Submarine oil pipeline and dedicated connector therefor

Abstract

The invention relates to a submarine oil pipe line and the special connecting rod, belonging to oil transmission pipe technology area. The technology scheme constituting the submarine oil pipe line and the special connecting rod is that the submarine oil pipe line comprises inner and outer rubber hose made of rubber and with certain distance, there is certain space among rubber hoses and several supports divides the space to several material rooms, in which balance weight or heat insulation material is filled; the special connecting rod comprises core of inner pipe, sleeve of inner pipe clipped on the core of inner pipe, core of outer pipe and sleeve of outer pipe clipped on the core of outer pipe. Above mentioned submarine oil pipe line and the special connecting rod solve the problem of pipe blockage which is generated by seawater corrosion, easy overhead and breakage by bad bending performance and easily suspending wax by variable diameter at the connecting rod position. It can be applied in submarine oil transmission.

Description

technical field [0001] The invention belongs to the technical field of oil pipelines, in particular to a submarine oil pipeline specially used for oil transportation and a special connection end thereof. Background technique [0002] Oil transportation is mainly completed by pipelines, which have the advantages of safety and low cost, especially for underwater or seabed oil transportation across water areas, the advantages of safety and low cost are more prominent. But at present, the pipelines used to transport oil on the seabed mostly use rubber hoses that are resistant to seawater corrosion, or metal steel pipes. Laying the above two oil pipelines on the seabed has the following disadvantages: when metal steel pipes are used, they are easily corroded by seawater and have a short service life; in addition, due to their poor bending performance, the sea current in the seabed will wash away the sand under the metal steel pipes After the overhead distance reaches a certain v...

Problems solved by technology

Laying the above two oil pipelines on the seabed has the following disadvantages: when metal steel pipes are used, they are easily corroded by seawater and have a short service life; in addition, due to their poor bending performance, the sea current in the seabed will wash away the sand under the metal steel pipes After the overhead distance reaches a certain value, the pipeline is very easy to break, which will affect the transportation of oil; when the rubber hose pipeline is used, because of its light texture, the submarine pipeline is easily affected by the ocean current, floating and easily broken , which also affects the transportation of oil

In addition, because there is a variable diameter at the connecting end of the oil transportation pipeline, that is, the inner diameter of the connecting end is smaller than the inner diameter of the pipeline. There are problems of unsmooth and low efficiency in the transportation
