Rithav Pipes and Tubes, Delhi, India, is a reliable contractor and supplier that specializes in providing top-quality pipe solutions for industrial purposes. We are well versed in Stainless Steel 317 and 317L EFW (Electric Fusion Welded) Pipes, which are famous for their superior corrosion resistance, mechanical properties, and longevity. These pipes are produced in accordance with high-quality standards, which makes them ideal for rigorous applications in power generation, chemical processing, and oil & gas industries. With emphasis on cost-effectiveness as well as dependability, Rithav ensures that every product gives long-term performance even in most toughest conditions.
Stainless Steel 317 and 317L EFW Pipes are essentially iron-based and alloyed with 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. 317L grade contains less carbon, which increases weldability and minimizes carbide precipitation. These tubes possess high tensile strength, ductility, and pitting, crevice corrosion, and stress corrosion cracking resistance, especially in chloride environments. Their strong mechanical performance and corrosion-resistant nature make them suitable for heavy-duty and welded operations where longevity, reliability, and clean weld connections are crucial.
