6. The identical coloring of pipelines should be performed solid over the entire surface of the communications or individual sections.

The method of performing identification color should be selected depending on the location of pipelines, their length, diameter, the number of disposable joints, safety requirements and industrial sanitation, the conditions of illumination and visibility of pipelines for service personnel and the overall architectural solution.

The painting of pipelines is recommended to perform in workshops with a large number and high length of communications, as well as in cases where, under the conditions of work, due to increased requirements for the color rendering and the nature of the architectural solution of the interior, the concentration of bright colors is undesirable.

The identifiable color over the entire surface of the pipelines is recommended to be used with a small length and relatively small number of communications, if it does not impair the conditions of work in the workshops.

On external installations, the identification color over the entire surface is recommended only in cases where it does not cause deterioration of operating conditions due to the impact on the communications of solar radiation.

7. When applying an identification color by areas on pipelines inside the industrial premises, the rest of the communication surface is recommended to be painted in the color of walls, partitions, ceilings, and other interior elements, against which pipelines are located. It is not allowed to paint pipelines between the sections of the identification color, adopted to designate other enlarged groups of substances.

8. When applying an identification color to the areas on pipelines outside the buildings, the remaining surface of the communications is recommended to be painted in colors that contribute to a decrease in the thermal effects of solar radiation into pipelines.

9. When laying communications in non-voluntary channels and with a non-cash gasket of communications, the sections of the identification color on the pipelines should be applied within chambers and viewing wells.

10. Plots of the identification color should be applied with local conditions in the most responsible points of communication (on branches, in places of compounds, flanges, at selection and kip sites, in places of pipeline pipelines through walls, partitions, overlaps, on inputs and conclusions from industrial buildings etc.) at no less often than 10 m inside the industrial premises and on external installations and after 30-60 m on external mainstream tracks.

11. The width of the sections of the identification color should be made depending on the outer diameter of the pipelines (taking into account the 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 more parallel communications, the sections of the identification color on all pipelines are recommended to take the same width and apply them with the same intervals.

For large diameters of pipelines, the sections of the identification color is allowed to be applied in the form of a strip, a height of at least 1/4 of the circle of the pipeline.

The width of the bands must correspond to the sizes installed for pipelines of this diameter.

12. To denote the most dangerous properties of transportable substances to pipelines, warning colored rings should be applied.

The colors of the identification color for the warning rings must match the specified in Table. 2.

13. In cases where the substance simultaneously has several hazardous properties denoted by various colors, several colors rings should be applied to the pipelines at the same time.

On vacuum pipelines, except distinctive color, it is necessary to give the inscription "Vacuum".

15. Characteristics of signal colors must comply with the application 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 features. 1 and table. four.

17. With a large number of parallel communications, warning rings on all pipelines should be made the same width and apply them with the same intervals.

table 2

Notes:

1. When applying a yellow rings according to the identification color of the pipelines of gases and the acid acids should have black garages width of at least 10 mm.

2. When applying green rings according to the identification color of the water pipelines, the ring must have white cuts width of at least 10 mm.

21. Warning signs must have a triangle shape. Images should be black on a yellow background.

23. In cases where the shade of distinctive colors can occur from the effects of aggressive occurring substances, the pipelines must be designated using marking panels.

24. Marking shields should be used for additional designation of the type of substances and their parameters (temperature, pressure, etc.) required by operating conditions. On marking pads on pipelines or on the surface of the structures, which attached pipelines should be applied alphabetic or digital inscriptions.

An designation of the type of substance is allowed through numbers in accordance with Appendix 3. The designation of the type of matter through chemical formulas is not allowed.

26. The direction of flow of substances transported by pipelines should be specified with the sharp end of marking plates or arrows, applied directly to pipelines.

The shape and size of the arrows must fit the form and size of marking flaps.

27. Marking shields must be performed by 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 specify the place of selection of the transported substance.

The color of the marking inscriptions and the shooters indicating the direction of flow applied to pipelines and marking shields should be white or black, taking into account the provision of the greatest contrast from the main painting pipelines.

The color of the inscriptions when applied to them on the background of the identification painting takes:

white - on green, red and brown background;

black - on blue, yellow, orange, violet and gray background.

32. The size of marking flaps, inscriptions and warning signs must be selected depending on the distance from which they should be perceived by the personnel associated with the operation of pipelines in accordance with the features. 5 and table. eight.

The color of fireproof pipelines and equipment is recommended to perform red enamel on technical documentation approved in the prescribed manner.

37. The colors of the identification color and signal colors are allowed to be taken in accordance with the following references of the color standards of the color standards: Green No. 343-344; Red No. 10-11; Blue No. 423-424; Yellow No. 205-206; Orange No. 101-102; purple No. 505-506; Brown No. 647-648; Gray No. 894-895.

The color of fireproof pipelines and equipment is recommended to perform red enamel on technical documentation approved in the prescribed manner.

37. The colors of the identification color and signal colors are allowed to be taken in accordance with the following references of the color standards: Green N 343-344; Red N 10-11; Blue N 423-424; Yellow N 205-206; Orange N 101-102; purple n 505-506; Brown N 647-648; Gray N 894-895. The necessary shades of purple and brown colors in accordance with the samples of Table 1 can be obtained by adding white paint.

Marking shields, warning signs and inscriptions on pipelines should be placed in well-lit places or highlights to ensure their clear visibility, while light sources should not close images and inscriptions, as well as dazzling staff when observing them.

The smallest illumination at the responsible points of communication at the location of the marking flaps, inscriptions and warning signs is recommended to take 150 LCs with fluorescent lamps and 50 LCs under incandescent lamps.
