Estudo da aderência de arames da armadura de tração em conectores de dutos flexíveis

Abstract

This project aims to present the study of tensile armor wires usually employed in the transport of oil, gas and hydraulic umbilicals in the petroleum industry. This study was developed as a need for better anchoring of the tensile armor wires in order to guarantee that even after the rupture of the wire within the connector it will not slip causing the fall of the flexible riser. Thus was established the adhesion study of the interface of the tensile armor wires of the flexible risers. After the end of the tests a new procedure for improving mechanical adhesion between the wires and the epoxy resin was studied. After the end of the adhesion tests tensile test was performed on each wire of the tensile armor under its mounting on the end fitting for checking the loading that reaches the hook of the armor wires. The trials performed in the 2.5 end fitting show that the tensile armor wire hooks are of great importance for the structural integrity of the flexible riser, as there is no contact between the resin cone formed within the end fitting and the tensile armor wires area.
