When replacing wastewater sewers that are no longer hydraulically adequate with larger-diameter pipes, the household connection points remain in place. If retrofitted connections or incorrectly executed connections with low inflow to the main sewage pipe exist, these can be replaced using eccentric (repair) junctions without sockets. Such situations call for connection solutions capable of flexible application, and that allow precious “height” to be gained.
For situations like this, we offer custom-made, high-precision fittings with diameters from DN 250 to DN 800 with inlet connections of DN 150/200/250, depending on diameter. Larger diameters for special cases can also be arranged if necessary. The inlet is manufactured at 90°, perpendicular to the main pipe axis. For junctions up to DN 350, a 45° version is also possible on special request.
The junctions can be finished in four versions with different “e” values, with connecting pipes available both with and without socket. For socket junctions, differentiation into right and left junctions (relative to direction of flow) has to be taken into account. Socketless junctions are installed using flexible couplings. Socket junctions use joint system C with K-joints made of PU.
Joint system inlet connections with socket:
DN 150 L-joint (system F) / DN 200 L-joint or K-joint (system C)/from DN 250 K-joint
Inlet load classes:
From DN 200, inlets are available in both normal or extra strength versions. Inlet connection options: with corresponding adapters/couplings, house connections covering a variety of materials that can be connected.
