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 grade. Stainless Steel ERW 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 choice for high-temperature environments below 900 degree C.

Preston Pipes and Alloys is involved in the production of 321-grade pipes and tubes of various 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. These Stainless Steel 321 Welded Pipes and SS 321 Welded Tubes show very good welding and forming abilities. Due to this functionality, they are used widely in operating temperature environments greater than 500 degrees C.

Our SS 321H pipes are majorly used in manufacturing of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We fabricate these 321 grades welded 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 custom sizes according to our valued customer’s expectations in Rajasthan, India.

Our Stainless Steel Welded 321H Tubes are frequently used for 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 low-cost option for many applications. We are one of the best manufacturers of SS 321 ERW tubes in Mumbai, India. To assure the best quality of our products we perform various tests on the products.

The tests performed are 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 so on. At Preston Pipes and alloys we use advanced technologies to manufacture our pipes and tubes, hence producing high quality products.
