OCECO Types "P" and "PF" Flame Retarders have been used for many years in process gas lines to minimize the hazard of "flash-back". They are usually installed as near the outlet as possible and employ a retarding element designed to check an ignition of the downstream gas at the element assembly.
The element consists of corrugated and flat metal sheets rolled into a tight cylinder, which is then inserted in a steel housing. The rolled sheets are held tightly against the inside walls of the housing by tapered plugs forced into the center of the cylinder at each end.
Both flame retarder models are designed in such a manner that the center body section may be removed for inspection of the element assembly without disturbing the piping.
Flame Retarders for use in applications requiring higher pressures or non-standard materials of construction are available on special order.
