[0002] Plastic pipelines refer to the general term for pipes made of plastic materials. Plastic pipelines have the characteristics of light self-weight, hygienic safety, small water flow resistance, energy saving, metal saving, improved living environment, long service life, safety and convenience, etc., and are favored by the pipeline engineering field. During the pipeline connection and installation process, it is necessary to butt-connect the joints of two plastic pipelines. There are various plastic pipeline butt-joint methods, which can be hot-welded or connected by joint connection methods.

It includes a clamping head sleeved outside the plastic pipe and a butting device. The butting device is connected to the clamping heads on both sides of the plastic pipes at the same time. The end of the plastic pipe is bent outward to form a butting part arranged around the end of the plastic pipe, and the butting parts of the two plastic pipes are hermetically connected. The butting part of this double-press head fully-sealed joint for plastic pipes is hermetically connected, thus avoiding direct contact between the butting device and the liquid transported inside the plastic pipe, preventing damage to the butting device caused by the liquid transported inside the pipeline, and further avoiding pollution to the liquid transported inside the pipeline, and also extending the service life of the plastic pipe.
