ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. Among them, cold drawn has higher dimensional accuracy than hot rolled, and the surface of hot rolled steel pipe is relatively rough. The large-diameter seamless steel pipe is hot-rolled steel pipe, and the small-diameter is cold drawn.

ASTM A192,ASME SA192 High-Pressure Seamless Boiler And Superheater Tubes are made by the seamless process and shall be either hot-finished or cold-finished, as specified.

ASTM A572 GR.42 welded pipe has high strength and good toughness. It is widely used in various structural projects that require welded steel pipes.

ASTM A179 and ASTM A192 are specifications for carbon steel pipes used in different applications.
