Branches DN 100 and upwards can be fitted to all pipe sizes. Branches can be made from drainage materials other than concrete and are normally fitted to both full length and short length pipes to suit customer requirements.
Uni junctions are supplied fitted to pipes from DN300 up to DN 1800 and to suit 150mm diameter connections. The junction is produced by inserting a rubber gasket to BS EN 681-1:1996 into the main pipe at the factory, providing a watertight seal for the branch connection.
| The uni junction is:
• less susceptible to site and transport
damage
• able to accommodate a range of pipe
material using adaptors
• angular connections can be made by
using bends |
|
The uni junction is designed to suit 150mm slimline clay pipes. To connect to plastic pipes, an adaptor coupling from the clay to the plastic pipe will be required. Alternatively for certain plastic pipes an adaptor bush is available. Contact our Sales Office for full compatibility details.

Concrete surround recommended to all junctions (not uni-junctions unless at depth).
Uni junctions should be laid with the branch at an angle to the main pipe in the vertical plane but not vertically.

For connections to existing pipelines CPM can supply ‘FABEKUN’ junctions. The ‘FABEKUN’ junction offers specifier and installers a wide range of benefits due to its quick and simple installation providing a permanent sealed connection. It can also be offered pre-installed by CPM, ideal for multiple connections.
The ‘FABEKUN’ junction is available to suit DN160 and DN200 connections and is approved in the UK by WRc. |
