Preston Pipes and Alloys is a respected producer, distributor, supplier, and stockiest of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. SS 321 alloy is a chromium-nickel steel alloy. Stainless Steel ERW pipes are resistant to atmospheric corrosion, 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 choice for high-temperature conditions below 900 degrees Celsius.

Preston Pipes and Alloys is highly active in the production 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.Stainless Steel 321H is a higher carbon version of the 321 grade offering a higher temperature resistance. The Stainless Steel 321 Welded Pipes and Stainless Steel 321 Welded Tubes display very good welding and forming properties. Due to this functionality, these pipes and tubes are used widely in operating temperature environments more than 500 degrees C.

The SS 321 EFW pipes are mainly applicable in manufacturing of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India. We produce these 321 grades EFW pipes and tubes in many sizes, dimensions, thicknesses, and lengths in Mumbai, India. Besides the standard sizes, we also produce our pipes and tubes in custom sizes as per our esteemed customer’s demand in Rajasthan, India.

Our 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 instance, aircraft collector rings, exhaust manifolds, expansion joints, and high-temperature chemical process equipment. The overall properties of these Stainless Steel 321H Welded Pipes make them an extraordinary, relatively low-cost choice for many applications. We are one of the best manufacturers of SS 321 ERW tubes in Mumbai, India. To ensure the high-quality of our products we perform various tests on our 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 more. We use high-end modern technologies to produce our pipes and tubes, thus manufacturing high quality products.
