HDPE Siphon Drainage Pipe

Dedicated pipe for roof siphon rainwater systems, using building height difference to create negative pressure for full-bore drainage. Horizontal suspended runs need no slope, reducing downpipes; tough, corrosion and aging resistant with fusion-welded joints.

HDPE Siphon Drainage Pipe

HDPE siphon drainage pipes are designed for roof siphon rainwater systems, using negative pressure generated by building height differences to achieve full-bore drainage with high efficiency. The suspended pipes need no slope and can be laid horizontally, reducing the number of risers and saving building space. Tough, corrosion-resistant and ageing-resistant, they use heat-fused joints for stable sealing. Widely used for flat roof rainwater drainage in factories, shopping malls and residential buildings.
