Preston Pipes and Alloys is a prominent manufacturer, supplier, 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 alloy. Stainless Steel 321 welded pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, various organic chemicals, as well as a variety of inorganic chemicals. SS 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The addition of titanium makes it a good solution for high pressure environments below 900 degree C.

Preston Pipes and Alloys is involved in the production of 321-grade pipes and tubes of varied types across India. They are, 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 offering a higher temperature resistance. The SS 321 Welded Pipes and Stainless Steel 321 Welded Tubes exhibit very good welding and forming capabilities. Owing to this functionality, these pipes and tubes are used widely in temperatures ranging from greater than 500 degrees C.

The SS 321 EFW pipes are mainly applicable in the production 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. Besides the standard sizes, we also manufacture our pipes and tubes in custom sizes according to our esteemed customer’s expectations in Rajasthan, India.

The Stainless Steel Welded 321H Tubes are generally used for 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 characteristics of these Stainless Steel 321H Welded Pipes make them an exceptional, relatively inexpensive option for many applications. We are one of the best exporters of SS 321 ERW tubes in Mumbai, India. To assure the high-quality of our products we perform different tests on the pipes and tubes.

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 more. At Preston Pipes and alloys we use advanced technologies to manufacture our pipes and tubes, thus manufacturing best quality products.
