Description

Technical Field

[0001] The utility model relates to the technical field of boilers and pressure vessels, in particular to a tube hydraulic correction device. Background Art

[0002] Elbow pipes are widely used in boilers and pressure vessels to increase the heat transfer area of the boiler water in the drum. Elbow pipes are generally formed by bending seamless steel pipes through a pipe bender. According to different boiler products, the required lengths of the elbow pipes are also different. When the length is too long, multiple elbow pipes need to be connected.

[0003] During the connection process of multiple elbow pipes, multiple already bent seamless steel pipes are welded. In the actual manufacturing process, the welded joints of the elbow pipes will be deformed and bent. In order to ensure the quality of the elbow pipes, the bent parts of the elbow pipes are corrected manually, which requires a high skill level of the operators and also has a large labor intensity for the operators to correct the pipes.
