Flame arrestor apparatus

摘要

An apparatus for extinguishing a deflagration or detonation flame travelling along a pipe includes a housing with an inlet and an outlet and couplings for connecting the inlet and outlet to the pipe. A flame extinguishing device is secured in the housing and has a plurality of serially arranged elements, each element having a plurality of longitudinally extending channels. A turbulence device is positioned between adjacent elements and has surfaces for inducing turbulence in the flame flow through the element. The housing seals the elements in a manner to direct flame flow solely through the elements and the turbulence inducing devices.
