How to install PE pressure systems
Group 3: Concrete encased systems
Pipe systems belonging to group 3 constitute exceptional cases, especially as the accessibility for maintenance is limited. If possible, a pipe line should be installed according to the principles of groups 1 or 2, and direct integration into structures be reserved for open channels or discharge pipes, which are subject to lower stress.
Pipe systems can also be installed so that an encasement in concrete walls, decks, foundations, etc is possible after completion of the installation. The concrete surrounding the pipe impedes length changes resulting from temperature fluctuations (e.g. due to the temperature of the flow medium or the effects of external temperature). Since no friction-type connection exists between the plastic pipe and the concrete, measures must be taken to protect individual pipe elements.
