Vipul Pipes and Tubes, located in Chennai, is a reputable producer and supplier of high-performance duplex steel tubing that is designed to offer remarkable strength and resistance to corrosion. Compared to regular stainless steels, duplex stainless steel tubing offers better mechanical qualities and increased durability due to its dual-phase microstructure of austenite and ferrite. Our duplex tubing, which complies with ASTM A789 and A790 standards and is manufactured under strict quality controls, is made for demanding applications in the desalination, oil and gas, chemical processing, and marine industries. These tubes are perfect for crucial piping and structural systems because they guarantee dependability in harsh conditions.
The typical composition of duplex steel tubing is iron, 0.14–0.20% nitrogen, 2.5–3.5% molybdenum, 4.5–6.5% nickel, and 21–23% chromium. High tensile strength (about 620 MPa), superior yield strength (about 450 MPa), and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking are all produced by this composition. In addition to providing dimensional stability at high temperatures and pressures, the duplex microstructure offers good toughness and weldability. Duplex tubing is ideally suited for demanding, critical industrial applications because of these characteristics.

Many industries, such as chemical processing, desalination plants, oil and gas extraction, and marine engineering, use duplex steel tubing because it is long-lasting and resistant to corrosion. Heat exchangers, chemical reactors, pressure vessels, and piping systems subjected to harsh conditions are examples of typical applications. Because of its durability and minimal maintenance needs, duplex tubing is preferred for high-pressure fluid transport systems, offshore platforms, and subsea applications. Long-term operational reliability is ensured by its resistance to chloride stress corrosion, cracking, and pitting, which makes it perfect for use in harsh saline and chemical environments.
