Stainless Steel Square Pipe

Stainless steel pipe is a hollow steel material with smooth surface and excellent welding performance. Common materials include 304 and 316. 304 stainless steel is widely used for its balanced performance, while 316 offers superior corrosion resistance in severe environments due to molybdenum. These pipes can be customized in wall thickness and diameter to meet specific industrial requirements.

They are classified into seamless pipes (hot-rolled, cold-rolled, cold-drawn, extruded) and welded pipes (straight seam, spiral). Widely used in petroleum, chemical, medical, food processing, and mechanical instruments.
