HDPE Drainage Pipe
  • The REHOME HDPE siphon roof rainwater drainage system is carefully calculated and designed according to the "Bernoulli" equation of fluid mechanics. After the installation of the entire system, the roof rainwater can be discharged at an amazing speed. The siphonic roof rainwater drainage system is the pressure flow rainwater drainage system. The system is designed to cause the negative pressure suction water flow in the suspension pipe, and the professional name is "siphonic system". The secondary suspension system, also known as the "energy dissipating suspension system", is a special energy dissipating and damping fixing device for the high water flow rate and strong vibration in the siphon system.

Advantages

  • (1) Less pipe consumption and less installation: The siphon roof rainwater drainage system effectively reduces the number of roof rainwater drainage systems, and the required pipe consumption, pipe diameter, ground excavation work, and on-site installation are also reduced accordingly.

  • (2) Increase the height of the indoor space and reduce the difficulty of construction: The siphon roof rainwater drainage system does not need to set a slope when installing the horizontal hanger, thereby increasing the height of the indoor space, reducing the difficulty of construction, and the quality is easy to control.

  • (3) Large drainage flow and fast flow rate: The siphon roof rainwater drainage system, because the pipeline rainwater flow is full and pressurized, the drainage flow rate is fast, the flow rate is large, and the roof water can be quickly discharged.

  • (4) Wide application range, long service life, low maintenance cost: The siphon roof rainwater drainage system is suitable for large-area and large-span roof drainage. The system has a long service life and can be used for more than ten years. Because of its low pipe consumption, the maintenance cost is correspondingly reduced.

Applications

  • (1) Indoor and outdoor drainage of high-rise buildings

  • (2) Bridge, elevated, road drainage

  • (3) Pressurized drainage of basement and submersible pump

  • (4) Underground buried pipes of civil air defense projects, connecting sections between communities and municipal supervisors, connecting pipes between the sea and islands or border defenses and other fields.
