SA 789 UNS S32205 Seamless Tube and UNS S31803 Duplex Pipe supplier in China

The Duplex 2205 Pipe is made with a high concentration of nickel, chromium, and ferrous in their composition. These pipes are resistant to corrosion and erosion in different mediums. The products from this grade are neither fully austenitic nor ferritic. A duplex 2205 Tube can be easily machined and fabricated. These tubes show excellent resistance against crevice corrosion, sulfide ion cracking, and pitting due to various acids. The duplex stainless steel Pipe is designed with superior strength and enhanced hardness. These pipes possess a minimum tensile strength of 95Ksi and a minimum yield strength of 65Ksi. They can be elongated by 15% in different applications. The 22cr Duplex Pipe has a density of 7.8g/cm3 and is manufactured following all international and national standards. These pipes are available in nominal sizes of ½ NB to 12 NB. The Astm A790 Uns S32205 is equivalent to the duplex grade. This grade is produced under the guidance of our experienced staff. It is annealed after the hot-rolling process to give it enhanced hardness. We are the leading Duplex Pipe suppliers in China. Our institution aims to supply high-quality products through all our outlets across the country. Our experienced workers make use of the latest technology and the best 2205 Pipe Material to produce the best products in the market.


The Duplex 2205 Seamless Pipe is made from a single piece of steel. This gives it enhanced strength and excellent tolerances in stress-induced environments. They are available in lengths between 4mm to 219mm. A Duplex 2205 Welded Pipe is manufactured by welding pieces of steel either spirally or longitudinally. These pipes are cost-effective and possess a thickness between 0.5mm to 20mm and lengths up to 1219.2mm. The 2205 Duplex Stainless Pipe exhibits magnetic properties in certain environments. These pipes are available in plain, beveled and threaded tubing ends. The 2205 Pipe Sizes are available in single random, double random, and cut lengths. These pipes are produced in rectangular, circular, square, u-lop, and other shapes. In the Astm A790 Uns S31803 grade pipes and tubes can be cold-rolled to give them enhanced properties and good resistances in different systems. They are very versatile in different applications. The 2205 SS Pipe is widely used in chemical processing, offshore drilling, oil and gas refining, cooling systems, pollution control equipment, marine environments, etc. Alloy 2205 Pipe has a melting point of 1350 degrees C. These pipes have a wall thickness between 0.3mm to 50mm.
