Connectors for the reinforcement of the traction of steel cables in ducts flexu00ecveis employed in the oil industry

摘要

Connectors stop armor traction with steel cables in ducts flexu00ecveis employed in the oil industry. The present invention aims to allow the connection of the flexible pipelines with valves traction steel ropes and cables coated or not in structures or other pipes.Two pieces, one inside the other, transmit to the wires embedded in a resin compressivos efforts that allow the increase of the arcoragem mechanics, at the same time that distribute the traction tensions along the cables within the connectors.The use of this type of connection has the potential to increase performance in fatigue of the ducts with the reinforcement of tensile steel ropes and cables, and accordingly, the service life of the flexible pipelines with this configuration of the armor. The structural parameters, such as the dimensions and angles are defined by an optimization process that will involve numerical simulation and laboratory tests.
