Abstract (en)
[origin: GB2535741A] A pipe coupling for multilayer pipes comprises a body adapted for insertion into a pipe. The body has a through passage extending inwardly from at least two mouths 11, 12 and on its outer surface a groove 22 for receiving a sealing element 24 for forming a fluid-tight seal between an internal surface of the multilayer pipe and the body. Inwardly of the groove, the cross sectional area of the through passage 28 gradually increases, and can comprise a frusto-conical section with a cone angle of no more than twenty degrees. This reduces the pressure drop through the pipe coupling. The pipe coupling may be an elbow and may be formed from at least two, three or four separate parts attached together. Some of the parts may be formed via injection moulding.
