Is there any difference between stainless steel precision pipe and ordinary pipe?
There is. 1, pipe diameter size tolerance is different: stainless steel precision pipe and ordinary pipe the most fundamental difference lies in its precision. Ordinary stainless steel pipe is usually used for decoration and industry, the tolerance requirements of pipe diameter size is small, the precision of pipe diameter tolerance is generally more than ±0.1mm. Precision stainless steel pipe is more attention to the tolerance requirements of pipe diameter size, generally controlled within ±0.05mm. 2, the surface treatment is different: stainless steel precision tube surface treatment is more stringent than ordinary stainless steel tube. The surface of the precision stainless steel tube has the following requirements: the surface of the tube body is free from scratches and scars; The wall thickness is uniform and smooth, and the pipe mouth is complete without burrs; The inner wall is smooth, there is no leakage welding trachoma at the weld, and the surface brightness is more than 200 mesh. Usually, the surface of ordinary pipe is rough and needs to be treated twice. In the appearance of the advantage than ordinary stainless steel well more than a little bit. 3, performance is different: ordinary stainless steel pipe commonly used material is generally 201, slightly requirements will use 304,316L almost rarely used. The commonly used material of stainless steel precision tube is generally 304 and 316L, which is more prominent than ordinary stainless steel tube in material performance.
