Recently, after three months of unremitting efforts of our colleagues, we have successfully delivered specifications to foreign customers: 812mm×7.92mm×6000mm large-diameter seamless thin-walled stainless steel pipe. Since the company began to transform in 2009, it has led the production of high-precision mechanical engineering standards. The stainless steel tubing was changed to research and production of thin-walled stainless steel seamless steel pipe. After ten years of continuous innovation and improvement, we are mature in the field of large-diameter thin-walled seamless stainless steel tube processing and manufacturing, and always maintain the leading domestic level. From the original production of thin-walled seamless pipes with a wall thickness of sch10s, it is now possible to produce sch5s, etc., from the beginning of the production of thin-walled tubes of austenitic materials, and now overcome the problem of cracking in thin-walled stainless steel pipes during cold drawing. It can produce super duplex stainless steel thin-walled tubes with higher strength and hardness, and thin-walled tubes of nickel-based alloy materials. To this end, we will continue to improve and work hard to provide customers with better stainless steel pipes and fittings.
