Stainless Steel 316 and 316L EFW Pipes Manufacturer, Supplier and Exporter in Chennai, India

Based in Chennai, India, Vipul Pipes and Tubes is a reputable producer and supplier of 316L and 316 stainless steel EFW (Electric Fusion Welded) pipes, made to satisfy the requirements of demanding applications in a range of industries. Because of its high molybdenum content, SS 316 provides exceptional corrosion resistance, but SS 316L, the low-carbon version, improves weldability and lowers the possibility of intergranular corrosion following welding. Advanced welding technology is used in the production of our EFW pipes, guaranteeing superior strength, dimensional accuracy, and uniform weld seams. These pipes provide long-lasting, corrosion-resistant performance, making them perfect for high-temperature, chemical, pharmaceutical, and marine service environments.

The austenitic stainless steels 316 and 316L EFW pipes are made of molybdenum (2–3%), nickel (10–14%), and chromium (16–18%). Because of its lower carbon content (maximum 0.03%), SS 316L is more resistant to sensitization when welding. These pipes have good ductility and elongation (~40%), as well as a tensile strength of about 515 MPa and a yield strength of about 205 MPa. These pipes are appropriate for pressure systems, structural use, and harsh chemical environments because the Electric Fusion Welding (EFW) process guarantees constant strength, smooth internal surfaces, and integrity in large-diameter applications.

316 and 316L EFW pipes made of stainless steel are widely used in industries that need to withstand high temperatures, pressure, and corrosion. Chemical processing equipment, oil and gas transportation, food and beverage lines, pulp and paper industries, offshore and marine piping systems, and pharmaceutical process systems are examples of typical applications. Condensers, heat exchangers, and fluid transfer systems subjected to acidic or saline environments can also use these pipes. For welded assemblies in corrosive environments, SS 316L is particularly recommended. They are perfect for demanding and long-lasting industrial operations because of their robustness, hygienic finish, and strong resistance to corrosion caused by chloride.
