SECTION III
III. TRANSPORTATION AND STORAGE
The flame arrestor shall be packed carefully in order to prevent damages or impurity during the transport
or storage.
SECTION IV
IV. INSTALLATION AND ASSEMBLY
Basically, the installation and assembly of the flame arrestor is carried out considering the respective application
limits and regulations for the scope, especially the appropriate instruction for accident prevention by the customer.
The installation starts by removing the plug connection/flange cover at the inlet and outlet of the flame arrestor.
The threads respectively and facing of the flanges shall be checked for damages, foreign material or dirt. The
flame arrestor may be installed horizontally or vertically . A tensionless fitting shall be guaranteed. Additionally, the
flame arrestor is not to be used as a load bearing device. If the flame arrestor is marked with a sticker "Protected
side", this side has to be installed opposing the potential ignition source. With bidirectional flame arrestors, position
consideration of the potential ignition source is not required.
For inline flame arrestors the pipe size on the protected side shall not be smaller than the pipe size on the unprotected
side. For inline flame arrestors the pipe size on the unprotected side shall not be bigger than the connection size of
the flame arrestor. The distance (L
) between the potential ignition source and the deflagration inline flame arrestor
U
shall not exceed the data given in the Charts 1-3.
If the flame arrestor is marked as "Protected against endurance burning" (BC: a), it must not be insulated or encased.
With a marking "Protected against short burning" (BC: b) at least one screw plug including the used seal ring has to
be removed after assembling the flame arrestor. It shall be replaced by the included resistance thermometer (PT100)
+ seal ring. If stabilized burning is possible on both sides, at least one temperature sensing device shall be installed
on each side. The installation guidelines by the manufacturer of the resistance thermometer and requirements of
compliance shall be fulfilled. Then the installed temperature sensing device or devices will have to be integrated into
the complete system in order to activate an emergency function. The circuit must permit a clearing of the ominous
state within 50% of the burn time stated on the warning sign. Other brans of resistance thermometers may be used
if their measurement features are identical with the measurement features of the resistance thermometers used in
testing, and if the electrical explosion protection meets the respective application conditions of the flame arrestor.
In order to guarantee that no gap to the atmosphere has developed a leakage test should be carried out
before initial operation. Attention! Do Not exceed the test pressures stated in the inspection certificate
(EN10204).
