PRODUCT DESCRIPTION

 PRODUCT INTRODUCTION

Stainless steel seamless pipe is a hollow steel made by hot rolling or cold drawing through perforation. Seamless pipe has excellent corrosion resistance, high strength and good mechanical processing performance. Due to the weld-free connection structure and hollow section, it is superior to welded steel pipe in terms of pressure bearing capacity, crack resistance and service life. It is widely used in high-standard fields such as petrochemical, boiler heat exchangers, food equipment, pharmaceutical machinery, aerospace and architectural decoration. The surface of seamless stainless steel pipe is smooth and the dimensional accuracy is high. It is suitable for working environments with strict requirements on fluid transport cleanliness and high-pressure corrosion resistance. According to different needs, stainless steel seamless pipes that require international standards can be selected. We can not only provide a variety of surface treatment methods such as pickling, polishing, and wire drawing, but also can be customized according to the outer diameter range of the steel pipe from 6mm to 630mm, the wall thickness ranges from 0.5mm to 30mm, and the length is also customized according to customer requirements, usually 1 to 12 meters.
