3 Terms and definitions

The following terms and definitions apply to this document.

Pipe flame arrester pipelineflamearrester Installed in the transport of combustible gas pipeline to prevent the propagation of flame (detonation or detonation) through the device, the fire core, flame arrester shell and attached Pieces constitute.

Explosion deflagration flame arrester Flame arrestor can prevent the spread of flame. Deflagration refers to the heat conduction and diffusion mode, relative to the front of the medium to spread sound at subsonic combustion Reaction form.

Detonation flame arrester Flame arrestors that prevent the spread of detonation. Detonation is based on the shock compression method, relative to the front of the medium to the supersonic propagation of combustion reaction form.

Fire-resistant flame arrester enduranceburningflamearrester Flame arrestors that prevent flame propagation during burn-resistant and burn-resistant.

Maximum test safety clearance maximumexperimentalsafetygap MESG Under standard test conditions (0.1 MPa, 20 ° C), the slit width (slit length 25 mm) just enough to prevent the flame from passing.

NOTE The definition of MESG is an internationally harmonized, standardized MESG test setup.
