1/8"-4" ASTM A182 F22 MSS SP95 concentric eccentric swaged nipples

A182 F22 Forged Pipe Fitting

ASTM A182 F22

Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service

Scope
This specification covers forged low-alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves and similar parts to specified dimensions or to dimensional standards. Products made to this specification are limited to a maximum weight of 10,000 lb.

Process
The low-alloy ferritic steels shall be made by the open-hearth, electric-furnace or basic-oxygen process with the option of separate degassing and refining processes in each case. The stainless steels shall be melted by one of the following processes: Electric-furnace (with the option of separate degassing and refining processes), vacuum-furnace or one of the former followed by vacuum or electroslag-consumable remelting.

Heat treatment
After hot working, forgings shall be cooled to a tem­perature below 1000 °F (538 °C) prior to heat treating in accordance with the requirements of ASTM A182. The low-alloy steels and ferritic and martensitic stainless steels shall be heat treated in accordance with the requirements of ASTM A182.
