Generally divided into two categories:
One type is a flame arrester for large hydrogen pipes. This flame arrester is flanged. According to the inner diameter of the pipe, the specifications are: DN15, DN20, DN25, DN40, DN50, DN80, DN100, DN150, DN200, DN250 and so on.
The second category is a flame arrester for hydrogen bottles. There are generally three types:
The first type is connected to a hydrogen cylinder (one end is thread M16*1.5, one end is Φ8 or Φ10 leather joint);
The second type is threaded at both ends (M16*1.5); hydrogen bottle flame arrester
The third type is a leather joint at both ends (Φ8 or Φ10)
Flame arresters are classified into three types: explosion-proof, burn-resistant and shock-proof. Flame arresters installed in series with the mechanical breathing valve at the top of the tank are usually explosion proof.
