Rithav Pipes and Tubes stands out as a trusted manufacturer and supplier of Stainless Steel 304L EFW Pipes right here in Delhi, India. We pride ourselves on delivering top-notch welded piping solutions that cater to a variety of industries. The SS 304L variant is a low-carbon form of 304 stainless steel, known for its exceptional corrosion resistance and impressive weldability, particularly in high-temperature or corrosive settings. Our Electric Fusion Welded (EFW) pipes are crafted to meet ASTM A312 and A358 standards, guaranteeing precise dimensions, robust welds, and outstanding durability. Rithav’s 304L EFW pipes are perfect for applications in chemical processing, food industries, water treatment systems, and structural piping projects.
Stainless Steel 304L EFW Pipes are made up of Chromium (18–20%) and Nickel (8–12%), with a low Carbon content (≤0.035%), which gives them remarkable resistance to intergranular corrosion, especially post-welding. They also contain controlled amounts of Manganese, Silicon, Phosphorus, and Sulfur. These pipes boast a minimum tensile strength of 70,000 psi and a yield strength of 25,000 psi. Following ASTM A312/A358 standards, Rithav Pipes and Tubes ensures that every pipe undergoes rigorous testing for mechanical strength, weld integrity, and chemical composition, delivering reliable and consistent performance.
