BA Stainless Steel Tube is a part of stainless steel annealing process which is conducted in atmosphere of hydrogen protection or vacuum. The thermal process technology delivers resistance to oxidation and certain brightness to surface. Therefore, inner surface roughness is less than 0.4μm, and outer surface is less than 0.6μm.This product is the time-verified pipe fitting for ultra-pure and special gas piping system. It also finds extensive applications in industries of photoelectricity, semi-conductor, solar chemical, medicine and food, etc. Furthermore, BA pipe is the base material for EP pipe.
