mm - at least four diameters;
- for pipes with a diameter of over 300 mm - at least two diameters.
If there are a larger number of parallel utilities, it is recommended that the areas of identification paint on all pipelines be of the same width and applied at the same intervals.
For large pipeline diameters, areas of identification painting may be applied in the form of stripes with a height of at least 1/4 of the pipeline circumference.
The width of the strips must correspond to the dimensions established for pipelines of a given diameter.
12. To indicate the most hazardous properties of transported substances, warning colored rings should be applied to pipelines.
The colors of the identification paint for the warning rings must correspond to those indicated in the table. 2.
13. In cases where a substance simultaneously has several dangerous properties, indicated by different colors, rings of several colors should be applied to pipelines at the same time.
On vacuum pipelines, in addition to the distinctive coloring, it is necessary to bear the inscription “vacuum”.
14. According to the degree of danger to human life and health or the operation of the enterprise, substances transported through pipelines should be divided into three groups, designated by the corresponding number of warning rings in accordance with Table 3.
15. The characteristics of signal colors must correspond to those specified in Appendix 2.
16. The width of the warning rings and the distance between them should be taken depending on the outer diameter of the pipelines in accordance with the drawing. 1 and table 4.
17. If there are a large number of parallel communications, warning rings on all pipelines should be of the same width and applied at the same intervals.
table 2
Notes:
1. When applying yellow rings to match the identification coloring of gas and acid pipelines, the rings must have black edges with a width of at least 10 mm.
2. When applying green rings to match the identification color of water pipelines, the rings must have white edges with a width of at least 10 mm.
18. Gas outlet lines and exhaust into the atmosphere, depending on their contents, must have an identification color established for the symbol of enlarged groups, with winding transverse rings of the corresponding signal color.
19. To designate pipelines with contents that are particularly dangerous to the health and life of people or the operation of an enterprise, as well as if it is necessary to specify the type of hazard, warning signs must be used in addition to colored warning rings.
20. Warning signs must indicate the following substances: toxic, flammable, explosive, radioactive, as well as other dangerous contents of pipelines (for example, substances that pose a splash hazard, etc.).
21. Warning signs must be in the shape of a triangle. Images must be black on a yellow background.
