The raw material of black steel seamless pipe is iron, which will rust after a long time, affecting the service life in the pipeline and causing unnecessary losses. Therefore, the anti-corrosion of black steel seamless pipe is a process that must be done before pipeline construction.

The stainless steel welding methods used in industry mainly include tungsten argon arc welding (TIG), high frequency welding, plasma welding and laser welding.

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.
