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

We are involved in the manufacturing of 321-grade pipes and tubes of varied types across India. They include, SS 321 Welded pipes/ tubes, SS 321 ERW Pipes/Tubes, and SS 321 EFW pipes/tubes. SS 321H is a high carbon version of the 321 grade providing a higher temperature resistance. The SS 321 Welded Pipes and Stainless Steel 321 Welded Tubes exhibit good welding and forming properties. Owing to this functionality, they are used widely in temperatures ranging from more than 500 degrees C.

Our SS 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 EFW pipes and tubes in different 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 expectations in Rajasthan, India.

Our SS Welded 321H Tubes are usually used in applications that require heating temperature between 800 degrees F and 1650 degree F, for example, aircraft collector rings, exhaust manifolds, expansion joints, and high-temperature chemical process equipment. The overall properties of our Stainless Steel 321H Welded Pipes make them an extraordinary, relatively low-cost choice for many applications. We are one of the best manufacturers of Stainless Steel 321 ERW pipes in Mumbai, India. To ensure the high-quality of our pipes and tubes we perform different tests on the 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 high-end modern technologies to manufacture our pipes and tubes, hence manufacturing high quality products.
