Description

Technical Field

[0001] The utility model relates to the technical field of pipeline production, and more specifically, to an anti-corrosion construction device for heat-insulating pipelines. Background Art

[0002] Pipeline anti-corrosion construction is an engineering process to protect pipelines from corrosion and damage. During use, pipelines may be eroded by various corrosive media and external environments. In order to extend the service life of pipelines and ensure their safe operation, anti-corrosion construction is crucial.

[0003] In the existing technology, the anti-corrosion protection of insulated pipes mostly adopts a polyurethane rigid foam insulation layer tightly bonded to the outer skin of the pipe, isolating the infiltration of air and water, and can play a good anti-corrosion role. However, after long-term use, the foam rots, and the pipe is in contact with the air, causing the pipe to be oxidized. In recent years, epoxy coal tar cold wrap tape with enhanced anti-corrosion level has appeared. Its construction is simpler than the six-oil and two-cloth operation used in traditional anti-corrosion. It only needs to wrap the above-mentioned cold wrap tape around the pipe once, so it has been widely used in pipeline construction.

[0004] To use epoxy coal tar cold wrap tape for anti-corrosion construction, it is necessary to wrap it around the surface of the pipeline. Currently, simple manual wrapping in pipeline tunnels not only has low operating efficiency, but also the tightness of the wrapping is difficult to ensure. At the same time, the existing anti-corrosion construction equipment is not convenient for replacing the anti-corrosion tape, which reduces the construction efficiency and convenience of anti-corrosion construction.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a thermal insulation pipe anti-corrosion construction device, which has the following beneficial effects:

The support frame is rotatably arranged on the support plate, and is supported by the support groove, support block and support rod, so that the tape roller can be easily installed and disassembled through the clamping block and the clamping groove, thereby improving the practicability of the processing device.
