An integrated pipeline and gas leak detection system including:a. an integrated section formed ofa. a carrier pipe;b. a tubular outer jacket surrounding the carrier pipe with an annular space between the outer jacket and the carrier pipe;c. a gas leak detection pipe ("Sniffer pipe") situated in the annular space generally parallel to the carrier pipe, the Sniffer pipe having a plurality of holes extending radially through its walls and axially spaced from each other, and d. thermal insulation material in the annular space and surrounding the Sniffer pipe, with opposite ends of the annular space closed.b. a suction device coupled to one end of the Sniffer pipe, the other end of the Sniffer pipe being closed, and pipe being closed, andc. a gas detection device situated between the suction device and the Sniffer pipe, whereby operation of the suction device sucks any gas leaked from the carrier pipe in through the apertures in the Sniffer pipe, then through the Sniffer pipe to the gas detector which detects the presence of the leaked gas. |
