| Abstract Scope |
The lifespan of the general District Heating (DH) pipe is about 30 years, and a significant amount of the buried district heating pipe is nearing the time of replacement. A district heating pipe used for a long time may cause a defect in a vulnerable area as heat contraction and expansion are repeated, and this could lead to a personal accident as the district heating pipe is ruptured, so it is essential to replace it at an appropriate season. Currently, the district heating pipe has been replaced depending on the worker’s know-how, so the quality of the welding part is not uniform, and the work take a considerable amount of time. In this paper, we propose an automated equipment that uniformly heats the polyethylene outer pipe and then seals the joint in the electric fusion welding method, and proposes an optimal construction method for quality uniformly. |
