ABSTRACT:
Suppression apparatus for suppressing detonations in a pipeline which may contain an explosible vapor comprising suppressant discharge units for discharging a suppressant substance into the pipeline within a predetermined operating time. Detectors are positioned upstream of the suppressor means by sufficient distance in relation to the expected speed of travel of the detonation front along the pipeline, and in relation to the predetermined operating time of the suppressant discharge units, that the pipeline in the region of the discharge units will be supplied with an amount of suppressant which is sufficient to ensure that the detonation is suppressed when it reaches the discharge units. The suppressant may be a powder or water. Mechanical arresting means may also be provided such as a valve for positively blocking the pipeline in the event of the detection of a detonation, and/or the pipeline may have a membrane which is ruptured by the detonation so as to vent it to atmosphere.
