Description

Technical Field

[0001] The utility model relates to the technical field of non-metal compensators, in particular to a non-metal compensator insulation layer fixing device. Background Art

[0002] Non-metallic compensators are commonly installed in high-temperature pipelines in power plants, steel mills, and metallurgical industries. These compensators typically consist of a non-metallic outer sheath, nested left and right guide tubes, and an insulation layer between the guide tubes and the outer sheath. These insulation layers are flanked by left and right side panels, which are connected and secured to the guide tubes.

[0003] During the use of existing non-metallic compensators, the repeated thermal expansion and contraction of the pipeline will cause the insulation layer of the compensator to separate from the guide tube or side plate to form a gap, thereby reducing the thermal insulation effect of the insulation layer. The non-metallic skin will accelerate aging due to high temperature and corrosive gas, thereby reducing the service life and increasing the maintenance and use costs of the product.

[0013] As a preferred technical solution of the present invention, the left end of the left guide tube is welded and fixed to the left connecting pipe, and the right end of the right guide tube is welded and fixed to the right connecting pipe.
