1 Scope

This standard applies to welded steel vessels and equipment (hereinafter – the vessels), operating at a pressure of more than 16 MPa (160 kgf / cm ² ), a vacuum with a residual pressure of at least 665 Pa (5 mm Hg. tbsp.) or without pressure ( for filling) and the wall temperature is not lower than minus 70 ° C, for use in chemical processing plants, petrochemical, refinery, oil, gas and other related industries.

This standard specifies the basic technical requirements for the design, materials, manufacturing (doizgotovleniyu), test methods, acceptance and delivery, reconstruction, repair, installation vessels and vehicles.

This standard does not apply to:

- Vessels operating under vacuum with a residual pressure of less than 665 Pa (5 mm Hg. Tbsp.)

- Containers intended for transportation of petroleum and chemical products;

- Cylinders for compressed, liquefied and dissolved gases;

- Tubular furnace;

- Tanks (containers) for storage of chemicals and petroleum products, projected in accordance with building codes and special rules.

In addition to the requirements of this standard should be guided by the rules and regulations on industrial safety.
