Preston Pipes and Alloys is a well-known manufacturer, supplier, supplier, 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 are resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide range of inorganic chemicals. Stainless Steel 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The addition of titanium makes it a good solution for high pressure conditions of up to 900 degrees Celsius.

Preston Pipes and Alloys is involved in the production of 321-grade pipes and tubes of different types across India. They include, 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 providing a higher temperature strength. The Stainless Steel 321 Welded Pipes and SS 321 Welded Tubes display very good welding and forming properties. Owing to this property, they are widely used in operating temperature environments greater than 500 degrees C.

Our Stainless Steel 321 EFW pipes are mainly used in manufacturing of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India. We fabricate these 321 grades ERW 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 client’s needs 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 properties of our SS 321H Welded Pipes make them an exceptional, relatively affordable option for many applications. We are one of the leading exporters of SS 321 ERW tubes in Mumbai, India. To ensure the top-notch quality of our products we perform various tests on the products.

The tests performed are 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. At Preston Pipes and alloys we use advanced technologies to manufacture our pipes and tubes, hence producing top-notch quality products.
