These pipes are celebrated for their exceptional strength, resistance to corrosion, and precise dimensional accuracy. Crafted from high-quality stainless steel and utilizing cutting-edge welding techniques, our EFW pipes deliver seamless performance even in high-pressure and corrosive settings. Available in various grades like 304, 316, and 310, they meet international standards for industrial reliability. Aditya Stainless caters to industries such as oil & gas, petrochemicals, power generation, and water treatment, providing robust and efficient piping solutions designed for demanding applications.
Stainless Steel EFW Pipes are mainly offered in grades such as 304, 316, and 310. Their typical composition features chromium (18–25%), nickel (8–20%), and molybdenum (2–3% in 316), which contribute to their outstanding corrosion resistance and strength. These pipes boast a tensile strength ranging from 500–750 MPa and a yield strength of about 200–350 MPa, with elongation reaching up to 40%. EFW pipes are known for their excellent weldability, high-temperature resistance, and ability to handle pressure. The smooth internal finish minimizes flow resistance, while their mechanical integrity and metallurgical stability make them perfect for both corrosive and high-temperature applications.
