Metal Udyog (India) is a recognized supplier and exporter of the premium quality Duplex Steel Pipes. We are offering a diverse range of Pipes in various dimensions, shapes, and sizes. We are also customizing them as per the demand of the client. Duplex steel is an exceptionally hardenable alloy. They have excellent resistance to localized corrosion including intergranular, pitting, and crevice corrosion. Their two phase structure consists of a mixture of austenite and ferrite phases. This Duplex Steel Pipes has characteristics of both the steel alloys. Duplex steel is chemically composed of Carbon, manganese, silicon, and many more metals. Generally, Duplex Steel is tougher than the other alloys. The Strength of Duplex Steel Pipes is double as compared to other Pipes. These Pipes are mostly applicable in Chemicals, petrochemicals, Power Generation, Marine, and food processing industries. The Pipes we are designing are according to international standards. Our offered pipes have leak-proof functionality. It comes with added features such as good machinability, excellent durability, and is readily fabricable. Our products are well known for its impeccable features.
Duplex Steel Pipes are also used in Oil and gas exploration and in Pollution control equipment. These pipes are easily wieldable. These Pipes are high in demand due to its robust construction and super finish. Our offered range of Duplex Steel Pipes is extremely corrosion resistant. The pipes have excellent mechanical strength and durability. Our pipes exhibit very high resistance to stress corrosion cracking, even in chloride and sulfide environments. The improved strength of the Duplex Steel Pipes is inherited from the austenitic portion of the structure while its toughness has been inherited from the ferrite portion of the microstructure since the mechanical strength of the alloy is very high.
