FIKE Explosion Isolation
Burning material produced in the initial stages of a deflagration are conveyed through any open connections (ducts, piping, chutes, conveyors)putting connected equipment and facilities at risk to secondary explosions.These secondary explosions often cause the most devastation. Regardless of the protection measures considered, explosions must be prevented from propagating to other locations within the plant.
FikeExplosion Isolation systems prevent the propagation of flame through the use of fast-acting valves and/or chemical barriers – effectively eliminating secondary explosion.
MECHANICAL EXPLOSION ISOLATION
Involves the use of mechanical valves to provide a physical barrier, preventing.
propagation of an explosion. Depending on the application and/or protected process, Fike has several options and sizes available:
Designed to close within milliseconds of detecting an explosion, Fike’s EIVprevents the spread of flames andpressure (in both directions), preventingan explosion from propagating. Fike EIVsare one of the fastest, mosteffective formsof explosion protection available
The EIPV consists of a heavy duty cast valve body containing arugged elastomeric sleeve. Upon explosion detection,compressed air is released and within milliseconds the sleeve is“pinched” to full closure, stopping the explosion from spreadingbeyond the valve. Used in conjunction with other Fike explosionprotection components, the EIPV is an economical way toprevent deflagration propagation.
CHEMICAL EXPLOSION ISOLATION
It’s achieved through a rapid discharge of a chemicalexplosion suppressant which prevents the flame from spreadingto other areas of the process system.
An injection of a chemical extinguishing agent into the ductwork creates a barrier against flame propagation.
