Sanitary Valve is a kind of stainless steel pipe fittings. It is called stainless steel mirror pipe because its surface roughness level is very high. The surface quality level can reach "8K", which is as bright as a mirror, so it is called stainless steel mirror pipe.

The material of stainless steel mirror pipe is also stainless steel. It is also the 8K surface quality achieved by stainless steel pipe fittings after multiple polishing processes, which is called mirror pipe. Stainless steel pipes are mainly made of austenitic stainless steel. The common ones are 0Cr18Ni9, 1Cr18Ni9Ti, etc. Stainless steel mirror pipes are made of these stainless steel pipes after processing and polishing. The processing technology is generally bright annealing. Mirror stainless steel pipes are divided into seamless stainless steel bright annealing pipes and welded bright annealing pipes. Seamless ones are generally used in medical, aviation, sensors, nuclear power instruments, etc. Welded ones are generally used for decoration. Stainless steel mirror pipes are mostly used in the oil pipelines of power plants, such as the EH oil pipelines of steam turbines.
