... hazards 3. PiP overview Why PiP and key parameters A Pipe-in-Pipe system consists of the flowline (the inner pipe) inserted inside a carrier, or jacket pipe, often referred to as the outer pipe (see Figure 4 below). The created intermediate annulus is used to place so called dry insulation material...

... change. This paper is concerned only with the outer sleeve and internal thermal insulation, not the inner pipe. Sleeve Systems. The sleeve (or outer) pipe has a multi-purpose role in the design of a pipe-in-pipe system. Keeping the insulating material dry is one of the most basic problems when designing...
