Incoloy 800/H/HT Flanges Manufacturer, Incoloy 800/H/HT Flanges, Incoloy 800/H/HT Flanges in India, Incoloy 800/H/HT Flanges in Mumbai
Incoloy 800/H/HT Flanges are premium-grade, corrosion-resistant components designed for high-temperature and high-pressure applications. Made from nickel-iron-chromium alloys, these flanges are known for their excellent mechanical strength and outstanding resistance to oxidation, carburization, and chloride stress corrosion cracking. Labdhi Metals, a leading manufacturer, stockist, and exporter, offers a comprehensive range of Incoloy 800, 800H, and 800HT flanges that conform to international standards and industrial specifications.
Incoloy 800 Flanges serve well in moderate high-temperature applications, while the 800H and 800HT variants offer enhanced mechanical strength due to controlled carbon and increased aluminum and titanium content. These flanges maintain structural stability even under prolonged exposure to temperatures up to 1100°C, making them ideal for applications in heat exchangers, pressure vessels, power plants, and furnace equipment. Labdhi Metals ensures each flange is precision-machined and tested to meet strict dimensional and metallurgical standards.
The product range includes Slip-On Flanges, Weld Neck Flanges, Blind Flanges, Socket Weld Flanges, Lap Joint Flanges, and Threaded Flanges, available in various pressure classes such as 150#, 300#, 600#, and above. Labdhi Metals provides Incoloy 800/H/HT Flanges in sizes ranging from ½” NB to 24” NB, and custom solutions are available to meet unique project requirements. Each flange is subjected to quality assurance checks including PMI (Positive Material Identification), hydro testing, and radiographic testing to ensure top performance and durability.
These flanges are particularly important in applications involving high-temperature steam, sulfur-rich environments, and corrosive media, especially in petrochemical and power industries. Incoloy 800/H/HT Flanges offer excellent weldability and long service life, reducing maintenance costs and downtime. Labdhi Metals also provides technical consultation and third-party inspection (TPI) certifications on request.
