Preston Pipes and Alloys is a well-known 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 321 welded pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, various organic chemicals, and 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 option for high-temperature conditions of up to 900 degree C.

Preston Pipes and Alloys is involved 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 which provides a higher temperature strength. These SS 321 Welded Pipes and Stainless Steel 321 Welded Tubes show good welding and forming properties. Owing to this functionality, these pipes and tubes are widely used in operating temperature environments more than 500 degrees C.

Our Stainless Steel 321 EFW 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 customized 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 properties of our Stainless Steel 321H Welded Pipes make them an exceptional, relatively low-cost choice for many applications. We, at Preston Pipes and Alloys are one of the leading exporters of SS 321 ERW tubes in Mumbai, India. To ensure the high-quality of our pipes and tubes we perform various tests on our pipes and tubes.

The tests performed include 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 produce our pipes and tubes, thus producing top-notch quality products.
