Using the rolling ring construction pipes going onto the wall should be provided with a guide-way in order to
allow the ring to roll between pipe and wallcasting. The diameter of the guide-way should be a minimum of:
the outer diameter of the pipe + 2x diameter of the O-ring.

The wall penetration consists of a steel pipe provided with flanges. One of these flanges is profiled to fit
the shape of the sealing element. By tightening the nuts the seal will be pressed in the wedge-shaped space
between flange and pipe, thus creating an excellent seal.

When a pipe has to pass through a wall, the outside of the pipe must be protected by a flexible material
(a rubber layer, with a minimum thickness of 5 mm) protruding some 100 mm outside the wall at each side.
In order to allow for setting of the adjoining pipe sections, flexible couplings must be installed on both sides
of the wall. Joints must not be located at a distance of more than 1 x ID outside the wall, with a maximum
of 0.5 m.
