FLAME ARRESTER ARRANGEMENT AND METHOD OF INCORPORATING BORES IN A FLAME ARRESTER ARRANGEMENT

摘要

pA boring (6) insertion method requires total axial closure of the coiled flame trap arrangement (1), which consists of two coiled metal strips or bands with a circular outer periphery. Total closure on both sides is achieved with retention plates (5), and from the outer periphery the boring is inserted radially inwards with a spark erosion electrode (7) under the effect of a coolant liquid. An independent claim is included for a flame-trap consisting of two coiled metal plates formed, in common, into a disc with circular outer periphery./p[EP1864695A1]
