Liam Pipes and Tubes is a reputable manufacturer and supplier based in Houston, USA, specializing in Incoloy 800, 800H, and 800HT Tubing. They offer top-notch nickel-iron-chromium alloy tubing solutions that are engineered to excel in high-temperature environments, providing strength, oxidation resistance, and structural stability. Each of these tubing grades is a unique variation of the Incoloy 800 series, crafted to endure prolonged exposure to elevated temperatures without compromising their strength or becoming brittle. Liam Pipes and Tubes supplies both seamless and welded tubing in a variety of sizes, thicknesses, and lengths, all in line with international standards like ASTM B407 and ASME SB407, making them perfect for applications in petrochemical, power generation, and furnace settings.
The Incoloy 800/800H/800HT Tubing is primarily made up of nickel (30–35%), chromium (19–23%), and iron (the balance), with slight variations in carbon, aluminum, and titanium across the three grades. Incoloy 800 serves as the standard grade, offering solid strength and oxidation resistance. The 800H variant has a higher carbon content (0.05–0.10%) to enhance creep and rupture strength, while the 800HT grade includes controlled amounts of aluminum (0.25–0.60%) and titanium (0.25–0.60%) for improved performance at high temperatures. These alloys boast impressive tensile strength (up to 600 MPa) and maintain their structural integrity at temperatures reaching 1100°C (2000°F).
