Preston Pipes and Alloys is a leading manufacturer, supplier, supplier, and stockiest of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. Stainless Steel 321 alloy is a chromium-nickel steel grade. SS 321 welded pipes are resistant to atmospheric corrosion, sterilizing solutions, various organic chemicals, as well as a wide range 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 of up to 900 degrees Celsius.

We are involved in the production of 321-grade pipes and tubes of varied 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 provides a higher temperature strength. These Stainless Steel 321 Welded Pipes and Stainless Steel 321 Welded Tubes show very good welding and forming properties. Owing to this functionality, these pipes and tubes are widely used in operating temperature environments greater than 500 degrees C.

Our Stainless Steel 321 EFW pipes are mainly used in the production of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India. We manufacture these 321 grades welded pipes and tubes in various sizes, dimensions, thicknesses, and lengths in Mumbai, India. Besides the standard sizes, we also produce our pipes and tubes in custom sizes according to our esteemed customer’s demand in Rajasthan, India.

The Stainless Steel Welded 321H Tubes are usually used for applications that require heating temperature in the range of 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 our Stainless Steel 321H Welded Pipes make them an extraordinary, relatively low-cost choice for many applications. We, at Preston Pipes and Alloys are one of the leading manufacturers of SS 321 ERW tubes in Mumbai, India. To ensure the best quality of our pipes and tubes we perform different tests on the pipes and tubes.

The tests performed are flattening 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 produce our pipes and tubes, hence producing high quality products.
