1) water;

3) air;

4) Gases combustible (including liquefied gases);

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

6) acid;

7) alkali;

8) flammable liquids;

9) non-combustible fluids;

0) Other substances.

3. The identification color and digital designation of the enlarged groups of pipelines must match the specified in Table 1.

5. Fireparts, regardless of their contents (water, foam, steam to extinguish fire, etc.), sprinkler and dramet systems in areas of shut-off-regulating reinforcement and in places of connection of hoses, etc. Devices for extinguishing fires should be painted red (signal).

If it is necessary to indicate the content of fire pipelines, an additional designation is allowed by the marking panels painted into the corresponding distinctive colors.

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.

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 of 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 correspond to the specified in Table 2.
