When people carry out the construction work of the heating project, pipelines will be used. A pipeline refers to a device connected by pipes, pipe connectors and valves, etc., for transporting gases, liquids or fluids with solid particles. The uses of pipelines are very extensive, mainly used in water supply, drainage, heating, gas supply, long-distance oil transportation, agricultural irrigation, hydraulic engineering and various industrial devices. However, due to the limited length of a single pipeline, it is necessary to weld and connect the pipelines to achieve the effect of increasing the pipeline length;
