ABSTRACT:
A technique for installing and replacing, if necessary, readily bendable electrical heat-tracing cable on and insulating a network of installed pipes including straight sections, straight joints, and elbow sections is disclosed herein. In accordance with this technique, initially provided heat-tracing cable is installed in individual continuous sections along the length of and adjacent to the straight pipe sections, joints and elbow sections. Routing guides are placed over and/or under lengthwise surfaces of at least those segments of the heat-tracing cable adjacent to the joints and elbows and retained in place along with the cable itself. With the cable and routing guides so retained, a layer of thermal insulation is placed over the network of pipes as well as the cable and routing guides so that opposite ends of individual cable sections are readily accessible for connection with the source of electrical power or a section of replacement cable.
