Buy Top Quality ASTM B564 Incoloy 800 Threaded Flange and Alloy 800H/HT Lap Joint Flange at Best Prices.

Creative Piping is a trusted manufacturer and supplier of high-quality Incoloy 800 flanges. Incoloy 800 flanges are components manufactured from this alloy, designed specifically for connecting sections of piping systems in environments where elevated temperatures and corrosive substances are present. At Creative Piping, we prioritize excellence in both product quality and customer service, delivering reliable solutions for your piping needs.

Incoloy 800 flanges retain their mechanical properties at elevated temperatures, making them suitable for applications where standard materials would weaken or fail. Incoloy 800 flanges are generally weldable using conventional welding techniques. Proper welding procedures and precautions must be followed to maintain the integrity of the weld and the overall performance of the flange.

01 What is Incoloy 800?

Incoloy 800 is a nickel-iron-chromium alloy with excellent strength and resistance to oxidation, carburization, and corrosion at high temperatures. It is commonly used in applications requiring materials to withstand extreme environments.

Incoloy 800 flanges are used to connect sections of piping systems in environments where high temperatures and corrosive substances are present. They provide a reliable and durable connection that maintains the integrity of the piping system.

Incoloy 800 flanges exhibit high-temperature strength, excellent corrosion resistance, and resistance to carburization. They also offer good mechanical properties, including high tensile and yield strength, ductility, and toughness.
