Abstract
The present invention relates generally to an apparatus and method for preventing disbondment in an insulated piping system that is used for conveying high temperature fluids. More specifically, an external slip wrap is shown, capable of surrounding the outer protective jacket of the insulated piping system at a location along the piping before an elbow shaped or angular change in direction. The slip wrap comprises a loosely received outer sleeve which surrounds the outer protective jacket of the piping without being bonded thereto, thereby allowing the insulated and jacketed pipe to move axially relative to the slip wrap for a selected distance once the pipe is buried in the ground.
