197 EN P END OF LINE DEFLAGRATION FLAME ARRESTERS AND PRESSURE VACUUM VENTS 197 EN P IS AN END OF LINE FLAME ARRESTER COMBINED WITH A PRESSURE VACUUM VENT. ALLOWING THREE DIFFERENT FUNCTIONS IN ONE DEVICE. It prevents flame spread by absorbing and dissipating heat by means of a ribbon coliled element made of stainless steel. The standard application consists in preventing fire flames transmission to a confined area. An underground storage tank in a gas station forecourt might be the classic example. When an accidental ignition of a flammable mixture may results in a firefront, end of line flame arrester will avoid the flame transmission to the pipework system. Their main function is definetely to protect people, plants and environment. Further more the pressure/vacuum function protect the integrity of the tank in the daily use enabling business continuity.

RIBBON COILS WHAT IS A FLAME ARRESTER ? Flame arresters are passive mechanical devices designed to allow the passage of gasses and to prevent flame transmission. Many factors influence the bursting event like the chemical composition of the mixture, pressure waves pre-compression, or flame propagation speed. Thanks to technology, flame arresters can be applied in various situations to stop the flame and prevent large fire breakouts.

FUNCTIONING, INSTALLATION AND FEATURES PRESSURE VACUUM VENT FUNCTION Pressure Vacuum Vents are installed on the top of vent pipes from underground or above ground fuel storage tanks. A normally closed poppet in the valve opens at a predetermined pressure or vacuum setting to allow the tank to breath.

RSION DISPE One of the greatest dangers involved with the transport or storage of flammable liquids or gases is that ignition of the flammable vapour may occur, resulting in fire or, even worse, an explosion. A flame arrester is a device fitted to the opening of an enclosure, or to the connecting pipework in a system of enclosures. They permit gases or vapours to flow under normal operating conditions but prevent the transmission of a flame should an ignition take place. Whenever a flammable gas or vapour is mixed with air (oxygen), there is the potential for an explosion. Accidental ignition...
