ABSTRACT:
A device is illustrated and described for connecting two ends of high-pressure pipelines for use in longwalls of underground mining, having a removable pipe coupling for tension-proof and tight connection of the two pipe ends whose constructions are tailored to one another. In order to counteract the catching as the pipeline is displaced in the longitudinal direction, so that damage or even destruction of the pipeline or pipe connections may be reliably prevented, each pipe end is reinforced using an essentially conical ring, whose outer surface expands from the external diameter of the pipe up to the external diameter of the pipe coupling.
