Abstract
PURPOSE: To achieve the stagilization of oil leakage detection and the improvement in sensitivity by flowing a gas between the outer and inner pipe of an oil transport pipe and detecting the oil having leaked into the gas with the detectorsinstalled at a fixed interval to the pipeline.
CONSTITUTION: An outer pipe 2 which hermetically seals an inner pipe 1 is provided on the outside of the inner pipe 1 for transporting specified fluid. At every constant interval of this pipeline, a partition wall 3 which cuts off the spacing 4 between the inner pipe 1 and outer pipe 2 is provided. Between the adjoining spacing parts 4 are communicated by a bypass pipe 5. A leakage detector 6 is provided to the bypass pipe 5. Air or inert gas is flowed at all timesor within a fixed time in the spacing part 4 and if oil leaks as the inner pipe bursts, the leaking oil is carried in the gas and is detected with the liakage oil detector 6. In this way, the detection of oil leakage is sure and is accomplished with good sensivivity.
