Flame Arresters

Flame Arresters

A Flame Arrester is a device which allows gas to pass through it but extinguishes a flame in order to prevent a larger fire or explosion. We offer numerous flame arresters which can be applied for different situations

Motherwell’s vent combination arresters offer protection for end-of-line applications, preventing unconfined ignition. Certified to ATEX standards, suitable for pipe sizes from 2″ to 12″, bi-directional.

APPLICATION

Our Flame arrestors are designed to be used in the bulk liquid storage industry either end of line or in conjunction with a PVRV unit and installed at the end of a pipeline or exit vent on a vessel. They allow for an unrestricted flow of gases into the atmosphere and clean air into the tank/pipe therefore preventing any possible atmospheric deflagration from entering the system.

 

PRINCIPLE OF OPERATION

A Vent Combination unit is designed to be mounted with a PVRV and prevent an unconfined deflagration in the surrounding atmosphere from entering the pipe or system and is not suitable for preventing a flame from within the pipe or system igniting the surrounding area.
