VENT-LINE / IN-LINE
CRIMPED METAL FLAME ARRESTER
Series No. 30000
The Protectoseal Series No. 30000 Vent-Line / In-Line Crimped Metal Flame
Arrester is designed to be installed in open vent pipes from storage or
processing tanks. The arresters are used to prevent the propagation of
an external flame source through the vent opening and into the tank.
They provide maximum air-flow consistent with vapor mixtures such as gasoline
and methane (referenced as Group D atmospheres in the National Electric
Code, NEC Article 500, generally equivalent to International Electrotechnical
Commission, IEC, Group IIA.)
 The
Series 30000 utilizes wound, crimped 316 Stainless Steel foil strips to
form a heat transfer matrix of uniform triangular cells within the circular
element. The unitized crimped metal element provides a straight thru flow
path, low pressure drop and is less susceptible to clogging. The element
is mounted between arrester housings that connect to the pipe flanges.
The arrester elements are removable and interchangeable to facilitate
inspection and maintenance. A clean element may be inserted during inspection
to insure positive flame protection at all times.
When properly mounted in an open pipe line, the Series 30000 Flame Arrester
allows vapors to discharge into the atmosphere and allows air to be drawn
into the pipe through the flame arrester element assembly. These arresters
may be mounted within 20' of the end of the open vent pipe in either the
vertical or horizontal position. Flange connection provided on the 6"
through 12" sizes.
