Abstract
A pipe coupling assembly for use with at least one terminal end of a fluid transfer pipe having an inner tubular member for transferring fluid, an outer tubular member, and an interstitial space therebetween. The pipe coupling assembly comprises a transition coupling for attachment to the pipe to provide a first path for the transfer fluid in the inner tubular member and a second path for the transfer pipe's interstitial space, and a transition fitting for attachment to the transition coupling to provide separate access to the transfer fluid and the transfer pipe's interstitial space.
