Geberit Supertube

The space gaining system

Hydraulically optimised drainage of high-rise buildings

Geberit SuperTube technology is based on the perfect interplay between 3 system components – Sovent, BottomTurn Bend and BackFlip bend. Three clever fittings coupled with the tried-and-tested Geberit HDPE discharge pipe with its high load-bearing capacity combine to create an innovative hydraulic solution that enables waste water systems to be installed in a particularly space-saving manner in high-rise buildings. SuperTube means no requirement for parallel ventilation pipe, creating more usable space for the residential apartment owner and therefore gaining more floor space.

More additional benefits include - pipelines with consistently smaller dimensions allowing smaller pipe ducts to be used. Horizontal pipelines can be laid to a length of up to six metres without a slope to save even more space.

Space saving installation

The comparison illustrates the difference:

A conventional discharge pipe (illustration on left) achieves a discharge capacity of 12.4 l/s with pipe dimensions of d160 and an additional d90 ventilation pipe.

With Geberit SuperTube (illustration on right), the discharge capacity is 12 l/s. This technology facilitates a consistent discharge pipe with a pipe dimension of d110, meaning there is no need for a ventilation pipe. What's more, the horizontal pipelines can be laid to a length of up to six metres without a slope.

Perfect interplay

The outflowing water is set in rotation in the Geberit PE Sovent fitting.

Producing the swirl in the flow

The outflowing water is set in rotation in the Geberit HDPE Sovent fitting.

Flow in the Geberit HDPE BottomTurn

Maintaining the column of air in the event of a change in direction

The annular flow becomes a layered flow in the Geberit HDPE BottomTurn bend.

Flow in the Geberit HDPE BackFlip bend

Without disrupting the column of air in the vertical direction

The layered flow becomes an annular flow once again in the Geberit HDPE BackFlip bend.

Fittings

Geberit HDPE Sovent fitting d110

The optimised product geometry of the Geberit HDPE Sovent fitting guides the water into the stack and sets it in rotation, which causes it to press against the pipe wall. The resulting annular flow creates a stable, continuous column of air on the inside, which facilitates a discharge capacity of 12 l/s.

Geberit HDPE BottomTurn bend

With the Geberit HDPE BottomTurn bend, a change in direction causes the wall of water to break and the annular flow to become a layered flow without disrupting the column of air. This change significantly reduces impulse losses compared with conventional solutions.

Geberit HDPE BackFlip bend

The twisted Geberit HDPE BackFlip bend causes the layered flow of water to swirl, which allows it to rotate through the vertical pipeline as it drains away in an annular flow. The inner air column in the subsequent stack is maintained.
