MCFS Insulation Gasket Specifications

MCFS (MCG Fire Safe) insulating gasket is API 6FB certified, which includes a PTFE spring-energized primary sealing element and a Mica secondary sealing element. It adds fire service capability to the standard MCG design through the use of a secondary sealing
element of high temperature resistant Mica, which can maintain a sealing performance while subject to a fire of 1500°F (815°C). Under this design, the PTFE spring-energized primary sealing element and Mica secondary sealing element are both seated in the retainer of insulating laminate bonded to a stainless steel core, creating a fireproof insulating gasket.
Both seals of MCFS gasket have very good spring back, they require low bolt stress for the sealing. Second seal will be a backup seal under the normal environment, and it will work once the first seal failure during the fire.


MCFS Gasket Characteristics and Advantages:

1. Has Passed API 6FB FIRE SAFE test.

2. Extremely high reliability sealing and insulating solution for all critical services.
3. Seals and insulates at all pressures up to ANSI

2500# and API 10000#.

4. Unique stainless steel core bonded with high strength insulating laminate withstands severe service conditions including large bending moments, vibration, temperature and pressure cycling.
5. Designed to withstand corrosive environments, including high concentrations of CO2, H2S, produced water, etc
