Maria Pipes and Tubes, a top-notch manufacturer and supplier based in Kuala Lumpur, Malaysia, specializes in high-quality Incoloy 800/800H/800HT Tubing, crafted for outstanding performance in extreme temperatures and corrosive settings. These tubes are made to comply with international quality standards, ensuring they provide remarkable strength, oxidation resistance, and structural stability. The 800 series comes in different variants to meet specific performance requirements: Incoloy 800 is designed for general high-temperature corrosion resistance, 800H offers enhanced creep strength, and 800HT is optimized for superior structural stability at elevated temperatures. Catering to sectors like petrochemical, power generation, chemical processing, and heat treatment, Maria Pipes and Tubes guarantees reliable, long-lasting tubing solutions.
Incoloy 800/800H/800HT Tubing primarily consists of nickel (30–35%), chromium (19–23%), and iron, with carefully controlled levels of carbon, aluminum, and titanium. This unique blend provides exceptional resistance to oxidation, carburization, and corrosion in high-temperature applications. In terms of mechanical properties, 800 delivers solid strength and corrosion resistance, 800H boasts higher creep rupture strength thanks to its increased carbon content, and 800HT offers enhanced stability through optimized levels of aluminum and titanium. All three variants maintain impressive structural integrity even under prolonged exposure to heat.
