System for the assembly of a metal joining-piece and a high-pressure composite material tube - notably applications for equipment used in the oil industry

摘要

Device to permanently link a metal joining-piece and a composite material tube, to a tube subjected to static pressure up to 150 MPa. The assembly consists of a metal part constituting a sealing (8) and joining (7) piece with a collar (2), onto which the composite material (1) is attached. A tubular anti-abrasion and anti-corrosion (6) sleeve, flush-mounted in the metal joining piece and protected by a ring (9) at its end ensures total isolation of the composite/metal joint from corrosive fluids which may be flowing through the tube. In particular, the application of the device to oil industry sensors.
