Is a prominent manufacturer, supplier, and distributor of Duplex Steel UNS S31803 EFW Pipes. EFW steel pipe stands for Electric Fusion Welding steel pipe and refers to an electron beam welding. They are characterized by high chromium ranging from 19 percent to 32 percent and molybdenum ranging up to 5 percent and lower nickel contents. These Duplex Steel UNS S31803 EFW Pipes are the best combination of the resistance and the stress corrosion, cracking, pitting, and crevice corrosion. It also has the property of high and longevity. These EFW pipes are used in various industries like the oil industry, gas industry, refrigeration, filtration, petrochemical, and also the industry offshore. They are also used in the large industries such as Oil & Gas industry, Chemical industry, Fertilizer industry, Refinery industry, Petrochemical industry, Power industry, automotive industry, as well as in Bearing, Mechanical & Structural appliances.

The properties of these duplex stainless steels are achieved by means of having an overall lower alloy content making them cost-effective for many applications. We offer these pipes in customized thicknesses, specifications and sizes as per the précised requirements given by our valuable customers in international quality of standards. The melting point of these EFW pipes is 1420 degree Celsius whereas its elongation is 15 %. The mechanical properties of these Duplex steel UNS S31803 EFW 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.
