Background

The excellent performance of the polyethylene pipe and the stability and reliability of a welding interface are important reasons for the wide application of the polyethylene pipe; however, with the increasing scale of travel projects and villa residential projects in recent years, the single connection form (hot melt connection and electric melting connection) exposes small problems in the sectional construction, and a welding type plugging pipe cap has to be adopted for temporary plugging after each sectional construction. The temporary plugging of the polyethylene pipeline with the pipe diameter more than or equal to DE90 can be realized by adopting injection molding plugging pipe caps for hot melt connection, and the plugging pipe caps can be repeatedly used without too many problems. However, the temporary plugging pipe cap of the polyethylene pipeline with the pipe diameter smaller than DE90 is only selected as an electric melting plugging pipe cap, and the plugging pipe cap can not be reused, so that one electric melting plugging pipe cap needs to be consumed for each temporary plugging, and particularly, the segmented construction is common in large-scale villa residential projects in recent years. The villa district not only the segmentation construction is many and the pipe diameter that the villa district adopted is less, and a large amount of segmentation constructions mean a large amount of pipe fitting material consumptions, not only to the construction cost control unfavorable and the plastics rubbish that produces also very unfriendly to the environment.
