1. This standard applies to the identification coloring, warning signs and marking plates of pipelines (including fittings, fittings, fittings and insulation) at designed, newly built, reconstructed and existing industrial enterprises inside buildings, at outdoor 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 ensuring labor safety.

The standard does not apply to the identification coloring of pipelines and ducts with electrical wiring.

2. The following ten enlarged groups of substances transported through pipelines are established:

1) water;

3) air;

4) combustible gases (including liquefied gases);

5) non-flammable gases (including liquefied gases);

6) acids;

7) alkalis;

8) combustible liquids;

9) non-flammable liquids;

0) other substances.

3. Identification coloring and digital designation of enlarged groups of pipelines must correspond to those indicated in Table 1.

Table 1

4. Characteristics of colors of identification coloring should correspond to those specified in Appendix 1.

5. Fire-fighting pipelines, regardless of their contents (water, foam, steam for extinguishing a fire, etc.), sprinkler and deluge systems in the areas of shut-off and control valves and at the points of connection of hoses and other fire extinguishing devices must be painted red (signal).

If it is necessary to indicate the contents of fire-fighting pipelines, it is allowed to additionally designate them by means of marking plates painted in the appropriate distinctive colors.

6. Identification painting of pipelines should be carried out continuously over the entire surface of communications or in separate sections.

The method for performing identification painting should be selected depending on the location of the pipelines, their length, diameter, the number of lines located together, safety and industrial sanitation requirements, lighting conditions and visibility of pipelines for maintenance personnel and the general architectural solution.

It is recommended to paint pipelines in sections in workshops with a large number and great length communications, as well as in cases where, due to the increased requirements for color reproduction and the nature of the architectural solution of the interior, the concentration of bright colors is undesirable.

Identification painting over the entire surface of pipelines is recommended for use with a small length and a relatively small number of communications, if it does not worsen working conditions in the shops.

On outdoor installations, it is recommended to use identification coloring over the entire surface only in cases where this does not cause deterioration of operating conditions due to the effect of solar radiation on communications.

7. When applying identification coloring in sections to pipelines located inside industrial premises, it is recommended to paint the rest of the communications surface in the color of walls, partitions, ceilings and other interior elements against which the pipelines are located. At the same time, it is not allowed to paint pipelines between sections with an identification color adopted to designate other enlarged groups of substances.

8. When applying identification coloring in sections to pipelines located outside buildings, it is recommended to paint the rest of the communications surface in colors that help reduce the thermal effect of solar radiation on pipelines.

9. When laying communications in impassable channels and when laying communications without channels, areas of identification coloring on pipelines should be applied within the chambers and manholes.

10. Areas of identification coloring should be applied taking into account local conditions at the most critical communication points (at branches, at joints, flanges, at sampling and instrumentation points, at places where pipelines pass through walls, partitions, ceilings, at inputs and outputs from industrial buildings etc.) at least every 10 m inside production facilities and outdoor installations and every 30-60 m on external main routes.

11. The width of the areas of identification coloring 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 more than 300 mm - at least two diameters.

With a larger number of parallel communications, it is recommended that the areas of identification coloration on all pipelines be of the same width and applied at the same intervals.

With large diameters of pipelines, areas of identification coloring may be applied in the form of strips 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 designate the most hazardous substances transported by properties, warning color rings should be applied to pipelines.

Identification colors for warning rings must correspond to those indicated in Table 2.

table 2

Notes:

1. When applying rings yellow color according to the identification coloring of pipelines of gases and acids, the rings must have black borders with a width of at least 10 mm.

2. When applying green rings for the identification color of water pipelines, the rings must have white borders with a width of at least 10 mm.

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 color, it is necessary to give 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, indicated by the corresponding number of warning rings in accordance with Table 3.

Table 3

Note. For substances that are dangerous in terms of properties or a combination of properties that are not included in this table, hazard groups should be established in agreement with the bodies of Gosgortekhnadzor.

15. Characteristics of signal colors must comply with those specified in Appendix 2.

16. The width of the warning rings and the distance between them must be taken depending on the outer diameter of the pipelines in accordance with Figure 1 and Table 4.

17. With a large number of parallel communications, warning rings on all pipelines should be of the same width and applied at the same intervals.

18. Gas outlet lines and venting to the atmosphere, depending on their contents, must have an identification color established for the symbolic designation of enlarged groups, with winding transverse rings of the corresponding signal color.

19. To designate pipelines with content that is especially hazardous to human health and life or the operation of an enterprise, as well as, if necessary, to specify the type of hazard, warning signs should be used in addition to color warning rings.

20. Warning signs should indicate the following substances: poisonous, flammable, explosive, radioactive, as well as other dangerous contents of pipelines (for example, substances that are hazardous when splashed, etc.).

21. Warning signs should be in the form of a triangle. Images must be black on a yellow background.

22. The image of warning signs should be taken in accordance with Figure 2 and Table 5.

23. In cases where the impact of aggressive flowing substances can cause a change in the hue of distinctive colors, pipelines should be marked with marking plates.

24. Labeling plates should be used to additionally indicate the type of substances and their parameters (temperature, pressure, etc.) required by the operating conditions. Marking plates on pipelines or on the surfaces of structures to which pipelines are attached must be marked with alphabetic or numeric inscriptions.

25. The inscriptions on the shields of the pipelines must be made in a clear, well-defined font and must not contain unnecessary data, little-used terms and incomprehensible abbreviations. The font for inscriptions is recommended to be taken in accordance with GOST 10807-78*.
________________
* On the territory of the Russian Federation, GOST R 52290-2004 applies. - Database manufacturer's note.

It is allowed to designate the type of substance by means of numbers in accordance with Appendix 3.

The designation of the type of substance by means of chemical formulas is not allowed.

26. The direction of the flow of substances transported through pipelines must be indicated by the sharp end of the marking plates or arrows applied directly to the pipelines.

The shape and size of the arrows must match the shape and size of the labels.

27. Marking shields must be of four types:

1 - to indicate the flow moving in both directions;

2 - the same, in the left direction;

3 - the same, in the right direction;

4 - to indicate the place of selection of the transported substance.

28. The dimensions of the marking plates must correspond to those indicated in Fig. 3 and in Table 6.

Damn.3. - Dimensions of labels

Table 6

29. Size options for labels, inscriptions and warning signs should be used mainly:

1 - in laboratories;

2 and 3 - in industrial premises;

4 and 5 - on outdoor installations and outdoor main routes.

30. When attaching them to pipelines, warning signs should be placed together with marking plates.

31. The height of markings on pipelines should be taken depending on the outer diameter of the pipeline in accordance with Figure 4 and Table 7.

Damn.4. - Height of markings on pipelines

Table 7

The color of markings and arrows indicating the direction of flow applied to pipelines and marking plates should be white or black, taking into account the greatest contrast with the main color of the pipelines.

The color of the inscriptions when applied against the background of identification coloring is taken:

white - on a green, red and brown background;

black - on a blue, yellow, orange, purple and gray background.

32. The size of labels, inscriptions and warning signs should be selected depending on the distance from which they should be perceived by personnel associated with the operation of pipelines in accordance with Figure 5 and Table 8.

33. Paint and varnish coatings for identification painting, marking plates and warning signs must be carried out in accordance with the current standards for paintwork materials and coatings, depending on the material of pipelines or the insulation protecting them and operating conditions, as well as the cost of paint and varnish coatings and the technology of their application.

34. Paints and varnishes used for identification painting, marking plates and warning signs must meet the requirements of the relevant standards, as well as technical documentation approved in the prescribed manner.

35. When preparing surfaces for painting, applying and drying paint and varnish coatings, the safety regulations and fire prevention measures provided for by the current fire regulations and rules must be observed.

36. In heated and ventilated industrial premises without aggressive environments, it is recommended to carry out the identification coloring of pipelines, marking plates and warning signs with pentaphthalic enamels of grades PF-115 according to GOST 6465-76, PF-133 according to GOST 926-82 and other brands according to the technical documentation approved according to established order.

It is recommended to paint fire-fighting pipelines and equipment with red enamel according to the technical documentation approved in the prescribed manner.

37. Identification colors and signal colors are allowed to be accepted in accordance with the following standards of the color standard card index: green N 343-344; red N 10-11; blue N 423-424; yellow N 205-206; orange N 101-102; violet N 505-506; brown N 647-648; gray N 894-895. The required shades of purple and brown in accordance with the samples of Table 1 can be obtained by adding white paint.

38. The identification coloring of pipelines and the color finish of marking plates and warning signs should be periodically renewed, taking into account the provision of clear visibility of colors, images and inscriptions. The coloring should be even, without streaks, wrinkles, spots and should not peel off.

39. Marking boards, inscriptions and warning signs should be located taking into account local conditions at the most critical communication points (at branches, at junctions, at points of selection, at valves, gate valves, valves, gates, control devices, at places where pipelines pass through walls , partitions, ceilings, at inputs and outputs from industrial buildings, etc.).

Marking plates, warning signs and inscriptions on pipelines should be located in well-lit places or illuminated to ensure their clear visibility, while light sources should not obscure the images and inscriptions, as well as dazzle personnel when observing them.

It is recommended to take the lowest illumination at critical communication points with marking plates, inscriptions and warning signs in them at 150 lux with fluorescent lamps and 50 lux with incandescent lamps.

40. In all industrial premises where there are pipelines, in places that are well accessible for viewing, identification coloring schemes for communications should be hung out with a decoding of the distinctive colors, warning signs and digital designations adopted for marking pipelines.
