Ojas Pipes and Tubes stands out as a leading manufacturer and supplier of Nickel Alloy ERW (Electric Resistance Welded) Pipes based in Kolkata, India. We pride ourselves on delivering top-notch piping solutions tailored for high-performance industrial applications. Our nickel alloy ERW pipes are designed with exceptional corrosion resistance, impressive strength, and long-lasting durability, all crafted to meet rigorous international standards like ASTM B163 and ASTM B165. Each pipe is meticulously welded to ensure precise dimensional accuracy and mechanical integrity, making them perfect for critical applications in chemical processing, power generation, marine engineering, and aerospace industries. At Ojas, we guarantee reliability and a long service life for all your nickel alloy piping needs.
Nickel Alloy ERW Pipes are primarily made up of a high Nickel content (≥65%) along with alloying elements such as Chromium, Molybdenum, Iron, and Copper, depending on the specific grade (like Alloy 400, 625, or 825). These alloys are known for their outstanding resistance to oxidation, corrosion, and high temperatures. In terms of mechanical properties, they boast tensile strength ranging from 450 to 950 MPa, yield strength between 200 and 690 MPa, and elongation values of 30–45%. The ERW welding process guarantees uniform welds with high structural integrity, making them suitable for pressure and high-temperature applications.
