Rainwater Drainage Systems for External Floating Roofs

For the drainage of external floating roofs we offer two reliable techniques.


IMHOF, drainage of external floating roofs

1. Rainwater drainage via flexible drain hose

The flexible drain hose is the simplest form of rainwater drainage on floating roofs. The rubberised hose, with integrated fabric layers and helical wire spring, offers the necessary flexibility and resistance to wear and tear. The supply of the hose is complete with flanges, ballast weight, chain and clamp. If requested, we also supply the necessary protection cones for the hose, to be fixed to the bottom of the tank in the landing area of the roof legs.

Qualities of rubber available: Nitrile, Viton
Diameter of hoses: 3'', 4'', 6''






IMHOF, Rainwater drainage by articulated pipe systems

2. Rainwater drainage by articulated pipe systems

The key elements of this drainage system are flexible joints using composite hoses, 3”, 4”, 6” in diameter. The hoses are laminated with a number of highly resistant foil materials of PP, PETP or PTFE, backed by inner and outer helical stainless steel wire. The composite hose is protected against irreversible deformation by pivot-jointed metal bushes. If specified by the client, we supply the complete drainage system, including steel pipes with flange connections, sealing rings, etc.
