Electrochemical polishing, also known as electropolishingor electrochemical polishing, is a method that utilizes theelectrochemical dissolution phenomenon generated by the anode in an electrolytic cell to selectively dissolve the micro protrusionson the anode, forming a smooth surface. During electrolyticpolishing, the sample is used as the anode, and insoluble metals areselected as the cathode. By electro polishing, the sharp edges andsmooth depressions on the metal surface can be removed, whichcan improve the surface morphology and structure, form a closedchromium oxide film, and enhance the corrosion resistance of thepipeline. Generally, mechanical polishing (which requires grindingand polishing) is performed before electric polishing to makethe surface of the product smoother and eliminate dead corners.

Senmai Clean Stainless Steel EP Pipe uses our company's BA asthe main pipe and then undergoes electrolytic chemical polishingto achieve industry standards for surface roughness, surfacedefects, Cr/Fe ratio, oxide layer thickness, etc. It has excellentcorrosion resistance and can maintain good performance even inharsh environments such as high temperature and high pressure.Due to its excellent performance, Senmai clean stainless steel EPpipes are widely used in pipeline transportation systems in industriessuch as semiconductors, optoelectronics, bio BPE, specialty gases,and new energy.
