Duplex 2205 Pipe

Products We Offer

Duplex 2205 Pipe

Duplex products are produced with a mixture of ferritic and austenitic steel. A  Duplex 2205 Pipe has a high chemical composition of chromium, molybdenum, and nickel. This gives these pipes superior corrosion and erosion resistance properties. They are very strong and designed with a density of 7.8 g/cm3. The ASTM A790 UNS S32205 tube has superior mechanical properties and exceptional strength. These tubes have a minimum tensile strength of 116000 Psi and minimum yield strength of 8000 Psi. The 2205 Duplex Stainless Steel Tubing can be easily elongated by 15%. They have a melting point of 1350 degrees C. These tubings are available in standard sizes up to 152mm OD which can be customized on request. Alloy 2205 Tube is a preferred choice in petrochemical systems, chemical industries, pulp, and paper processing, etc. We follow all industry standards and perform tests necessary for all 2205 pipe supplier in India. Our high-quality products can be availed at reasonable prices.

A Duplex 2205 Seamless Pipe is produced with a single sheet metal making it very strong. The absence of any welds or seams enables them to suffice in stress-induced environments for long periods. The Duplex 2205 Seamless Tube makes use of the best material which makes it a little costly. These tubes possess a hardness of 31 Rockwell. They are available in sizes between 15NB to 150NB. An Alloy 2205 Welded Pipe is a cost-effective alternative to the seamless pipes. These pipes are highly reliable in different systems. They are available in sizes between 5mm to 1219.2mm. The 22 cr Stainless Steel ERW Pipe is cold-rolled to give them desired properties. These pipes are used in applications for low and high-frequency systems. They can be availed in single random, double random, and cut lengths. Duplex Steel 2205 EFW Pipe is highly versatile and produced via the electrofusion process.

The Duplex S31803 Pipe possesses high strength and can be readily fabricated or machined. These pipes possess excellent stress-corrosion resistance in different environments. The UNS S31803 Duplex Stainless Steel Pipe has superior fatigue strength and possesses excellent workability. These pipes are available in sizes ranging between 1/2NB to 16NB. The UNS S31803 Seamless Material is made with a thickness between SCH 5 to SCH 160 and SCH XXS. They can be availed in square, circular, hollow, and other shapes. We are the Duplex 2205 Pipe distributors who can customize all our products in a short period to fulfill all your requirements. Our products are properly sealed and wrapped before delivery.
