Stainless steel EP pipe, also known as electrolytic polished stainless steel pipe, is a high-purity stainless steel pipeline that has undergone special electrochemical polishing treatment.
It, together with another type of BA tube (bright annealed tube), constitutes the two major pipeline types in high-purity applications.
The core of EP tube lies in its internal surface treatment technology. By immersing stainless steel pipes in a charged electrolyte solution and utilizing the principle of anodic dissolution, micro defects and fouling layers on the surface of the pipes are gradually eliminated.
This process can reduce the roughness of the inner surface of the pipeline to Ra ≤ 0.3 microns or less, forming a mirror like smooth surface.
Compared to traditional stainless steel pipes, EP pipes have a smoother surface, better corrosion resistance, and extremely strong ion precipitation control ability
