A106B Seamless Steel Pipe buy direct from china manufacturer is hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines.Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time.

Carbon steel seamless pipe

 

Seamless steel tube products for machining use tube blanks (mainly continuous casting blanks) as raw materials, which are heated
and rolled into steel tubes by centering, piercing, continuous rolling and tension reduction units. At the same time, the
supporting production equipment such as tube end thickening, pipe joint processing, tool joint processing, heat treatment,
ultrasonic, magnetic flux leakage, eddy current, magnetic particle on-line flaw detector, spectrum and hardness tester can meet the various requirements of different users.

 

The shiny surface below is our precision seamless tube. The precision seamless tube has the characteristics of bright surface and precise size.
