[0002] During the transportation of oil, natural gas, and other pipelines, the pipeline surface is often damaged for various reasons. Polyethylene heat-shrinkable repair sheets have become a commonly used material for pipeline repair due to their good corrosion resistance, insulation, and mechanical properties.
[0003] During manual application, the repair patch is first heated with a spray gun and then tightly bonded to the pipe surface. The operator then uses rollers to roll and press the repair patch, combined with intermittent heating, to ensure that the repair patch adheres tightly to the pipe surface and prevent air bubbles from affecting the connection between the repair patch and the pipe.
[0004] However, the manual operation steps for repairing pipe damage are quite cumbersome. When using a roller to squeeze the repair patch, one needs to hold the spray gun with one hand and roll the roller with the other, making the operation steps cumbersome and complicated, which reduces work efficiency.
[0005] Therefore, it is necessary to provide a polyethylene heat shrink repair patch applicator to solve the above-mentioned technical problems. Utility Model Content
