Abstract
PURPOSE: An inactive gas of pressure higher thsn the pressure of dangerous fluid being converyd in inner pipe is sealed between outer pipe and inner pipe and the differential pressures between the fluid pressure in the inner pipe and the pressure of the gas sealed between teh outer pipe and the inner pipe are measured, whereby leakage can be detected at high accuracy.
