Restrained Connections with Düker´s thrust resisting joint systems

Socket systems - economic and efficient

With flangeless plug-in socket- and thrust-resisting joint systems by DÜKER, cast iron pipes, fittings and valves are connected safely within all water pipelines – among each other as well as with plastic pipes. Both sealing and locking function are guaranteed by each system. Material and connection withstand high internal and external pressure. This even applies for longitudinal displacements due to traffic or ground movements. The thrust-resistant socket joint follows ground movements without transferring bending moments to the next pipeline component.

Besides technical advantages of the systems, there are additional positive features such as handling with fewer tools and reduced mounting time. Depending on the system, fewer fittings are necessary for the same length of line, or certain special fittings can be done without. Furthermore, the dismantling of the thrust-resisting joints and the immediate pressure test is possible. The post-isolation can be carried out in a better quality and the thrust-resisting joints are applicable even in narrow ditches. Concrete blocks are completely dispensable.
