Vipul Pipes and Tubes is a reliable partner for advanced tubing needs in India and international markets, with an emphasis on quality, prompt delivery, and customer satisfaction.
Grades such as UNS S32750 and S32760 are commonly found in Super Duplex Steel Tubing, which has a balanced composition of approximately 25% chromium, 7% nickel, 3-4% molybdenum, and nitrogen. Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking is offered by this dual-phase (austenitic-ferritic) alloy. With a yield strength of about 550 MPa and a tensile strength of about 800–1000 MPa, it provides excellent mechanical strength. It is perfect for harsh environments due to its exceptional fatigue strength and impact resistance. In addition to providing good weldability and workability, the tubing continues to perform exceptionally well in corrosive, high-pressure, and high-temperature applications.
