[0002] Chemical pipelines are widely used in the chemical industry to transport various gases and liquids. In chemical plants, different chemical substances need to be transported. Therefore, when installing chemical pipelines, it is necessary to design the layout and direction of the pipelines in advance. When producing chemical pipelines, it is necessary to pre-weld pipe sections of various shapes and directions in the workshop, and finally transport the prefabricated and welded chemical pipelines to the production site for assembly and welding to form a complete chemical transmission pipeline. When welding chemical pipelines, it is necessary to align the two ends of the pipeline to be welded, and then weld them through welding equipment. However, most of the existing chemical pipeline welding devices can only dock straight pipes, and when welding straight pipes and curved pipes, specific clamping devices need to be used for docking, and after a section of curved pipe is welded, it is necessary to use an external hanger for transfer. When welding curved pipes in different directions, it is necessary to continuously adjust the curved pipe clamp, which makes the welding efficiency low in actual welding and inconvenient for continuous curved pipe welding.
