Piping detonation arrestors

Pipe detonation arrestors are provided where there is a possibility of highly accelerating flame fronts within piping systems due to poor piping designs to prevent such occurrences.

In the past it was difficult to prevent the spread of explosions through vent systems, as flame arrestors were effective only when located at the ends of pipes. Effective inline detonation arrestors are now availabe. Like all flame arrestors they will, of course, need regular cleaning, something that is often neglected. In other cases, when tanks have been over-... 

Flame or detonation arrestors If properly designed, installed, and maintained, can eliminate the potential for flashback through a piping system or into a vessel or tank 1 x 101 to 1 X 10 3 1 x 10 2... 

A special study [74] was commissioned by the American Petroleum Institute (API) entitled Mitigation of Explosion Hazards of Marine Vapor Control Systems. The report examines the effects of deflagradons and detonations in pipes in the region of detonation flame arrestors. The primary objective was to resolve potential... 

The usual approach in design is to prevent explosions from occurring, for example, by not allowing flammable mixtures to form in the process. If internal explosion is a possibility, then it must be considered as a pressure-relief scenario and the pressure-relief devices must be sized to prevent detonation. This will usually require the use of large bursting disks. Flame arrestors should also be specified on process piping to... 

Vapor cloud explosions are due to rapid combustion of flammable gas, mist, or small particles that generate pressure effects due to confinement they can occur inside process equipment or pipes, buildings, and other contained areas. A vapor cloud explosion can be either a deflagration or a detonation (the distinction between deflagrations and detonations is important when deciding on whether or not to use a flame arrestor in pressure relief systems).
