Incoloy Flanges

Incoloy flanges specfication

What are incoloy flanges?

These flanges comprise nickel, chromium, iron, molybdenum, copper, and titanium to create leak-tight seals in industrial applications. Incoloy flanges have a reputation for excellent corrosion and oxidation resistance. Clients can procure them in different grades, for instance, incoloy 825 flanges and 800.

What are the uses and applications of incoloy 800 and 825 flanges?

These components operate in numerous core industries, including chemical processing, oil and gas, and pollution control. Incoloy 800 flange have applications in power plants (fossil fuel and nuclear power), municipal piping, and food processing. Alloy 825 flanges are useful for pickling operations, waste handling (radioactive), and heat exchangers.

We are committed to providing innovative solutions through the supply of superior quality inconel 825 flanges, check how does Incoloy alloy 825 slip on flange perform in high-temperature and corrosive environments

How do incoloy 800h/800ht flanges perform in high-temperature and corrosive environments?

These this material displays satisfying performance in corrosive conditions and elevated temperatures. An inconel 800ht flanges can withstand stress cracking and crevice corrosion in chloride environments. Products can operate under cryogenic temperatures up to over 1000°f. 800h and 800ht display superior strength against creep and rupture under high temperatures. An incoloy 800 forged ring often works in sheathing and tubing for steam generators.

Our Werkstoff 2.4858 weld neck flange are vital for industries needing high-performance solutions in tough environments, view benefits of using incoloy 800 ht plate flanges with us

What are the key benefits of using an incoloy slip on flange?

Slip on flanges are not complex, save space, and provide good sealing performance. An incoloy alloy 825 slip on flanges has a high amount of nickel, molybdenum, and copper. It also contains titanium. This composition lends protection against intergranular and general corrosion. Another benefit is high fabricability and weldability.
