Production Precautions of Cold Drawn Precision Seamless Steel Tubes

In order to ensure the quality of cold drawn precision seamless steel pipe, the production process has a lot of attention. 

Cold drawn precision seamless steel pipe thickness must be uniform, the internal surface defects are less, so the production process need to configure the outer surface and internal defects. In the review process, the re-inspection work is also very critical, so that it can better troubleshoot the poor quality seamless steel pipe. In the production process, the production tool also has a relatively high demand. Annealing is a critical step in the production of cold-drawn precision seamless steel tubes, requires to use an oxidation-free bright annealing facility. Steel pipe manufacturers have some suggestions,such as in the cold drawn precision seamless steel pipe, we can add a certain concentration of salt is very critical.
