ERW welded pipe forming technologies include roll forming and row roller forming method

Drawn Over Mandrel Tubing (DOM) is made from fully annealed ERW pipe through a cold drawing process.Seamless steel pipes are manufactured using a method called extrusion.

The stainless steel ERW pipe production process refers to processing steel plates into pipes through resistance heating. This kind of pipeline has the characteristics of beautiful appearance and long service life, and is widely used in construction, chemical industry and other fields.

ERW Pipe Forming Technology includes flexibility of molding system,super row roller,quick roll changing technology and computer control of molding system.

The production process of straight seam steel pipe is divided into high frequency welding process and submerged arc welding process.Seamless steel pipes are a production process in which round steel is perforated and formed in one go.

ERW pipeline assessment includes non-destructive and destructive testing.
