Home > Invar 36 Pipe
Bulan Pipes and Tubes, a reputable manufacturer and supplier located in Jakarta, Indonesia, specializes in high-quality Invar 36 Pipes, designed for applications where precision is key. Invar 36 is a nickel-iron alloy celebrated for its remarkably low thermal expansion coefficient, making it perfect for settings that require dimensional stability even with temperature changes. Our Invar 36 pipes are crafted in line with international standards like ASTM F1684, ensuring exceptional machinability, thermal resistance, and tight tolerances. We proudly serve high-tech sectors such as aerospace, cryogenics, electronics, and scientific instrumentation, providing reliable, high-performance alloy piping solutions built to withstand extreme conditions.
Invar 36 Pipe consists of about 36% nickel and 64% iron, along with small amounts of carbon, manganese, and silicon. This distinctive blend results in an incredibly low thermal expansion coefficient (~1.2 × 10⁻⁶/°C) across a temperature range of −100°C to 200°C. In terms of mechanical properties, it boasts a tensile strength of 485–620 MPa, a yield strength of around 275 MPa, and an elongation of 30–45%. Invar 36 also offers excellent dimensional stability, moderate resistance to corrosion, and good machinability, making it essential for applications where minimizing temperature-induced expansion is crucial.
