Posted by:Rain Time:2019.08.08 01:51

The seamless steel tube has a hollow section, which is used as a conduit for conveying fluids, such as tubes for oil, gas, gas, water and 

some solid materials. Compared to the steel tube and the torsion resistance phase in solid steel round steel at the same time, the weight 

is lighter, it is a kind of economical cross-section steel, widely used in the manufacture of structural and mechanical parts, such as tubes 

of oil drilling, automatic transmission shaft, bicycle frame and construction of steel scaffolding are used with annular parts for the production 

of steel pipes, such as improving the use of the material, simplifying the manufacturing process, saving material and time processing, such 

as rolling ring, set of jacks, etc. It has been widely used to make steel tubes.


1. Seamless steel pipe is widely used. The common use of seamless steel pipe is made of ordinary carbon structural steel, structural lamination 

in alloy steel or light alloy, with the highest efficiency, mainly used as a conduit or structural parts for conveying fluids. .


2. Supply according to different USES: a, based on the chemical composition and mechanical performance. B. Supply for mechanical performance. 

C. Provide with water pressure test. The steel pipes supplied by class a and class b must also be tested for hydraulic pressure.


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

for oil.
