Explosion Proof Flame Arrestor Vent Cage

The explosion proof flame arrestor vent cage usually used together with the flame arrestors, breather valves, it is a very important part for the pipeline safety system.

We are the professional manufacturer for all kinds of the storage tank and pipe line fittings, such as the flame arrester, breather valve, filters...... which are suitable for flammable gas storage tank or transport pipeline.

Our products follow the ISO16852 standards for testing and manufacturing, CE certification. Through the national special equipment inspection and Research Institute of the full type test, resistance to fire performance is excellent, to obtain TSG certification.

We have already produced the maximum diameter of the pipe flame arrester 24 inch, product performance was widely recognized petrochemical enterprises. And our products were exported to all over the world.

The explosion proof flame arrestor vent cage was specifically developed for vessels which are not pressurized and store Ethanol or other alcohols. The combustion of alcohol requires a modified flame arrester element design to provide protection against endurance burning. In addition, the device provides protection against atmospheric deflagration. Main application area is on suction and vent lines, for inland navigation vessels and on shore systems with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration.

The explosion proof flame arrestor vent cage consists of a housing (1), a weather hood (2) and the flame arrester unit (3). During normal operation the metal weather hood is in a closed position. If a stabilized flame burns on the flame arrester element surface, the fusible link (5), located in a center position, will melt and let the spring loaded weather hood move into the open position. The flame arrester unit consists of two discs (4), which are installed in a casing.

The explosion proof flame arrestor vent cage is available for hydrocarbons for explosion group IIB3 (MESG ≥ 0,65 mm) and alcohols.

The standard design can be used for operating temperatures up to +60°C / 140°F.

EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.


Flame Arrester Valve Testing Standard
Test Conditions
Unless otherwise specified, the tests outlined in this chapter should be conducted under normal atmospheric conditions, which are defined as follows:

a) Ambient temperature: 15°C to 35°C;

b) Relative humidity: 45% to 75%;

c) Atmospheric pressure: 86 kPa to 106 kPa.
 

Parallel plate element design provides significant mechanical strength while minimizing pressure drop
Weatherhood protects against environmental conditions
Automatic condensate drainage mitigates freezing and clogging

The explosion proof flame arrestor vent cage is used for urban industrial and mining enterprises ,gas stations ,and it's an important accessory .usually use at below conditions:
(1) transport inflammable gas and flammable gas pipeline
(2) storage petroleum and petroleum product tank
(3) with explosion insecure system vent-pipe
(4) oil and gas recycling system
(5) regenerative boiler burning gas pileline net
(6) gas engine exhaust system
(7) torch system
