Preston Pipes and Alloys is a notable manufacturer, distributor, supplier, and exporter of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. SS 321 alloy is a chromium-nickel steel grade. SS 321 welded pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, various organic chemicals, as well as a variety of inorganic chemicals. Stainless Steel 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The titanium content makes it a good option for high pressure environments of up to 900 degrees Celsius.

We are involved in the production of 321-grade pipes and tubes of different 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 high carbon version of the 321 grade which offers a higher temperature strength. The Stainless Steel 321 Welded Pipes and SS 321 Welded Tubes display very good welding and forming capabilities. Owing to this functionality, these pipes and tubes are widely used in temperatures ranging from greater than 500 degrees C.

Our SS 321 EFW pipes are mainly applicable in manufacturing of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We produce these 321 grades EFW 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 esteemed client’s demand in Rajasthan, India.

The SS Welded 321H Tubes are usually used in applications that require heating temperature in the range of 800 degrees F and 1650 degree F, for example, 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 affordable choice for many applications. We, at Preston Pipes and Alloys are one of the best exporters of Stainless Steel 321 ERW pipes in Mumbai, India. To assure the best quality of our products we perform different tests on the products.

The tests performed are 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 so on. We use high-end modern technologies to manufacture our pipes and tubes, hence producing high quality products.
