Flame Arresters, Detonation Arresters and Flame ScreensFlame Arresters Detonation Arresters and Flame Screens

Venting systems are used on marine vessels to balance pressure differences between the cargo tank and the surroundings.

Mixtures of flammable cargo vapour and air are expelled during loading and unloading, and vent systems prevent flames from entering the piping system and the cargo tank. This is called Flashback and it happens if the system is accidentally exposed to a spark or ignition. It can result in an explosion. In the worst case, this can lead to loss of life and less importantly, substantial equipment losses.

International and national standards for flame arresters are rapidly evolving. At Pres Vac Engineering we carefully monitor development in this area to ensure compliance with current and expected regulations.
