Preston Pipes and Alloys is a respected manufacturer, supplier, supplier, and exporter of Stainless Steel 321, 321H Welded (ERW, EFW) Pipes/Tubes in Mumbai, India. Stainless Steel 321 alloy is a chromium-nickel steel alloy. Stainless Steel ERW pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, various organic chemicals, as well as a variety of inorganic chemicals. Stainless Steel 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The titanium content makes it a good choice for high-temperature environments below 900 degrees Celsius.
Preston Pipes and Alloys is involved 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. SS 321H is a high carbon version of the 321 grade which provides a higher temperature resistance. These SS 321 Welded Pipes and SS 321 Welded Tubes exhibit very good welding and forming properties. Owing to this property, these pipes and tubes are used widely in temperatures ranging from more than 500 degrees C.
The SS 321 EFW pipes are mainly applicable in manufacturing of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India. We fabricate 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 valued client’s demand in Rajasthan, India.
The 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 properties of these Stainless Steel 321H Welded Pipes make them an extraordinary, relatively inexpensive option for a wide variety of applications. We, at Preston Pipes and Alloys are one of the best manufacturers of Stainless Steel 321 ERW pipes in Mumbai, India. To assure the best quality of our pipes and tubes we perform different tests on the pipes and tubes.
The tests performed include mill test, Positive Material Identity 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, thus manufacturing best quality products.
