SUS 304 316L stainless steel seamless square pipe

Seamless square rectangular pipe is a kind of hollow section with no joints around the strip of steel. The pipe is hollow, has a certain cross-sectional area, a lot of used for conveying fluid pipeline, such as conveying oil, natural gas, gas, water and some solid materials pipeline, ring section under internal or external radial pressure, the force is more uniform, therefore, the vast majority of steel pipe is round pipe. However, the round pipe also has certain limitations, such as under the condition of plane bending, the round pipe is not as strong as the square, rectangular pipe bending strength, some agricultural machinery skeleton, steel and wood furniture, etc., commonly used square, rectangular pipe. Stainless steel square tube is a hollow strip of steel, because the cross section is square so called square tube. A large number of used for conveying fluid pipelines, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength at th…
