Stainless Steel - Ultra-pure BA/EP Tubes

In addition to stainless steel clean pipes, leveraging Class 10 cleanrooms, we also produce ultra-clean pipes - these pipes are manufactured using vacuum double-melting technology, with even higher cleanliness.Stainless steel ultra-pure clean tubes in the semiconductor industry typically require special refining methods to ensure material purity and consistency, thereby meeting strict cleanliness requirements. These tubes are commonly used in gas and liquid delivery systems in semiconductor manufacturing equipment to ensure the purity of media throughout the manufacturing process remains uncontaminated. Below are some of the special refining methods used to manufacture such ultra-pure stainless steel tubes:

1.Vacuum Induction Melting (VIM): This process significantly reduces the gas content in metals (such as oxygen, nitrogen, and hydrogen) and can also remove some non-metallic inclusions.

2.Vacuum Arc Remelting (VAR): This process further improves the purity of the metal, reduces inclusions, and helps achieve more uniform composition.
3.Electroslag Remelting (ESR): effectively removes non-metallic inclusions from the metal, improving the material's purity. Product Features：

• Very low ABCD inclusion content.
• Very low N.H.O element content.
