Rithav Pipes and Tubes is a prominent manufacturer and supplier of Super Duplex Steel EFW (Electric Fusion Welded) Pipes, with its base in Delhi, India. We deal in providing high-quality piping solutions designed for strength, longevity, and superior corrosion resistance. Our Super Duplex EFW pipes are manufactured through advanced electric fusion welding processes, which provide weld quality consistency and dimensional accuracy. Suitable for pressure and corrosive conditions, these pipes are used in industries like oil and gas, chemical processing, and marine engineering. Rithav Pipes and Tubes is recognized for guaranteed service, timely delivery, and compliance with national and international quality standards.
Super Duplex Steel EFW Pipes are generally made up of approximately 25% chromium, 7% nickel, 4% molybdenum, and the addition of nitrogen and manganese. This composition of alloy exhibits excellent resistance to pitting, crevice corrosion, as well as stress corrosion cracking. Mechanically, these pipes have a high tensile strength of about 750 MPa and a yield strength of about 550 MPa. The electric fusion welding process provides excellent weld integrity and performance for stringent applications. The microstructure of ferrite and austenite phases helps to show excellent strength, toughness, and resistance to corrosion in high temperature and high pressure conditions.
