Description. Specification. ASTM A53 Gr.B electric resistance welded (ERW) steel pipes are manufactured as per ASTM A53 specification,they are welded steel pipes made by electric resistance welding method. ASTM A53 specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 18 to NPS 26 (DN6 to DN 650).It is acceptable for welding,flagging,and bending. Can PSL 2 pipes be welded?Can PSL 2 pipes be welded?Both conductors are placed in close proximity with most of the HF current flowing on the adjacent sides of the conductors. According the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process the HFW welding is a mandatory requirements for ERW steel pipes.Differences between ERW Steel Pipe and HFW Steel Pipe How are welded pipes made?How are welded pipes made?Welded Pipes are manufactured from Plate or continues Coil or strips. To manufacture welded pipe, first plate or coil is rolled in the circular section with the help of plate bending machine or by a roller in the case of continues process. Once the circular section is rolled from the plate, the pipe can be welded with or without filler material.What is a Welded Steel Pipe?
