Preston Pipes and Alloys is a notable manufacturer, supplier, distributor, and exporter 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 have high corrosion resistance to atmospheric conditions, sterilizing solutions, many 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 choice for high-temperature conditions of up to 900 degree C.

We are highly active in the production of 321-grade pipes and tubes of various types across India. They include, SS 321 Welded pipes/ tubes, SS 321 ERW Pipes/Tubes, and SS 321 EFW pipes/tubes.Stainless Steel 321H is a high 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 capabilities. Due to this property, these pipes and tubes are widely used in temperatures ranging from more than 500 degrees C.

The SS 321H pipes are majorly applicable 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 according to our valued client’s expectations in Rajasthan, India.

Our SS Welded 321H Tubes are generally used for applications that require heating temperature between 800 degrees F and 1650 degree F, for instance, aircraft collector rings, exhaust manifolds, expansion joints, and high-temperature chemical process equipment. The overall characteristics of these SS 321H Welded Pipes make them an exceptional, relatively affordable option for many applications. We are one of the best exporters of Stainless Steel 321 ERW pipes in Mumbai, India. To assure the best quality of our pipes and tubes we perform various tests on our pipes and tubes.

The tests performed include flattening 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 advanced technologies to manufacture our pipes and tubes, thus manufacturing top-notch quality products.
