Preston Pipes and Alloys is a prominent producer, supplier, distributor, and exporter 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, 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 solution for high pressure environments of up to 900 degrees Celsius.

We are highly active in the manufacturing of 321-grade pipes and tubes of different types across India. For instance, SS 321 Welded pipes/ tubes, SS 321 ERW Pipes/Tubes, and SS 321 EFW pipes/tubes. SS 321H is a higher carbon version of the 321 grade which provides a higher temperature strength. The SS 321 Welded Pipes and SS 321 Welded Tubes display good welding and forming properties. Owing to this property, these pipes and tubes are used widely in temperatures ranging from greater than 500 degrees C.

The SS 321H pipes are mainly used in the production of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We produce these 321 grades ERW 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 customized sizes according to our valued client’s demand in Rajasthan, India.

The Stainless Steel Welded 321H Tubes are generally 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 affordable option for a wide variety of applications. We, at Preston Pipes and Alloys are one of the best exporters of Stainless Steel 321 ERW pipes in Mumbai, India. To ensure the high-quality of our pipes and tubes we perform various tests on our products.

The tests performed include 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 so on. At Preston Pipes and alloys we use high-end modern technologies to produce our pipes and tubes, hence producing best quality products.
