"quality is the only way to survive'is what we always believe.we have a strict quality control system in our factory.all steel products need to pass strict quality testing before leaving the factory for sale. if needed, sgs testing or other third-party testing could be arranged for you.we have aggressive growth plans for the future and hope that you will consider partnering with us to help keep a healthy manufacturing base thriving in the world. Production processThe production process of stainless steel pipes is mainly divided into three steps1. Steel sintering: Sintering stainless steel raw materials (carbon steel or alloy steel) into stainless steel materials after heat treatment to achieve the required properties, which are the most critical characteristics of stainless steel. Sintered steel is mainly added with additives such as ore powder, small stones, sodium silicate, etc., and then heated and melted before cooling2. Stretching processing: After stretching processing, stainless steel materials are formed, usually through two processes of cold and hot drawing, resulting in good material quality, smooth surface, and high accuracy.3. Heat treatment: Apply appropriate heat treatment to the stretched stainless steel material to increase its corrosion resistance, wear resistance, tensile strength, and other characteristics, in order to ac
