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

We are involved in the production of 321-grade pipes and tubes of varied 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 which offers a higher temperature strength. The Stainless Steel 321 Welded Pipes and Stainless Steel 321 Welded Tubes display very good welding and forming abilities. Due to this property, they are widely used in operating temperature environments more than 500 degrees C.

The SS 321 EFW pipes are majorly used in the production of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We fabricate these 321 grades EFW pipes and tubes in different sizes, dimensions, thicknesses, and lengths in Mumbai, India. Besides the standard sizes, we also manufacture our pipes and tubes in custom sizes as per 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 SS 321H Welded Pipes make them an exceptional, relatively affordable choice for a wide variety of applications. We are one of the leading manufacturers of SS 321 ERW tubes in Mumbai, India. To assure the top-notch quality of our products we perform different tests on the products.
