Stainless Steel EP Tube is derived from BA pipe through electrochemical polishing. We deploy the stainless steel into special chemical solution consisting of all kinds of elements, and utilize anodic dissolution under electropolishing condition to achieve smooth and bright surface. As a result, the inner surface roughness is increased to 0.20μm.
