Large diameter welded pipe

Description: Seamless steel pipe, also known as hot-rolled seamless steel pipe or hot-rolled steel pipe, is widely used in combustible and non combustible fluid transportation pipelines, boilers, and steel structures.

Seamless steel pipes shall comply with APISPEC5L, APISPEC5CT, and EN10217 standards.

Seamless steel pipe materials: 10 #, 20 #, 35 #, 45 #, 20G, 40Cr, 20Gr, 16Mn-45Mn, 27SiMn, Cr5Mo, 12CrMo (T12), 12Cr1MoV, 10CrMo910, T91, 15CrMo, 35CrMo, 40CrMo, etc. Description: Large diameter welded pipes generally use double-sided submerged arc welding technology, and can be divided into large-diameter straight seam welded pipes and large-diameter spiral welded pipes according to their different welding seams. Among them, straight seam steel pipes can be divided into UOE, RBE, etc. according to the different forming methods JCOE steel pipes, etc.

TAG: Seamless steel pipes, structural steel pipes, large-diameter straight seam welded pipes.
