Description

Technical Field

[0001] The present invention relates to the technical field of anti-deformation devices and methods, and in particular to an anti-deformation device and method for tube shoe welding. Background Art

[0002] The assembly process of offshore engineering project modules involves the installation of various pipelines and pipe shoes. The main appearance of pipe shoes is divided into T-shaped supports and well-shaped supports. The upper end of the pipe shoe is fixed to the pipeline or guard plate with a fillet weld, and the lower end is placed on the upper surface of the steel structure such as the pipe support or steel section. The guide block is used for limiting. The main function of the pipe shoe is to provide support and positioning for the pipeline system. The following problems exist:

[0003] At present, some pipe shoes and pipelines and other components are installed in the prefabrication stage of the workshop. Some of them need to be welded during the assembly of the blocks due to factors such as the cumulative error of the bracket positioning or the late arrival of materials. Since the main appearance of the pipe shoe is divided into T-shaped supports and well-shaped supports, the upper end of the pipe shoe is fixed to the pipeline or guard plate with fillet welds, and there are many welds. Due to the uneven heating during welding, the welding shrinkage deformation occurs, resulting in uneven deformation of the lower free end face of the pipe shoe. The lower plane of the pipe shoe is often warped all around and cannot be in close contact with the lower end pipe bracket or structural parts. Additional manpower is required for pyrotechnic leveling or adding plug plates to adjust the gap. The rework of this process increases the construction cost.

[0004] When welding pipe shoes and components such as pipelines, an anti-deformation device is installed on the base of the pipe shoe to prevent the four corners of the pipe shoe from warping when welding the upper weld. However, most traditional anti-deformation devices are directly fixed to the pipe shoe base by screws, which are in close contact with the pipe shoe base and cannot be ventilated. The heat generated by welding cannot be dissipated in time, causing the temperature of the anti-deformation device to rise, deform, lose the clamping effect, and cause the four corners of the pipe shoe to warp.
