Round Steel Pipe Exporter

A steel material having a hollow concentric circular section at both ends and having a relatively large length and a periphery. The specifications of steel pipes are expressed in terms of external dimensions (such as outer diameter or side length) and inner diameter and wall thickness. They range in size from small diameter capillaries to large round pipes up to several meters in diameter.
Round steel tubes can be used in pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special applications.we are round steel pipe exporter.
classification
According to the production method, it can be divided into seamless round steel pipe and welded round steel pipe.
Seamless steel pipe manufacturing process
Tube blank--inspection--peeling--inspection--heating--perforation--pickling--repairing--lubricating air-drying--welding head--cold drawing--solution treatment--sickling--sour washing Passivation--test
Welded steel pipe manufacturing process
Strip--Inspection--Shear--Fixed--Qualitative--Welding--Flating (Seamless)--Fixed--Test
