Preston Pipes and Alloys is a leading producer, supplier, distributor, and exporter of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. SS 321 grade is a chromium-nickel steel grade. SS 321 welded pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, various organic chemicals, and a wide range of inorganic chemicals. Stainless Steel 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.

Preston Pipes and Alloys is 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 offering a higher temperature resistance. These SS 321 Welded Pipes and SS 321 Welded Tubes show good welding and forming properties. Due to this property, they are used widely in temperatures ranging from more than 500 degrees C.

Our SS 321 EFW pipes are mainly applicable in the production of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India. We fabricate these 321 grades ERW pipes and tubes in various 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 customer’s needs in Rajasthan, India.

The SS Welded 321H Tubes are generally 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 SS 321H Welded Pipes make them an extraordinary, relatively inexpensive 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.
