If the deformation of EN 10297-1 C45 seamless steel pipe is small during the air drawing process, the inner and outer surface layers will generate additional stress due to external pressure and internal tension.

EN10217-2 P265GH steel pipe connection mode, metal welding, according to the characteristics of its process is divided into fusion welding, pressure welding and brazing three categories. The fusion welding of EN10217-2 P265GH steel pipe is a method of hea

It has a thick and dense pure zinc coating on the surface of DIN 17175 14mov63 seamless steel pipe, which can avoid the contact between the base of DIN 17175 14MoV63 seamless steel pipe and any corrosion solution, and protect the steel base from corrosion

Features of hot-dip galvanized DIN 2445-1 ST52.4 seamless steel pipe: the surface of hot-dip galvanized DIN 2445-1 ST52.4 seamless steel pipe is bright and beautiful. Pure zinc layer is the most plastic layer in hot dip galvanizing, its properties are bas
