Product Description

Stainless Steel Square Tube:

Square tube is a kind of rectangular tube, contained in the rectangular tube. A large number of pipelines used to transport fluids, such as oil, natural gas, water, gas, steam, etc., in addition, in the bending, torsional strength at the same time, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Product Advantage

Stainless steel square pipe quality superior, health, environmental protection, economic and practical. The thin-walled pipeline and the new reliable, simple and convenient connection method have been successfully developed. Heat treatment: bright solid solution under the protection of reducing gas, mechanical properties analysis: the elongation Ψ strength δb, and hardness HRB(80~90) can be adjusted and controlled.

Product Apply

The use of square pipe: there are construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agriculture and chemical machinery, glass curtain wall, automobile chassis, airport, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, Bridges, power station equipment.
