APPENDIX
A
Flame Arrester Specification Sheet
for Manufacturer Quotation
To enable flame arrester manufacturers to select and provide the correct
flame arrester for a specific application, they must be given all relevant
data pertaining to the proposed installation. These data are usually trans-
mitted to manufacturers by means of a flame arrester specification (data)
sheet. When in-line detonation flame arresters are to be installed in a
vented manifold (vapor collection) system, it is imperative that a system
sketch (or piping isometric drawing) be included with the specification
sheet to show all horizontal and vertical piping runs (with dimensions) and
all fittings (elbows, tees, valves, etc.). These are needed to estimate the
potential for DDT and to determine where all detonation arresters must be
located in the piping. Also, if the gashapor stream is a multicomponent
mixture, a complete definition of the stream composition, including minor
corrosive or fouling components, should be appended to the data sheet.
The MESG, NEC group, and AIT for each component should be listed as
well.
Printed on the next page is a flame arrester specification (data) sheet
that is a composite of data sheets from several flame arrester manufactur-
ers and CPI companies. Most flame arrester manufacturers have their own
data sheets, which can be used with additional data added as the user
deems necessary.
