HDPE Siphon Pipe
Siphon rainwater drainage system is a new technology which is developed very fast in Europe, American, Japan, South-American, Asia and Africa countries. It is a more scientific and advanced technology, can be used on big construction building like factory, workshop, warehouse and public building. The inner drainage system has obviously advantages comparing with the traditional gravity current drainage system.

System CompositionThesiphondrainagesystemismainlycomposedofrainwaterhead,fasteningsystems,HDPEpipeandthecorrespondingdesignsoftware.System AdvantagesCompared with the traditional gravity drainage system, the siphon drainage system has advantages as follows:1. None-slope pipe.2.Lessmaterial used.
4.Reducing therequirement of pipes’diameter.
6.The pipehasits self-cleaningfunction.
2. Smoothinnerwall andtiny frictionalresistance.
3. Thepressurelossis about30%lessthanthesteeltube, so smallerdiameter of HDPE pipe could be chose.
4.Health performance is good. No additives and no possibility of pollution of drinking water,ISO standard gradingpolyethylene material
level is0 (the lowest)and no mildew material. Compared with some other commonly used plastic material, PE is much mildew resistance and it could be used for a long time without fouling.
