[0002] Composite pipe is a pipeline system composed of multiple pipes, which is used to transport a variety of different fluids or substances. This pipeline system is usually composed of pipes of different materials and diameters. Different media such as liquids, gases, solids, etc. can be transmitted in the same pipeline system. Composite pipes are usually used in industrial production, chemical industry, oil and natural gas transportation and other fields, which can improve production efficiency and reduce costs.

[0003] When installing the composite pipe, the composite pipe needs to be transported to the construction site, and the composite pipe is moved to the designated installation position by machinery. When the composite pipe is constructed and installed, the pipe end is easily deformed and out of round due to various external forces. In order to ensure that the two sections of the composite pipe can be butted, the composite pipe with the deformed and out of round pipe end needs to be adjusted on the construction site. However, the existing adjustment process mainly relies on the staff to use tools to knock and reset the pipe end of the composite pipe, resulting in a low adjustment efficiency of the composite pipe.
