[0002] High-temperature pipelines are devices connected by pipes, pipe connectors and valves for transporting high-temperature gas or high-temperature liquid fluids. During the installation of high-temperature pipelines, steel structure lugs are required to support and fix the high-temperature pipelines.

[0003] However, the existing steel structure lugs for high-temperature pipelines have a single structure and cannot timely buffer and offset the vibrations generated by the high-temperature pipelines during use, resulting in constant resonance between the high-temperature pipelines and the steel structure lugs. The resonance easily causes alternating stresses in the welds at the connections of the high-temperature pipelines, causing fatigue cracks, thereby affecting the service life of the pipeline connections. In addition, the insulation structure of the existing high-temperature pipelines is thin, resulting in the rapid loss of heat of the high-temperature gas or high-temperature liquid inside the high-temperature pipeline during transportation during actual use, resulting in poor thermal insulation.
