Preston Pipes and Alloys is a prominent producer, distributor, distributor, and stockiest of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. SS 321 alloy is a chromium-nickel steel alloy. SS 321 welded pipes are resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a variety 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 environments below 900 degrees Celsius.

We are highly active in the manufacturing of 321-grade pipes and tubes of various types across India. They are, 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 offers a higher temperature resistance. These Stainless Steel 321 Welded Pipes and Stainless Steel 321 Welded Tubes exhibit very good welding and forming abilities. Owing to this functionality, they are used widely in operating temperature environments more than 500 degrees C.

Our SS 321H pipes are mainly applicable in the production of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We manufacture these 321 grades welded pipes and tubes in many sizes, dimensions, thicknesses, and lengths in Mumbai, India. Apart from the standard sizes, we also produce our pipes and tubes in customized sizes as per our valued client’s demand in Rajasthan, India.

The SS Welded 321H Tubes are frequently 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 characteristics of our Stainless Steel 321H Welded Pipes make them an extraordinary, relatively inexpensive option for many applications. We are one of the best exporters of SS 321 ERW tubes in Mumbai, India. To ensure 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 more. At Preston Pipes and alloys we use advanced technologies to manufacture our pipes and tubes, hence producing top-notch quality products.
