DETONATION FLAME ARRESTER
Series No. 25000 & 26000
 The
Protectoseal Series Nos. 25000 & 26000 Detonation Flame Arresters are
specifically designed to withstand and arrest the high velocity and high
pressure flame fronts that may develop in long or complex piping runs
such as those encountered in vapor recovery or manifolded tank systems.
The arresters provide positive protection against flame transmission through
piping systems handling chemical vapor mixtures as referenced in the National
Electric Code (NEC) Article 500:
Series No. 25000 - Suitable
for use with Group D chemical vapors, generally equivalent to International
Electrotechnical Commission (IEC) Group IIA.
Series No. 26000 - Suitable
for use with Groups C & D chemical vapors, generally equivalent to International
Electrotechnical Commission (IEC) Group IIA and IIB.
When properly specified and installed, the Series 25000 and 26000 Detonation
Arresters are designed to stop unconfined deflagrations, low speed, low
pressure confined deflagrations, high speed, high pressure confined deflagrations
and both stable and overdriven detonations. A stable detonation is defined
as "the movement of a flame through a gas or vapor at a velocity equal
to the speed of sound in the burnt vapor". An overdriven detonation is
characterized by flame speeds and pressures greater than those of a stable
detonation. The proven ability to withstand this variety of flame fronts
is a key characteristic of a detonation flame arrester. The arresters
are bidirectional, able to stop a flame approaching from either direction
in the piping system.
The Series 25000 & 26000 utilize wound crimped 316 Stainless Steel foil
strips to form a heat transfer matrix of uniform triangular cells within
the circular element. The size and shape of the openings in the crimped
metal element and the length of passage through these openings have been
designed to insure the ability of the device to quench multiple detonations
and deflagrations. The crimped metal arrester design allows for flexibility
in application. The ability to control the size of the openings is the
key to arresting a variety of flame fronts. The one-piece, unitized arrester
elements are easily removable and interchangeable. This permits a clean
spare arrester to be inserted for positive protection at all times. All
standard units flanged to mate with 150# RF ANSI flange connections.
Protectoseal Detonation Flame Arresters have been thoroughly tested and
certified as being effective by the most respected independent laboratories
and approval agencies in the world. Underwriters' Laboratories (UL), Underwriters'
Laboratories of Canada (ULC), Factory Mutual Research (FM) and United
States Coast Guard (USCG) have all granted approvals and acceptances to
Protectoseal detonation arresters.
