Ojas Pipes and Tubes stands out as a top-notch manufacturer and supplier of Nickel Alloy Welded Pipes right in Kolkata, India. We specialize in delivering high-quality piping solutions tailored for industries that face tough and corrosive conditions. Our range of welded pipes comes in various nickel alloy grades, including Nickel 200/201, Alloy 400, Alloy 600, Alloy 625, and Alloy 825, all crafted to meet rigorous international standards like ASTM B517, B619, and B705. These pipes are designed to provide outstanding corrosion resistance, impressive strength, and thermal stability. At Ojas, we prioritize precision fabrication, weld integrity, and timely delivery, catering to essential sectors such as chemical processing, marine, aerospace, power, and oil & gas.
Nickel Alloy Welded Pipes are crafted from high-performance alloys that contain at least 65% Nickel, with varying amounts of Chromium, Molybdenum, Iron, Copper, and Titanium, depending on the specific grade. For instance, Alloy 625 is composed of approximately 58% Ni, 20-23% Cr, and 8-10% Mo. These pipes showcase tensile strengths ranging from 500 to 950 MPa, yield strengths between 200 and 600 MPa, and can elongate up to 45%. Thanks to advanced welding techniques, they maintain excellent resistance to corrosion and oxidation, particularly in acidic and high-temperature settings, while also offering great formability and weldability for various industrial uses.
