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. Stainless Steel 321 alloy is a chromium-nickel steel grade. Stainless Steel 321 welded pipes are resistant to atmospheric corrosion, sterilizing solutions, various 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 option for high-temperature conditions below 900 degree C.
Preston Pipes and Alloys is highly active in the manufacturing 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.Stainless Steel 321H is a high carbon version of the 321 grade offering a higher temperature resistance. These SS 321 Welded Pipes and SS 321 Welded Tubes show good welding and forming abilities. Owing to this functionality, these pipes and tubes are widely used in temperatures ranging from greater than 500 degrees C.
The SS 321H pipes are mainly used in manufacturing of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India. We produce these 321 grades welded 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 esteemed client’s expectations in Rajasthan, India.
Our SS Welded 321H Tubes are generally 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 characteristics of these Stainless Steel 321H Welded Pipes make them an extraordinary, relatively inexpensive option for many applications. We are one of the best manufacturers of Stainless Steel 321 ERW pipes in Mumbai, India. To ensure the best quality of our products we perform different 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. We use advanced technologies to produce our pipes and tubes, hence producing top-notch quality products.
