Preston Pipes and Alloys is a notable 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 ERW pipes are resistant to atmospheric corrosion, 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 titanium content makes it a good option for high-temperature environments of up to 900 degree C.

We are involved in the manufacturing 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. SS 321H is a higher carbon version of the 321 grade which provides a higher temperature strength. The Stainless Steel 321 Welded Pipes and Stainless Steel 321 Welded Tubes show very good welding and forming abilities. Owing to this functionality, they are used widely in operating temperature environments greater than 500 degrees C.

Our SS 321 EFW pipes are mainly applicable in the production of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India. We produce these 321 grades ERW 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 client’s demand in Rajasthan, India.

Our 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 properties of these SS 321H Welded Pipes make them an extraordinary, relatively inexpensive choice for many applications. We are one of the leading exporters of Stainless Steel 321 ERW pipes in Mumbai, India. To assure the high-quality of our products we perform different tests on the 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 so on. We use advanced technologies to produce our pipes and tubes, hence producing top-notch quality products.
