If the parts of a drawing consist of jacketed pipelines, the jacket pipe is drawn as a hollow pipe to indicate the presence of the core pipe, and each connection between the jacket and core pipes are indicated with continuation references. The core pipes display continuation references for jacket pipes whereas jacket pipes display continuation references for core pipes.
To generate jacketed pipeline diagrams, make sure that the jacket and core pipe association has been established. See Placing the Jacket Pipe and Components in the Piping Help.
You must use the JFWN (weld neck jacket flange) and JFSO (slip on jacket flange) three-port flanges SKEYs for jacket flanges. See Flanges (SKEYs).
The example below shows a core pipeline drawing with a continuation reference for the jacket pipe.
