método e instalação de montagem de uma ponteira de conexão em um conduto tubular flexível, e, conduto tubular flexível destinado ao transporte de hidrocarbonetos

摘要

The invention relates to a method and installation (10) for mounting an end fitting on a flexible tubular pipe (12), said flexible tubular pipe (12) having a free end (14) and comprising an internal pressure sheath (24) made of a polymer material containing additives that can be exuded. The internal pressure sheath includes an annular edging (28) and said annular edging includes an internal wall (31) opposite an external wall (33). According to the invention, the installation comprises: means for forming an annular chamber (47) inside the annular edging (28) along the external wall (33); means for forming an annular chamber (47) inside the annular edging (28) along the internal wall (31), said internal wall (31) forming an internal surface portion of the annular chamber; and means for circulating a fluid inside the annular chamber (47) in order locally to extract the volatile additives from the sheath annular edging (28) through the internal wall (31).
