Polypropylene pipe with low flow resistance and high stress resistance

The invention relates to the technical field of polypropylene pipes, and discloses a low-flow-resistance and high-stress-resistance polypropylene pipe which comprises a polypropylene pipe, and a dredging mechanism installed on a movable driving assembly is arranged on the side, close to the water inlet end, in an inner cavity of the polypropylene pipe. The movable driving assembly is installed at the axis of an inner cavity of the polypropylene pipe and penetrates through the inner cavity of the whole polypropylene pipe, a flow velocity detector installed on the movable driving assembly is further arranged on the side, close to the water outlet end, in the inner cavity of the polypropylene pipe, and a filter plate and a water pressure detector which are located on the outer side of the flow velocity detector are further arranged in the inner cavity of the polypropylene pipe. The outer wall of the polypropylene pipe is fixedly sleeved with a protection layer, and a control module is installed on the outer wall
