ABSTRACT:
This invention relates to a composite pipeline to be used in a submerged condition, usually in deep water. In accordance with this invention, the composite pipeline comprises a pipeline through which a fluid flows, e.g., oil, gas or a slurry; to provide for electrolytic protection, the pipeline includes a suitable coating or wrapping; finally, to enable the pipeline to be maintained in a submerged condition, an outer coating of concrete is provided about the wrapping. Further and in accordance with this invention, the concrete coating is integrally bonded to the pipeline in such fashion that the three element structure so provided can be said to be a composite structure rather than one made up of three separate elements. Because the composite structure pipeline is structurally one, it is possible to use a lighter weight of material in the pipeline with the result that a saving of as much as two-thirds of the pipeline weight is achieved.
