SSAW steel pipes and cs seamless pipes have different definitions, characteristics, processing techniques and uses. We need to choose according to the actual situation.

The deviation and ovality specification range between stainless steel seamless steel pipes with different wall thicknesses are also different.Stainless seamless steel pipe standards stipulate the allowable index of ovality, which is generally specified as not exceeding 80% of the outer diameter tolerance.

The performance of seamless black steel pipes is affected by many aspects, and its excellent performance contributes to better use.

The quenching and tempering of seamless pipe is a very important and widely used process in the heat treatment process. Quenching can significantly increase the strength and hardness of steel.

For cold drawn seamless tubing, how to calculate how much pressure it can withstand when the outer diameter and wall thickness are known?

Tensile test is one of the important means to test the mechanical properties and material properties of cold drawn seamless tubing.
