Preston Pipes and Alloys is a prominent manufacturer, distributor, supplier, and exporter of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. Stainless Steel 321 grade is a chromium-nickel steel alloy. SS 321 welded pipes are resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, as well as a variety of inorganic chemicals. SS 321 Welded Tubes is a common austenitic 18/8 stainless steel alloy. The addition of titanium makes it a good choice for high-temperature environments of up to 900 degrees Celsius.

Preston Pipes and Alloys is highly active in the production 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 SS 321 Welded Pipes and SS 321 Welded Tubes display good welding and forming properties. Owing to this functionality, they are used widely in operating temperature environments more than 500 degrees C.

Our Stainless Steel 321 EFW pipes are mainly applicable in manufacturing of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We fabricate these 321 grades ERW pipes and tubes in many sizes, dimensions, thicknesses, and lengths in Mumbai, India. Apart from the standard sizes, we also manufacture our pipes and tubes in customized sizes as per our esteemed customer’s expectations in Rajasthan, India.

The Stainless Steel Welded 321H Tubes are usually used in applications that require heating temperature in the range of 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 choice for many applications. We are one of the leading manufacturers of Stainless Steel 321 ERW pipes in Mumbai, India. To ensure the top-notch quality of our products we perform various tests on our pipes and tubes.

The tests performed include flattening 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 high-end modern technologies to manufacture our pipes and tubes, hence producing best quality products.
