Super Duplex Steel Pipe & Tube

Super Duplex Steel Pipe & Tube

Kobs India are reputed manufacturers, traders, and exporters of Super Duplex Steel Pipe & Tube all over the world.

Super Duplex is stainless steel mainly used in oil and gas industries. Super Duplex alloys are characterised by a high chromium and molybdenum content. This provides high tensile strength which helps it to have a better resistance to corrosion, cracking as well as erosion, and having a high thermal conductivity and a low thermal expansion than conventional austenitic stainless steels. The high chromium and molybdenum content gives Super Duplex Steel a high resistance to acids that prevents it from pitting and crevice corrosion.

These unique properties of Super Duplex are the reasons for its high demand for a wide range of scenarios such as pipes in the oil and gas industry, utility and industrial systems, high strength wiring solutions, structural and mechanical components, cargo vessels and heat exchangers. It is suitable to use in many offshore and onshore applications.
