Liam Pipes and Tubes is a reliable manufacturer and supplier of Invar 36 Pipes, proudly based in Houston, USA. They specialize in precision-engineered nickel-iron alloy piping solutions that are perfect for applications where minimal thermal expansion and high dimensional stability are essential. Known as Alloy 36 or UNS K93600, Invar 36 is a go-to choice in industries that demand strict temperature-sensitive dimensional control. Liam Pipes and Tubes offers Invar 36 Pipes in both seamless and welded forms, with customizable diameters, wall thicknesses, and lengths tailored to meet specific project needs. Their top-notch pipes are crafted in accordance with international standards, making them ideal for sectors like aerospace, cryogenics, electronics, and scientific instrumentation.
Invar 36 Pipes are composed of a nickel-iron alloy that contains about 36% nickel and 64% iron. This special blend results in an incredibly low coefficient of thermal expansion (CTE) — typically around 1.2 × 10⁻⁶/°C between -100°C and 200°C — which is why it’s so well-suited for temperature-sensitive applications. The alloy boasts a tensile strength ranging from 485 to 620 MPa and a yield strength of about 275 MPa, along with good ductility and toughness. It also offers excellent dimensional stability, moderate corrosion resistance, and is easy to machine and weld under controlled conditions.
