Advantages

Overview of Incoloy Gaskets

Not to be confused with Inconel, Incoloy gaskets are made of a nickel alloy which contains iron and a lower content of nickel. Incoloy is essentially a more economical option to Inconel, yet with more restricted corrosion resistance and temperature limits. Typically, Incoloy is an ideal material for long-term exposure in high temperature environments due to its oxidation, carburization and creep resistance. Incoloy is widely used for its resistance to seawater, brine, sour gas and high chloride environments at elevated temperatures, which make it a popular choice in the oil and gas and power industries. 

Incoloy semi-metalic gaskets with a PTFE or graphite soft sealing material are available in the Revoseal JG / JP design which is usable in the most corrosive environments and has a pressure rating of from vacuum to 5800psi / 400bar. With a leak rate 15000x less than spiral wound gaskets, you can be sure that hazardous fumes and vapors will be conatained creating the safest work environment possible. Furthermore, our Incoloy gaskets are customizable and accomodate dissimilar flange faces and large gaps.

The most commonly used grades of Incoloy gaskets are Incoloy 800, 800H, 800HT; and  Incoloy 825. For more indepth information on these specific grades, visit our specific web pages or contact one of our engineering experts:
