Abstract

The invention discloses a flexible pipe for ocean, wherein the flexible pipe for the ocean comprises a skeleton layer, a lining layer, a compression resistance layer, an anti-pull layer and an outer protective layer from inside to outside. The skeleton layer is a metal skeleton layer with a supporting function, the lining layer and the outer protective layer are both plastic layers, the compression resistance layer comprises a metal support and a plastic substrate which covers the outer portion of the metal support, the anti-pull layer is a spiral fiber reinforced material belt, and the spiral fiber reinforced material belt is coiled on the outer wall of the compression resistance layer. Compared with the prior art, a plastic and metal common processing method is utilized in the flexible pipe for the ocean, and particularly the plastic and metal common processing method is utilized in the compression resistance layer, original flat steel coiling is replaced by the fiber reinforced material processing in the anti-pull layer, and the weight of the flexible pipe for the ocean is reduced correspondingly, and therefore the flexible pipe for the ocean is further convenient to transport and install.

Description

technical field [0001] The present invention relates to the technical field of flexible pipes, more specifically, to a flexible pipe for marine use. Background technique [0002] With the continuous development of offshore oil and gas fields, pipeline transportation technology has been widely used in the offshore oil industry. In the North Sea of ​​the United Kingdom, a long-distance natural gas and oil-gas mixed transmission pipeline has been built, which has greatly promoted the development of natural gas fields in the North Sea. In the Gulf of Mexico in the United States, the total length of submarine pipelines is 37,000km, connecting oil fields, natural gas and coastal onshore processing plants into a production, processing and sales system. Therefore, the normal operation of submarine pipelines promotes the development of oil resources in the Gulf of Mexico . In the more than ten years of my country's offshore oil development, 2500km of offshore pipelines have also be...
