Preston Pipes and Alloys is a leading producer, distributor, distributor, and stockiest of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. Stainless Steel 321 alloy is a chromium-nickel steel alloy. Stainless Steel ERW pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, many organic chemicals, and a variety of inorganic chemicals. SS 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The addition of titanium makes it a good solution for high-temperature environments of up to 900 degree C.

We are involved in the production of 321-grade pipes and tubes of various types across India. For instance, 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 which offers a higher temperature strength. These SS 321 Welded Pipes and Stainless Steel 321 Welded Tubes show good welding and forming abilities. Owing to this functionality, they are widely used 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 and chemical processing equipment in Gujarat, India. We manufacture these 321 grades ERW pipes and tubes in different sizes, dimensions, thicknesses, and lengths in Mumbai, India. Apart from the standard sizes, we also produce our pipes and tubes in customized sizes according to our esteemed client’s needs in Rajasthan, India.

The SS Welded 321H Tubes are generally 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 characteristics of these Stainless Steel 321H Welded Pipes make them an exceptional, relatively low-cost choice for a wide variety of applications. We are one of the leading manufacturers of Stainless Steel 321 ERW pipes in Mumbai, India. To ensure the high-quality of our products we perform different tests on our pipes and tubes.

The tests performed include mill test, PMI 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 produce our pipes and tubes, thus manufacturing top-notch quality products.
