ASTM A53 Standard Steel Pipe is the America Standard.it devided into A53-F A53-A, A53-B. The production processes of ASTM A53 Standard Steel Pipe: billet → heating → perforation→ Three roller rolling→detached → sizing → cooling → straightening → hydrostatic test → mark → storage. Cold Drawn Production processes: billet → heating → perforation→ annealing → pickling → oiled → pass cold drawing → blank pipe → heat treatment → straightening → hydrostatic test → mark → storage. The surface roughness of cold drawn steel pipe and average of wall thickness is better than hot rolled steel pipe
