galvanized steel pipes and galvanized seamless steel pipes are different in terms of production process, performance characteristics, scope of use, price, etc. When we choose to use them, we need to choose the most suitable material according to our own needs.

ERW pipes are produced from hot-rolled or cold-rolled flat coils.Drawn Over Mandrel (DOM) tubes are produced from fully annealed ERW pipes through a cold drawing process.

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.
