Notes:

  1. The nominal pressures given in the “steam and hot water” column apply only to pipeline components covered by the “Rules for the Design and Safe Operation of Steam and Hot Water Pipelines” of the USSR Gosgortekhnadzor.

  2. Pipe caps whose nominal pressure is marked with an asterisk (*) are intended for the special operating conditions specified in clause 1.1g of GOST 17380-83.

  3. Pipe caps whose wall thickness is marked with a double asterisk (**) are manufactured only from steel 09G2S.

  4. Mass is given for reference.

(Amendment No. 2).

Example of a designation for a pipe cap with Dn = 530 mm, s = 10 mm, made of steel 20:
