ABSTRACT:
In a pipeline system having a plurality of pipe segments joining a fluid supply tank to a fluid dispenser, the invention includes a pipe coupling assembly for use on at least one terminal end of a fluid transfer pipe, where the transfer pipe has an inner tubular member for transferring fluid and an outer tubular member and an interstitial space there between. The coupling assembly comprises a transition coupling for attachment to the pipe segment to provide a first path for the fluid in the inner tubular member and a second path for the interstitial space. The coupling assembly further comprises a transition tube assembly for attachment to the transition coupling to provide separate paths for the transfer fluid and the interstitial space, where the interstitial space provides a means for performing leak detection or fitting integrity tests during application of either a vacuum condition or pressurized gas input via such selective access.
