Rithav Pipes and Tubes, based in Delhi, India, stands out as a trusted manufacturer and supplier of Invar 36 Pipes, specifically designed for applications that demand minimal thermal expansion and exceptional dimensional stability. Invar 36 is a nickel-iron alloy with 36% nickel, celebrated for its nearly zero coefficient of thermal expansion, making it perfect for precision instrumentation and aerospace systems. At Rithav, we offer high-purity Invar 36 seamless and welded pipes, ensuring strict quality control and compliance with international standards like ASTM F1684. Our Invar piping solutions are relied upon across high-tech industries for their reliable performance in temperature-sensitive settings.
Invar 36 Pipes consist of about 64% iron and 36% nickel, along with small amounts of carbon, manganese, silicon, and chromium. This distinctive composition results in a coefficient of thermal expansion as low as 1.2 × 10⁻⁶/°C between -100°C and 260°C. The mechanical properties include a tensile strength ranging from 450 to 650 MPa, a yield strength of around 240 MPa, and an elongation of 30 to 40%, depending on the heat treatment. Invar 36 is known for its dimensional stability across a broad temperature range, providing excellent toughness, good weldability, and moderate corrosion resistance, making it a top choice for precision applications.
