Problems solved by technology

[0003] In the process of connecting conventional HDPE pipes with hot-melt extrusion welding composite heat-shrinkable tape, hot-melt extrusion welding is performed first, and then the heat-shrinkable tape is connected. During hot-melt extrusion welding, the ends of the two pipes need to be Alignment, the axis is straight before welding can be carried out. If the ends of the two pipes are not aligned and welded directly, it will cause misalignment of the connection between the pipes
[0004] In view of the above-mentioned related technologies, the inventor believes that in the actual construction process, in order to prevent the occurrence of connection misalignment between the pipes, the construction personnel need to repeatedly adjust and confirm when aligning the two pipes, and the construction personnel are repeatedly adjusting and confirming The process will consume a lot of time, making the construction efficiency low

Abstract

The invention relates to the field of HDPE pipe connections, in particular to a hot-melt extrusion welding composite heat shrinkable tape connected HDPE pipe. The HDPE pipe comprises a pipe body, wherein a plurality of containing grooves are arranged in one end face of the pipe body; a positioning rod is arranged in each containing groove; and a plurality of positioning grooves corresponding to the positioning rods are arranged in the end face, away from the positioning rods, of the pipe body. The HDPE pipe and a construction method thereof have the effect of improving the construction efficiency.

Description

technical field [0001] The present application relates to the field of connecting HDPE pipes, in particular to a hot-melt extrusion welding composite heat-shrinkable tape to connect HDPE pipes and a construction method thereof. Background technique [0002] HDPE pipe is a pipe made of high-density polyethylene material. Hot-melt extrusion welding is a method of using a special hot air extrusion welding tool. First, the pipe is heated at the joint, and the welding torch extrudes molten polyethylene to melt the joint into one. Heat-shrinkable tape connection is to use fiber-reinforced polyethylene heat-shrinkable tape to wrap two pipes. The inner surface of the heat-shrinkable tape is coated with hot-melt adhesive. [0003] In the process of connecting conventional HDPE pipes with hot-melt extrusion welding composite heat-shrinkable tape, hot-melt extrusion welding is performed first, and then the heat-shrinkable tape is connected. During hot-melt extrusion welding, the ends ...
