Description
Technical field
The utility model relates to a kind of insulation ocean petroleum pipeline, belongs to ocean petroleum pipeline technical field of structures.
background technique
At present, land petroleum production enters the middle and later periods, marine petroleum development will become the main path that obtains from now on petroleum resources, along with the increase of marine petroleum exploitation amount, the transport that relies on pleasure boat to carry out crude oil can not meet current needs far away, therefore Crude oil from CNOOC conveyance conduit will become main mode of movement, because ocean petroleum pipeline is generally routed to seabed, therefore can realize good insulation, anticorrosion be current main R&D direction.
Summary of the invention
The utility model aims to provide that a kind of structure is simple and direct, thermal insulation property, the good ocean of antiseptic property petroleum pipeline.This petroleum pipeline is to design for ocean environment specially, and by experimental demonstration and field practice in recent years, has stronger practicability.
The utility model is achieved through the following technical solutions:
A kind of insulation ocean petroleum pipeline, comprise the inner tube 1 for delivery of fluid, its special way is, be arranged with outer tube 2 in the periphery of described inner tube 1, and head and the tail two ends and the described inner tube 1 of described outer tube 2 are tightly connected, thereby make to have formed between described inner tube 1 and described outer tube 2 an airtight toroidal cavity 3, in order to make described toroidal cavity 3 there is the performance of insulation between described inner and outer pipe, described outer tube 2 is provided with the vacuum draw valve 5 that is communicated in described toroidal cavity 3 inside, utilizes vacuum draw valve 5 to vacuumize described toroidal cavity 3 inside; Be subject to the punching press of the various materials in seabed and the distortion that causes or impaired for fear of inner tube 1, described toroidal cavity 3 inside are also provided with the support ring 4 that axially spaced-apart is laid in described inner tube 1 periphery and is supported in described 2 interior weeks of outer tube, offer the through hole 4-1 that air-flow passes through on described support ring 4.
The periphery tube wall of described inner tube 1 offers outside thread, on described support ring 4, has internal thread, and described support ring 4 is rotatably connected in the periphery of described inner tube 1 by screw thread;
Because outer tube 2 is direct and contact with sea water, in order to improve body corrosion resistance and the working life of outer tube 2, the periphery of described outer tube 2 is coated with epoxy resin anticorrosive coat 2-1, is wound with PE(polyethylene in the periphery of described epoxy resin anticorrosive coat 2-1) band;
In order to strengthen the head and the tail two ends of described outer tube 2 and the sealing of described inner tube 1, at the head and the tail two ends of described outer tube 2 and the joint of described inner tube 1, the seal ring 6 of carbon fiber enhancing under water is also installed;
What the inwall that described inner tube 1 contacts with fluid adopted is glass fibre reinforced plastics or nano-deposit.
A kind of insulation of the utility model ocean petroleum pipeline, reasonable in design is simple and direct, insulation antiseptic function admirable.The structure that adopts inner and outer tubes to socket-connect; in conjunction with vacuum draw, application of vacuum is carried out in two pipes centres simultaneously; form vacuum heat-insulating layer, therefore met the performance requirement of insulation, and space internal frame between two pipes is provided with support ring; outer tube is supported; inner tube is protected, reduced the damage of inner tube, improved the working life of inner tube; take corrosion-inhibiting coating processing in the outside of outer tube, the rotproofness of outer tube has also obtained good guarantee.
