Manufacturing Process:
Steelmaking process:
The steelmaking process is at the discretion of the manufacturer. The steel shall be fully killed. 6.2 Tube manufacturing process:
The tubes shall be manufactured by a seamless (S) or longitudinally welded (W) process, as specified (see 5.1 b). Cold formed tubes of Type L shall be heat treated (see B.2). The other series and types of tubes may be heat treated at the discretion of the manufacturer Tubes shall not include welds used to join lengths of strip prior to forming the tube.
