Liam Pipes & Tubes provides premium quality Monel Tubing from Houston, USA, in seamless and welded conditions. Fabricated from Monel 400 and K500 alloys, the tubing is suitable for saltwater, acid, and high-temperature applications. Renowned for great corrosion resistance and mechanical strength, Monel tubing conforms to ASTM B165, B730, and B725 specifications. It possesses better weldability, thermal conductivity, and pressure bearing strengths. Monel tubing is relied upon for long-term applications in marine, chemical processing, oil and gas, and aerospace industries where materials are required to bear stringent, corrosive, or high-stress applications.
Monel tubing consists of ~63% nickel, ~30% copper, and trace iron, manganese, and silicon. Monel K500 contains aluminum and titanium for age hardening. It has tensile strengths from 480 MPa (Monel 400) to 770 MPa (Monel K500), with good ductility and corrosion resistance. The tubing comes in annealed or cold-drawn finishes, with tight tolerances and smooth internal surfaces. It operates exceptionally well in oxidizing and reducing conditions. Monel tubing retains mechanical integrity and leak-tight sealing capabilities in high-pressure, high-heat, and corrosive environments.
