Stainless steel welded pipes are widely used in industries such as petrochemical, pharmaceutical, food, beer and beverage, biochemistry, urban water supply engineering, etc. Due to their high technological content, compared with stainless steel seamless pipes, they have the characteristics of wide product coverage, uniform wall thickness, high accuracy, smooth and flat inner walls, no pits, and good quality. The internal polishing finish is less than or equal to 0.2-0.6um metal smooth, which is a high-quality material for stainless steel fluid steel pipes. We take this opportunity to thank all new and old customers for their support and patronage!
