WebRigid and flex grooved couplings tested leaked at 70% of table capacity. Threaded joints leaked at 25% and 50% of table capacity (at onset of shaking). Conclusions. •Joints … Victaulic held the original patent (filed in 1919) for the first grooved mechanical pipe coupling as invented by Lieutenant Ernest Tribe. But what most people don’t realize is that, in the beginning, all mechanical couplings were “flexible pipe couplings.” It wasn’t until 1957 when the first grooved rigid pipe coupling was … See more The invention of the first grooved mechanical coupling was intentionally a flexible pipe coupling. In the early 1900s, there were four prominent industries that gained benefit from an alternative pipe joining method to … See more Because of the nature of flexible pipe couplings, systems that utilize a large number of them will need additional supports and ways to … See more
