Description

Technical Field

[0001] The utility model relates to the technical field of municipal and metallurgical pipelines, in particular to a pipeline inner support anti-deformation device. Background Art

[0002] Metal pipe section deformation mainly involves the analysis of metal pipe bending and forming defects. During the production and installation process, metal pipes may be deformed due to the nature of the material, processing methods, environmental factors, etc., thus affecting their function and safety.

[0003] Welding is a key link in the manufacturing process of metal pipes, but the instantaneous stress during welding may cause welding deformation. In order to meet the design and specification requirements and prevent the occurrence of such welding deformation, correction must be performed. This correction is essentially trying to create new deformation to compensate or offset the deformation that has occurred. In construction production, the most commonly used methods for correcting residual deformation after welding can be divided into two types: force correction and heating correction.

[0004] In order to ensure the safety and stable operation of metal pipelines, these two correction technologies are often used together, but for large pipelines, correction is laborious and inefficient. This requires not only a deep understanding of metal materials and processing technology, but also the formulation of appropriate correction strategies and technical measures based on actual working conditions and production conditions.
