Stainless Steel Welded Tube

Stainless steel welded pipes and tubes are produced by forming stainless steel strip or plate into a tubular shape and joining the edges by welding to create a longitudinal seam.

They can be supplied in a wide range of sizes and in long continuous lengths, making them ideal for continuous-flow applications.

Welded stainless steel tubing is widely used under moderate pressure, temperature, and corrosive conditions, especially in food & beverage, automotive, architectural and structural, water treatment, and general industrial systems.
