| 20140339810 | PRESSURE COMPENSATED ENCLOSURES FOR SUBMERGED JOINTS - Enclosures are described that encapsulate or surround a joint between two or more elements, for example two pipes or a pipe and a valve. The enclosures prevent direct contact between the joint and the surrounding water, for example fresh or salt water, and prevent biofouling and corrosion of the joint. An enclosure encapsulates the joint and forms an enclosed space around the joint. Some or all of the enclosure includes a flexible material. The enclosed space is filled with a protective liquid that is retained in the enclosed space and that will be in direct contact with the joint. Due to the flexible nature of the flexible material, the pressure inside the enclosed space is maintained substantially equal to the exterior pressure outside the membrane. | 11-20-2014 |
