Problems solved by technology

[0002] When plastic pipes are connected to each other, they often encounter poor fit. This is because the surface of plastic pipes is prone to pollution and scratches during storage and transportation, which leads to unreliable connections during installation.
In today's market, there is no tool that can effectively and evenly remove the pollution layer on the surface of small-diameter plastic pipes. At present, there are equipment for removing the pollution layer at the joints of large-diameter plastic pipes, but these devices are only suitable for large-diameter plastic pipes. Small-diameter pipes are not suitable; under normal circumstances, for small-diameter pipes, most of them use manual blades to remove the contamination layer. In terms of cutting volume and roundness, it depends on human touch and experience, and the processing quality is not good.
