The core of the flame arrester is made of stainless steel, which is corrosion resistant and easy to clean.

Acetylene flame arresters are suitable for pipelines with flash points lower than 28 C Class A, oils, oxyhydrogen liquefaction and flash points lower than 60 C.

The flame arrester is used on the gas pipeline of the heating furnace. It should be installed on the fuel oxygen pipeline where oxygen is entered into the nozzle to prevent fire.
