The siphon roof rainwater drainage system is a new type of rainwater drainage system that uses a siphon rainwater bucket that can isolate the air and precise pipeline hydraulic balance calculation. Relying on the potential energy of the building, the rainwater flows through the closed pipe system to form a full pipe flow, and falls outside the riser to produce a siphon effect, which is a new rainwater drainage system that quickly discharges the rainwater from the roof.
The siphon roof rainwater drainage system is a relatively advanced roof rainwater drainage system in the world today. This system has a history of nearly 40 years. It is widely used in roofs with large spans and complex structures such as large factories, exhibition halls, airports, sports fields, and high-rise buildings. Since the current design considers more factors such as the appearance of the building, ease of construction, increasing the usable area and service life of the building, the traditional gravity rainwater system is becoming increasingly stretched and cannot meet the increasingly progressive design concepts. Instead, the siphon rainwater system can not only solve some design difficulties that the traditional gravity rainwater system cannot achieve, but also has advantages that traditional systems cannot match in terms of saving pipe materials and construction volume.
Excellent negative pressure resistance, suitable for siphon drainage conditions
Special high-rigidity HDPE raw material can withstand the negative pressure suction of the siphon system, and the pipe will not collapse or deform;
Comply with GB 50242, ISO 4427, ASTM D3350
The inner wall is super smooth, and the drainage flow rate is fast and it is not easy to accumulate.
The inner wall roughness is ≤0.007mm, the friction resistance is small, rainwater and sediment are quickly discharged, and there is no sedimentation and blockage;
Comply with ISO 10838, AWWA M55
High toughness, impact resistance, external force damage and temperature deformation resistance
