Technical Field

[0001] The utility model relates to the field of pipe wall thickness adjustment, in particular to a device for adjusting the wall thickness of a large-diameter pipe. Background Art

[0002] With the rapid development of my country's infrastructure construction industry, urban buildings are getting taller and taller, the demand for pipelines is increasing, and the output of pipes is also increasing. After the existing pipes are produced, a certain section of the pipe will be deformed due to the long length of the pipe, resulting in a difference in the wall thickness of this section of the pipe and the wall thickness at both ends of the pipe, which leads to a decrease in the physical properties of the entire pipe. The existing pipe wall thickness adjustment mostly relies on cutting the pipe and reinstalling the appropriate pipe on the pipe, but this method not only directly damages the pipe itself, but also relies more on the welding skills of the maintenance personnel themselves during maintenance, resulting in different maintenance personnel often producing different maintenance effects, which in turn affects the normal use of the entire pipe.
