Boiler Seamless Carbon Steel Pipe ASTM A106 Gr. C For High Temperature Operation
A106 is only produced as a seamless product and is available in three grades; A, B, C. There are no Types in A106 because it is produced only as a seamless product.
The ASTM A106 specification is for seamless carbon steel pipe for High-Temperature Service. It covers nominal pipe sizes (NPS) 1/8” NPS to 48 NPS”. For sizes 1- 1/2” NPS and under, A106 may be produced by two different processes; either hot finished or cold drawn. Unless otherwise specified, pipe 2″ NPS and over shall be furnished hot finished. Typical uses for A106 are for handling liquids and gasses at high temperatures and pressures in power plants, oil refineries, and industrial facilities.
