Abstract:
1. A method for containing and monitoring gas pipe leakage comprising: surrounding a first pipe fitting of a first monitored pipe with a first pipe clamp to form a first containment chamber having an inlet port and an outlet port between the first pipe fitting and the first pipe clamp; surrounding a second pipe fitting of a second monitored pipe with a second pipe clamp to form a second containment chamber an inlet port and an outlet port between the second pipe fitting and the second pipe clamp; monitoring pressure inside the first containment chamber within the first pipe clamp via a first pressure sensor; monitoring pressure inside the second containment chamber within second pipe clamp via a second pressure sensor; connecting the first containment chamber with second containment chamber in series with an exhaust line connected to the input port of the first pipe clamp and between the output port of the first pipe clamp and the input port of the second pipe clamp and the outlet port of the second pipe clamp; and indicating a leak in one of the first and second monitored pipes in response to detecting a pressure in the exhaust line outside of a first predetermined pressure range.
