[0001] This utility model relates to the field of pipeline reinforcement technology, and in particular to a reinforcement structure for a high-pressure steam pipeline used in chemical industry. Background Art

[0002] The main purpose of reinforcing high-pressure steam pipelines for chemical applications is to improve the pipeline's load-bearing capacity, stability, and safety, in order to address potential deformation and cracking issues that may occur under high pressure, high temperature, and corrosive environments. Reinforcing rings can be installed at weak points or areas prone to deformation to enhance the pipeline's load-bearing capacity.

[0003] Traditional existing technical solutions have the following drawbacks: When assembling high-pressure steam pipelines, several sets of bolts are usually used for assembly and fixation. This assembly and disassembly is inconvenient and requires operation of each set, which prolongs the construction period and increases construction costs. In addition, high-pressure steam pipelines are thermal pipelines, and they will undergo thermal expansion and contraction after passing through steam. The fixed connection used in the usual way cannot release the stress after the pipeline expands, causing the pipeline to deform or be damaged. Utility Model Content
