Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline supports, and particularly relates to a support device for preventing deformation during the welding of internally supported pipelines. Background Art

[0002] Pipeline structures are used for pipelines that transport liquids, gases, or loose solids and their supporting and strengthening structures. When transporting loose solids, water or gas is used as the medium. Pipelines must be leak-proof and resistant to the temperature, pressure, corrosion, and wear of the transported substances. For example, pipelines for transporting crude oil and heavy oil are required to withstand a temperature of about 100°C; steam pipelines need to withstand a temperature of about 150°C. The working internal pressure of water supply pipelines is about 0.5 - 1.0 MPa; that of compressed air and steam pipelines is about 0.8 - 1.3 MPa. Pipeline structures also have to bear their own weight, the weight of the transported materials, and various external loads, such as soil loads, water loads, wind and vibration loads generated by wind, loads generated by people, vehicles, and construction machinery, temperature effects, and seismic effects, etc.

[0003] During the actual welding and installation process of existing internally supported pipelines, due to the general supporting effect of their supporting devices, pipeline deformation will occur during the welding of pipelines, ultimately resulting in the pipeline being unable to be used continuously, or requiring sheet metal processing, reducing the installation quality of the pipeline. Moreover, general pipeline supports are limited to single bottom support or top suspension, and cannot achieve multi-directional installation, thus causing the problem of low practicability.
