Martensitic and Austenitic Stainless Steel Tubing is a widely used component of piping in different industries. There are various kinds of stainless steels such as austenitic, duplex and commercially pure metal pipes. steelsupplier Overseas is a manufacturer of Stainless Steel tube in different types, shapes and methods. Our Stainless Steel Seamless Tubes are used in applications that require easy installation and for higher dimensional accuracy. In application where heavy welding is involved, our Heavy Wall Stainless Steel Tubing could be used.

There are different material grades from which the Seamless Stainless Steel Tubing is made. Also, the different manufacturing procedures involved can produce different strengths and capacities of these tubes. The Stainless Steel Welded Tubes can be formed from ½ inches to 24 inches and the SS ERW tubes can come in the same diameter range as well. The electric fusion welded tubes can range from 6 inches to 100 inches. There are also different shapes of the tubes for different applications. The Large Diameter Stainless Steel Tube are used in applications with high pressure systems where the stress at turns is high. It is most common to use the SS Seamless Round Tubes in many applications. We also produce Stainless Steel Thin Wall Tubes for applications with narrow space and high accuracy for less pressure applications. These are also used in measurement equipment in smaller applications. The SS Seamless and the Welded Tubes produced by us are of high quality and are tested carefully. You can get a full product list and don't forget to compare our price list with other SS seamless tube manufacturers China.
