Zusammenfassung:The utility model discloses a PPR pipe resistant to low-temperature impact, and relates to the technical field of PPR pipes. In order to solve the problems of poor low-temperature resistance and poor impact resistance, the utility model discloses an inner pipe and outer pipe arranged on the periphery of the inner pipe, the outer surface of the inner pipe is provided with an annular chute, the inner surface of the annular chute is slidably connected with four sliding blocks, and the sliding blocks are arranged in the annular chute. The outer surface of the sliding block is rotationally connected with two first rotating rods, one end of each first rotating rod is rotationally connected with a second rotating rod, and one end of each second rotating rod is rotationally connected with the inner surface of the outer pipe; according to the PPR pipe, through the arrangement of the first spring and the second spring, when the outer pipe is impacted, the first spring and the second spring deform to buffer the impact f
