Process

Seamless stainless steel pipe is made from solid stainless steel bar which is called billet. By using different processing techniques such as extruding, gun drilling or piercing, the steel bars are produced to be steel tubes.

1. Firstly, the billets would be inspected exactly.
2. Then put the billets into the heat to raise the temperature.
3. The hot billets would then be pierced through the center with a mandrel. Through this procedure, the bar shape billet becomes hollow shape billet.  
4. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets all the specifications with length, diameter and wall thickness according to requirements.
