Description
Technical field
Submarine pipeline device is repaired the present invention relates to a kind of ocean engineering field, more particularly to a kind of submarine pipeline is serious
Split type hydraulic prosthetic device when damaged.
Background technology
There is dielectric corrosion, ship and throw in the submarine pipeline of ocean engineering field due to the particularity of its operating condition under water
Anchor, geological disaster and ocean development damage from third-party equivalent risk, and thus trigger submarine pipeline damage accident, submarine pipeline is once
After generation leakage or major injury, not only result in ocean water body pollution, petroleum resources and waste and offshore production interruption, but also
Can be to downstream and the normal production of terminal user is adversely affected.
The specific recovery technique of submarine pipeline and scheme are different because of its damage type and operating water depth, and that takes at present is main
Reparation means can be summarized as recovery technique under water and recovery technique waterborne.Wherein, mechanical closure and the closure of composite reinforcing material
For recovery technique under water, it the advantage is that operation is simple, the implementation cycle is shorter, available for reasons such as burn into mother metal defect, crackles
The caused pipe leakage without big mechanically deform, but when submarine pipeline serious damage occurs or has moderate finite deformation,
Effective closure is just difficult to repair.Lift method reparation is mainly a kind of recovery technique waterborne, be by damaged pipeline section under water
Two pipe ends after cutting are promoted to operation at sea wire bonding acting flange respectively after excision, finally descend water to complete connection, technology rule
Risk during having kept away under water, applies more in shallow water area at present, and it has the disadvantage that marine butt welding construction technology is complicated,
Operating risk is big, and lifting and lower water operation easily cause pipeline section local buckling and bent, it is often more important that the flow of the technology
Complex and repair time is longer.It is under water applied widely the characteristics of pipeline section Replacement and Repair technology, can completes to corrode or break
The various forms of submarine pipelines breakages such as split to repair, but have the disadvantage the production technology of this key spare parts of reparation mechanical connector
Grasp always in specialized company's hand abroad, the country does not form corresponding research and development also and ordered with production technology ability, and its foreign countries
The goods cycle is longer.
The content of the invention
