| 发明名称 | Gas venting | ||
| 摘要 | An end fitting (300), flexible pipe (100), riser (203), and method of producing the same are disclosed. A method of venting gas from annuli (312, 319) of a flexible pipe is also disclosed. The end fitting includes a first vent flow fluid communication path (311) and a further vent flow fluid communication path (318). The end fitting is capable of enabling gas to be vented from a flexible pipe body with two annulus regions (312, 319). | ||

| 主权项 | 1. An end fitting suitable for venting gas from annuli of a flexible pipe body connected thereto, comprising: a first vent flow fluid communication path connecting in fluid communication an inner annulus region of the flexible pipe body and an exit port at an exterior of the end fitting; a further vent flow fluid communication path connecting in fluid communication an outer annulus region of the flexible pipe body and either the said exit port or a further exit port at the exterior of the end fitting; and a non-return valve provided in the further vent flow fluid communication path for inhibiting gas from entering the outer annulus region from the end fitting. | ||
