Stainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. The thicker the wall thickness of the stainless steel seamless pipe, the more economical and practical it is, and the thinner the wall thickness, the higher its processing cost will be.

Resistance welding is a method of combining the workpieces and applying pressure through the electrodes, using the resistance heat generated by the current passing through the contact surface of the joint and the adjacent area for welding.

The steel pipes should be prevented from being damaged during bundling and transportation, and the bundling signs should be uniform.

In order to prevent sinking, indentation, scratches and thread damage of the pipe body, it should be hoisted by disk crane, nylon belt or steel wire rope with protective spacer when loading.

Seamless steel pipes have good mechanical properties and are widely used in oil, natural gas, electric power, boilers, transportation of oil and natural gas, water, steam, gas, liquefied petroleum gas, etc. However, in some environments, the internal temperature of the seamless steel pipe is high, the moisture is large, the corrosion environment is harsh, and it is easy to rust, which is easy to cause property loss.

Mechanical properties are an important indicator to ensure the end-use performance of seamless steel pipes, which depend on the chemical composition and heat treatment system of the steel.
