What Is Seamless Steel Tube?

- May 04, 2018-

The seamless steel tube has a hollow section, which is used as a pipeline for conveying fluids, such as pipes for oil, gas, gas, water and certain solid materials. 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, such as rolling bearing ring, jack sets, etc., has been widely used to make steel pipe.

1. Seamless steel pipe is widely used. The common use of seamless steel tube consists of ordinary carbon structural steel, low-alloy structural steel or alloy structural steel rolling, with the most output, mainly used as pipeline or structural parts for conveying fluids. .

2. Supply according to different USES: a, according to chemical composition and mechanical performance; B. Supply by mechanical performance; C. Supply by water pressure test. Steel tubes supplied by class a and class b shall also be tested for hydraulic pressure.

3. The special purpose of seamless pipe is seamless tube for boiler, seamless steel tube for geological use and seamless pipe for petroleum.
