Precision stainless steel pipes and industrial grade stainless steel seamless pipe can be compared from the following aspects 1, industrial-grade stainless steel tube material is stainless steel tube, ie mother pipe, cold drawn or cold rolled after annealing and pickling is not finished stainless steel seam tube. The main features of industrial grade stainless steel seamless pipe is without welding seam, can withstand greater pressure, but through solid steel surface melting process (that is, we usually say that the annealing treatment) pipe can be bent, reaming and other processing. 2, precision stainless steel tube products emerged in recent years, mainly in the hole, the outer dimensions with tight tolerances, surface finish and steel have high demands. Precision stainless steel tube 1. The outer diameter of the smaller features, in general, precision stainless steel tube outer diameter of 6 mm or more in general, Wenzhou Renault tube can produce diameter 6-133 mm steel pipe. High precision can do small batch production, I plant the production of precision stainless steel tube finishing MOQ is 500KG, and special sizes and requirements can also be customized, the production of precision stainless steel pipe to meet the special requirements of different users. 3. Accuracy of relatively high precision stainless steel pipe, steel pipe and the bore diameter tolerance 6-60 of the general control within plus or minus 3-5 silk. 4. surface finish good precision stainless steel tube, inside and outside surfaces of the tube finish Ra≤0.8μm, can make to the wall thickness of 0.5mm. Then polished inner and outer surfaces of the tube finish up Ra≤0.2-0.4μm (such as a mirror). 5 steel pipe superior performance, the metal is relatively dense, steel can withstand the pressure becomes larger. In short: precision stainless steel tube is for further processing in the general industrial grade stainless steel tube, precision and smoothness in the obvious strengths, but its cost is relatively teach high, high-end stainless steel tube.
