ASTM A312 Standard

Stainless Steel Pipes

Stainless steel pipes are purely made of steel. These are used in many industries like chemical, petroleum, textiles etc. They are highly resistant to corrosion. These pipes are made by combining chromium nickel and carbon. As the demand is increasing day by day we are providing high quality materials.
