Duplex Steel S31803 and S32205 Pipes and Tubes Manufacturer and Supplier

Duplex Steel UNS S31803 and UNS S32205 are Duplex 2205 Duplex 2205 is a combination of austenitic and ferritic structures with the aim of providing high strength and very good resistance to pitting and stress corrosion cracking. Oil and gas pipelines, offshore platforms, desalination plant, chemical processing plant, heat exchanger and marine engineering are other applications in which these grades of pipes and tubes can be found in the presence of chloride rich and high pressure environments.

Duplex Steel S31803 and S32205 pipes and tubes are more promising yield strength, localized corrosivity and fatigue capabilities than stainless steel 304 or 316. This enables the designers to employ thinner wall sections with the same pressure rating. Duplex microstructure is also providing better resistance to stress corrosion cracking in chloride environments such that these grades are the best in aggressive process media.

Duplex Steel UNS S31803 and UNS S32205 pipes and tubes provided by Aashish Metals are produced under the international standards, including ASTM A790 as far as seamless and welded pipes are concerned, and ASTM A789 concerning seamless and welded tubes. DIN 1.4462 and other simulations can also be provided with material as per project requirement, together with test certificates, heat numbers and full documentation to trace.

Aashish Metals is the company dealing with a variety of Duplex Steel S31803 and S32205 products such as seamless pipes, welded pipes, ERW tubes, EFW pipes, seamless tubes and fabricated piping. They come in round shape, square and rectangular shapes with various schedules and thicknesses. This product mix enables the engineer and purchaser to choose the best Duplex Steel pipes and tubes to use in the processes piping, structural support structures and heat transfer equipment.

Duplex steel UNS S31803 and UNS S32205 pipes and tubes are subjected to quality control by strictly choosing material, manufacturing control and extensive testing. The batches are inspected in terms of chemical structure, mechanical properties, sizes, and finish. On request, non destructive testing including hydrostatic and ultrasonic can be done. Third party inspection and packaging to be exported plus mill test certificates ensures reliability between the mill and the site.

Yes, Duplex Steel S31803 and S32205 pipes and tubes are made to be particularly used in harsh high temperature and corrosive conditions. They are efficient in the media that has chlorides, organic acids and seawater where traditional stainless steel would not work. Common uses are heat exchangers, evaporators, riser pipes, subsea flowlines and process equipment in a refinery and petrochemical plant. Using appropriate grade and design will enable the product to have a long service life and minimal maintenance.

Aashish Metals delivers Duplex Steel UNS S31803 and UNS S32205 pipes and tubes within a wide size. Outer diameters encompass small bore to large bore diameter with a light gauge to heavy schedule of SCH 10 to SCH 160. They are available in standard lengths, random lengths, and also cut to size parts may be provided upon specific project requirements, so that the material use and fabrication time are optimised.
