Preston Pipes and Alloys is a leading producer, distributor, supplier, and exporter of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. SS 321 grade is a chromium-nickel steel grade. SS 321 welded pipes are resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, as well as a variety of inorganic chemicals. SS 321 Welded Tubes is a common austenitic 18/8 stainless steel alloy. The addition of titanium makes it a good choice for high pressure conditions below 900 degrees Celsius.
We are involved in the production of 321-grade pipes and tubes of varied types across India. They are, SS 321 Welded pipes/ tubes, SS 321 ERW Pipes/Tubes, and SS 321 EFW pipes/tubes.Stainless Steel 321H is a higher carbon version of the 321 grade offering a higher temperature resistance. These SS 321 Welded Pipes and Stainless Steel 321 Welded Tubes show very good welding and forming capabilities. Owing to this functionality, they are used widely in operating temperature environments greater than 500 degrees C.
Our Stainless Steel 321 EFW pipes are majorly used in manufacturing of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We fabricate these 321 grades EFW pipes and tubes in many sizes, dimensions, thicknesses, and lengths in Mumbai, India. Apart from the standard sizes, we also produce our pipes and tubes in custom sizes as per our esteemed client’s requirement in Rajasthan, India.
Our SS Welded 321H Tubes are frequently used for applications that require heating temperature between 800 degrees F and 1650 degree F, for instance, aircraft collector rings, exhaust manifolds, expansion joints, and high-temperature chemical process equipment. The overall properties of these Stainless Steel 321H Welded Pipes make them an exceptional, relatively low-cost choice for a wide variety of applications. We, at Preston Pipes and Alloys are one of the leading exporters of SS 321 ERW tubes in Mumbai, India. To ensure the high-quality of our products we perform various tests on the products.
The tests performed include mill test, Positive Material Identity test, product analysis, transverse tension test, etching test, radiographic examination, grain size test, hardness test, bend test, flare test, stabilizing heat treatment, intergranular corrosion test and more. At Preston Pipes and alloys we use advanced technologies to manufacture our pipes and tubes, thus manufacturing top-notch quality products.
