Stainless steel pipe production categories

Stainless steel pipes are usually divided into stainless steel seamless pipes and stainless steel seam welded pipes:
   In the production process of stainless steel seamless pipes, the steps of perforation, cold drawing (cold rolling), and inspection are key links in the entire process. Correspondingly, punching machines, pipe drawing machines, pipe rolling machines and various testing equipment play a decisive role in the entire production process. The rolling specifications of the unit are second to none in the world and have greatly promoted the development of China's seamless steel pipe production equipment and the progress of the giant-diameter seamless steel pipe market.
  In the production process of stainless steel welded pipes, the forming and welding parts are the main processes for turning the plate (strip) into a round pipe. In the welding process, the most common welding equipment is straight seam high-frequency welding equipment, straight seam double-sided welding process and spiral submerged arc welding process. At present, stainless steel pipe products are generally polished during the production process, and only a few products such as water heaters, water dispenser linings, etc. do not require polishing. Therefore, this requires good polishing properties of the raw material.
