Duplex Pipe

ASTM A790 Seamless Tubes and Duplex Steel Tube Supplier in India

Duplex Pipe

Great Steel & Metals is an ISO certified Duplex Pipe suppliers and we stock Duplex steel tubes in many sizes and wall thicknesses. Duplex is an alloy material that has austenitic and ferritic steel phases in its metallurgic structure. The combination allows for the duplex steel to perform in strength and corrosion resistance properties. The Duplex Stainless Steel Seamless Pipe is cold drawn and it could be used in a number of applications that require excellent corrosion resistance, wear and tear resistance, strength and accuracy in dimensions. We manufacture the standard duplex, super duplex and lean duplex grade pipes for uses in all industries. The ASTM A790 Duplex Tube can be seamless or straight-seam steel pipes that are used in high temperature applications. The specialty of this particular grade of duplex is that it could perform under high temperatures for a prolonged period of time without the risk of oxidation. The extended use may cause embrittlement in some grades. The ASME SA790 Duplex Stainless Steel Tubing applications therefore limit the time of exposure to high temperatures depending on the nature, standards, pipe sizes and pressure classes of the pipes used. The pipes could be heated treated for additional strength. The SS Duplex Seamless Tube produced by us are of high quality. We produce the electric resistance welded Stainless Duplex Erw Pipes for better performance. We offer a wide range of products in other grades as well. We can offer the product details upon inquiry.
