Duplex Steel Pipes & Tubes

Turnon Alloys is one of the most trusted names among Duplex Steel Pipes & Tubes Manufacturers, offering durable, high-performance piping solutions for industries demanding superior strength and corrosion resistance. Duplex steel is a family of stainless steels that features a dual-phase microstructure of austenite and ferrite, which results in outstanding mechanical properties and enhanced corrosion resistance. These pipes and tubes are widely used in the chemical industry, petrochemical plants, offshore oil rigs, and seawater equipment due to their excellent durability and resistance to pitting and crevice corrosion.

What sets Duplex Steel Pipes & Tubes apart is their unique combination of high tensile strength, good weldability, and excellent resistance to various forms of corrosion. They are particularly effective in chloride-bearing environments, making them a preferred material in marine and saltwater applications. Turnon Alloys supplies these pipes and tubes in compliance with ASTM A790 and ASME SA790 standards, ensuring exceptional performance and quality across all applications. Our range includes both seamless and welded variants, offering flexibility for a wide range of industrial and commercial uses.

As experienced Duplex Steel Pipes & Tubes Suppliers, Turnon Alloys guarantees materials that conform to the highest international quality benchmarks. One of the major benefits of using Duplex steel is its high yield strength—nearly double that of standard austenitic stainless steels—which leads to weight savings in structural applications and lower material costs. The superior mechanical properties also reduce maintenance needs and increase the lifecycle of the installation. Duplex steel’s high chromium and molybdenum content ensures long-term performance even under extreme conditions.

Turnon Alloys is also recognized among global Duplex Steel Pipes & Tubes Stockists, maintaining a comprehensive inventory of all standard sizes and specifications to fulfill urgent project demands. Our expert logistics capabilities enable timely shipping to various parts of the world. Our products are thoroughly inspected and tested, meeting both ASTM A790 and ASME SA790 standards, which are globally recognized for seamless and welded duplex stainless steel pipes.
