In this structure, the pipe body 3 is extruded as a whole, and the second reinforcement layer 5 and the first reinforcement layer 6 are embedded in the pipe body 3 to enhance the structure of the pipe body 3. A spiral inner wall 301 is provided inside the pipe body 3. The design of the spiral inner wall 301 can change the path of the water flow, reduce turbulence and impact in the water supply pipe body 1, and achieve the purpose of noise reduction.

This structure makes the second reinforcement layer 5 and the first reinforcement layer 6 adopt metal materials, and the second reinforcement layer 5 and the first reinforcement layer 6 are staggered and overlapped, so that the second reinforcement layer 5 and the first reinforcement layer 6 have a covering property on the water supply pipe body 1, ensuring the structural strength of the water supply pipe body 1, and at the same time making the pipe body 3 able to be integrally formed, and the outside of the pipe body 3 is provided with A circle of sound-absorbing layer 4, the sound-absorbing layer 4 is made of polyethylene foam, and the sound-absorbing layer 4 is integrally provided with a connecting layer 401 at the outer groove portion of the tube body 3. This structure provides a reliable positioning structure for the sound-absorbing layer 4 through the outer groove structure of the tube body 3, so that the sound-absorbing layer 4 is tightly relative to the tube body 3 through the connecting layer 401, so that the tube body 3 has a sound-absorbing function. The sound-absorbing layer 4 is extruded by low-density polyethylene foam and has good cushioning and sound absorption. The outside of the sound-absorbing layer 4 is also provided with a pressure-resistant outer ring 2, and one end of the pressure-resistant outer ring 2 is integrally provided with a flared connecting end 201, and the connecting end 201 is connected to the pressure-resistant outer ring 2.
