Wind-pressure smoke detection and leakproofness testing method of air pipe and wind-pressure smoke detection testing system of air pipe

The invention discloses a wind-pressure smoke detection and leakproofness testing method of an air pipe and a wind-pressure smoke detection testing system of the air pipe. The wind-pressure smoke detection and leakproofness testing method of the air pipe comprises a smoke leakage detection method, and smoke escapes to the leaking hole position under the action of high pressure, so that the leaking hole can be conveniently and visually observed, convenience and reliability are achieved, and meanwhile, harmful effects caused by hydraulic pressuring test are prevented.
