[0003] During the laying and construction of PE gas pipelines, the pipelines need to be hot-melt butt-jointed. If the joint position of the pipeline and the pipe fittings deviates slightly, the molten plastic may not be evenly fused, leaving a tiny leakage channel. In addition, the uneven ground of the construction site will also cause deviations in the pipeline connection. Therefore, we need to design a connection device for the installation of PE gas pipelines, which adopts a relative motion structure and an anchor bolt adjustment structure so that the two pipelines can be accurately connected. During hot-melt connection, precise docking allows the pipelines to be evenly fused together after heating to form an almost seamless whole.

The anchor bolts can fine-tune the height, levelness and angle of the pipeline so that the butt end faces of the two pipelines can be accurately on the same horizontal plane, thereby ensuring the tightness and accuracy of the gas pipeline connection.
