Detonation-fired pipe flame arresters are safety devices used to prevent the flame from flammable gases and flammable liquid vapors from spreading outward. When designing the fire retardant inner part, the regular packing is designed according to the medium of different mixed gases, the composition of the gas, the pressure drop, the aspect ratio, and the number of elbows to design the MESG value and reach a certain flame retarding speed value.
Detonation-fired pipe flame arrester Model: GZW-1
Detonation-fired pipe flame arresters are safety devices used to prevent the flame from flammable gases and flammable liquid vapors from spreading outward. When designing the fire retardant, it is based on the medium and gas of different mixed gases.
The fractional, pressure drop, aspect ratio, and number of elbows are used to design the MESG value and achieve a certain rate of fire resistance. When the flame enters the flame arrester, it is cut into many small pieces by regular flame arresting elements.
The flame flow, due to the heat transfer effect and the wall effect, the incoming gas is cooled, so that the cooled gas does not reach the ignition temperature, and the combustion cannot be formed without the ignition temperature, and finally the flame flow is extinguished.
Thereby achieving the purpose of fire prevention.

The installation and maintenance of the detonation-fired pipeline flame arrester are as follows:
1. Pipeline flame arrester should pay attention to rain, moisture and oil in the process of transportation and storage.
2. The pipe or accessory flange gasket connected to the pipe flame arrester shall be annealed and softened aluminum, copper or copper wire.
3. In order to prevent fire, before and after the oxygen pipeline flame arrester with working pressure greater than 0.6MPa, a copper-based alloy (or stainless steel "target=_blank> stainless steel) pipe should be connected, the length is not less than 5 pipe diameter, and not less than 1.5m. ,
It is not allowed to install all fittings.
4. After the pipeline flame arrester is installed on the pipeline, the system strength and leakage test shall be carried out according to the system design rules, and special cleaning shall be carried out.
5. After the pipeline flame arrester is deactivated for a long time, it should be thoroughly cleaned again when it is used again.
