Abstract
A coupling construction includes a coupling (1) and at least one high-pressure pipe (2) connected to the coupling. The high-pressure pipe includes an external revetment layer (3), a reinforcement layer (4) as well as an internal liner (5). The coupling furthermore includes a load transfer element (9, 10) which engages the external revetment layer (3), as well as a sealing (6, 14) which engages the liner (5). The reinforcement layer (4) includes a braided material (7, 8) whereby the external revetment layer (3) engages the braided material (7, 8) in such a way that shear forces can be transferred in a reliable way. A further advantage is that the load transfer element (9, 10) of the coupling (1) is positioned only on the outside of the pipe (2), as a result of which the internal volume of the pipe is free of flow restrictions.
