Duplex Steel Pipes and Tubes are called as "duplex", for the reason that they have a two-parcel microstructure that contains grains of austenitic and ferritic steel. Right when Duplex steel is being disintegrated it hardens from the liquid section to a totally ferritic course of action. As the material gets chill off to room temperature, approximately half of the ferritic grains make over to austenitic grains ("islands"). In light of present circumstances, the outcome is a microstructure of around 50 percent of austenite and 50 percent of ferrite. Super Duplex Steels are by and large twice as extreme as standard austenitic or ferritic steels.


We are possessed with offering an unparalleled social affair of Copper Alloy Pipes and Tubes. With tremendous experience and an able gathering of work constrain, this extent of copper mix is improved utilizing survey nickel and copper compound than certification its dimensional precision, disintegration resistance and perfect quality. Despite this, the offered range is fitting in different territories, for instance, oil and gas, exhausting and well building and creation ventures.

Rameshwar Metal India are included with amassing and suppling a broad assortment of Duplex Steel Pipes that are extensively utilized as a bit of headway and differing associations. These duplex steel channels have high resistance against usage and are open in different evaluations and conclusions. Our degree of duplex steel pipes and tubes are quality endeavored on different parameters before being passed on to customers. Offered at industry driving costs, these are moreover changed by particular necessities of customers.
