Abstract: An elastomeric sealing device operable at an operating temperature above an installation temperature. The sealing device includes a body fabricated from an elastomeric material. A channel is formed within the body. A mesh is disposed within the channel. The mesh includes a plurality of interwoven fibers forming an inner volume. A filler is disposed within the inner volume. At least a portion of the filler is a liquid at the installation temperature. The at least a portion of the filler is a gas at the operating temperature.

Abstract: The present invention provides an insulated fluid conduit useful in facilities in which a hot fluid susceptible to one or more deleterious phase changes in response to heat loss to a cold environment is transported. Such conduits may be particularly well suited to improve thermal control in subsea hydrocarbon production operations. The fluid conduit includes an inner first insulating layer containing a first polymer matrix, and a first phase change material undergoing a phase change at T1. The fluid conduit includes an outer second insulating layer containing a second polymer matrix, and a second phase change material undergoing a phase change at T2, wherein T1 is greater than T2. One or more barrier layers inhibit migration of the phase change material from the insulation layers and into the environment. In one or more embodiments, the phase change material is present as a microencapsulated phase change material.

Abstract translation: 本发明提供了一种绝缘流体管道，其用于能够响应于对寒冷环境的热损失而易受一个或多个有害相变化的热流体的运输的设备。 这样的导管可能特别适合于改善海底碳氢化合物生产操作中的热控制。 流体管道包括含有第一聚合物基质的内部第一绝缘层和在T1下经历相变的第一相变材料。 流体管道包括含有第二聚合物基质的外部第二绝缘层和在T2处经历相变的第二相变材料，其中T1大于T2。 一个或多个阻挡层抑制相变材料从绝缘层迁移到环境中。 在一个或多个实施方案中，相变材料作为微胶囊相变材料存在。
