Abstract
A PIP Trace Heating Connection Assembly A pipe-in-pipe (PIP) trace heating connection assembly in the annulus of a PIP pipeline comprising at least first and second conjoined PIP stalks having inner and outer pipes and the annulus thereinbetween, the first PIP stalk having a first trace heating cable (22) located along its inner pipe, and the second PIP stalk having a second trace heating cable (24) located along its inner pipe, the first and second heating cables have cable ends and heating cable terminals on the cable ends, and a flexible intermediate connecting cable (40) having first and second intermediate terminals secured to, the heating cable terminals of the first and second trace heating cables respectively to form a secured electrical pathway between the first and second trace heating cables. In this way, securing the heating cable terminals with the intermediate connecting cable significantly reduces the time required to form a secured electrical pathway between the trace heating cables of each PIP stalk.
