Ojas Pipes and Tubes stands out as a trusted manufacturer and supplier of Nickel Alloy EFW Pipes, proudly based in Kolkata, India. We specialize in delivering top-notch welded piping solutions tailored for high-performance industrial applications. Our EFW pipes come in a variety of nickel alloy grades, including Nickel 200/201, Alloy 400, Alloy 600, Alloy 625, and Alloy 825, all crafted to meet global standards like ASTM B514 and B705. Designed to excel in resisting corrosion, stress, and high temperatures, our pipes reflect our commitment to precision welding, dimensional accuracy, and mechanical integrity, making them a reliable choice for the chemical, marine, aerospace, and energy sectors.
Nickel Alloy EFW Pipes are crafted from alloys with a high Nickel content (65% and above), blended with elements like Chromium, Molybdenum, Iron, Copper, and Titanium, depending on the specific grade. For instance, Alloy 825 features approximately 42% Nickel, 19–23% Chromium, and 2.5–3.5% Molybdenum. These pipes boast impressive tensile strength ranging from 500 to 950 MPa, yield strength between 200 and 600 MPa, and elongation rates of 30–45%. EFW pipes are engineered for exceptional corrosion resistance, weld integrity, and thermal stability, making them perfect for demanding operational conditions that involve aggressive media and high pressure or temperature.
