This type of pipe has a structure of five layers:the inner and outer layers are made of PPR, which are tightly bonded with PP-based adhesive to the mid-layer of aluminum, which is well joined through welding.

Greatly reduced linear expansion coefficient,only 1/4 of  that of PPR.Improved resistant to impulse under low temperature, resistant to UV-ray.Can work under higher temperature and higher pressure.
