Piyush Steels is an established manufacturer, supplier, and distributor of Duplex Steel UNS S31803 Welded Pipes. The Duplex Steel UNS S31803 Welded pipes are high alloy SS that are formed based on the crystalline structure of stainless steels. This steel is nitrogen enhanced and thus offers excellent corrosion resistance over a wide range of temperatures. Moreover, UNS S31803 Duplex Steel Pipes demonstrate high strength, resistance to crevice corrosion and high durability. We offer different forms of Duplex Steel S31803 pipes including Duplex Steel UNS S31803 Seamless Pipes, Duplex Steel UNS S31803 Welded, and Duplex Steel UNS S31803 Cold Drawn Pipes, etc. All these types of pipes are manufactured according to both national and international quality standards. Our Duplex Steel UNS S31803 Welded Pipes are highly demanded in many industries like chemical processing, heat exchangers, food processing, paper & pulp production, boiler industries, oil & refineries, and power generation, Marine engineering, Hydro-carbon processing, Pumps manufacturing, Valves manufacturing, Petrochemical plants, and Nuclear power projects.

Duplex Steel S31803 Welded Pipes

They are stronger and harder than normal steel, but not as challenging to corrosion as stainless steel. These pipes are available in different tailored length sizes, specifications and dimensions. We also manufacture our pipes in custom sizes as per our customer’s demand. The melting point of these welded pipes is 1420 degree Celsius whereas its elongation is 15 %. The mechanical properties of these Duplex steel UNS S31803 Welded pipes are they have tensile strength of Psi – 116000, MPa – 800 and yield strength of Psi – 80000, MPa – 550.To ensure the best quality of our products, we put them to various kinds of tests. Some of the chemical test/ spectro analysis, tests are micro and macro test, intergranular corrosion test, and Mechanical test are the tests are performed in our facility. Other tests are the hardness test, tensile test, flaring test, flattening test, ultrasonic test, positive material test, radiographic test, x-ray test, prompt test, firmness test, pitting corrosion test, and visual inspection. Our team strives hard to manufacture and maintain the high quality standards of our products to meet both national and international standards.
