Abstract
The invention relates to a crosslinked polyethylene work pipe fitting elbow for a directly-buried heat preservation pipe intelligently prefabricated, and a manufacturing method. As the steel-made heat preservation pipe elbow manufacturing process is universally adopted for three-level pipe network cooling and heating at home, when installing is carried out in a corridor of a community unit, continuous section cutting and welding are needed, the construction difficulty is greatly increased, a great deal of economic loss of the construction cost is generated, a great deal of unnecessary loss in the aspect of heat consumption is caused, and the problems of steel pipe rusting and operation faults exist in pipeline conveying. The crosslinked polyethylene work pipe fitting elbow comprises a crosslinked polyethylene work pipe fitting elbow body (1). A PE outer protecting pipe (3) is arranged outside the crosslinked polyethylene work pipe fitting elbow body in a sleeving mode. A polyurethane heat preservation layer (2) is installed in the PE outer protecting pipe. Two alarm wires (4) and the crosslinked polyethylene work pipe fitting elbow body are each installed in the polyurethane heat preservation layer. The crosslinked polyethylene work pipe fitting elbow is used in the directly-buried heat preservation pipe intelligently prefabricated.
