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

Embodiment Construction
[0015] The structure and operating principle of the subsea oil pipeline and its connection end provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0016] Such as figure 1 As shown, the structure diagram of the submarine oil pipeline provided by the present invention and its fixed connection end includes an inner rubber hose 1 for transporting oil and an outer rubber hose 2 at a certain distance therefrom, and the inner and outer rubber hoses are composed of Made of rubber material, in order to form a certain space between the inner and outer rubber hoses, a number of annular support frames 4 (such as figure 2 shown). In order to increase the weight of the oil pipeline, some counterweights 5 such as gravel and iron sand are added in the independent sealed chamber 3 . In addition, in order to improve the insulation performance of the oil pipeline and prevent the oil in the pipeline from becoming thicker ...

The invention belongs to the technical field of petroleum transportation pipes, in particular to a submarine oil transportation pipeline and a special connection end thereof. It constitutes the technical scheme of the submarine oil pipeline and its special connection end: the submarine oil pipeline is composed of inner and outer rubber hoses made of rubber materials with a certain distance apart, and a certain space is formed between the rubber hoses, and in this space A number of support frames are provided to divide it into several material chambers, and the material chambers are filled with counterweights or insulation materials; The tube jacket is composed of the outer core tube and the outer tube jacket stuck on the outer core tube. The above-mentioned submarine oil pipeline and its special connection end solve the problems of being easily corroded by seawater, poor in bending performance, easy to be suspended, broken, and easy to hang wax at the connection head due to the existence of variable diameter, which constitutes the problem of pipeline blockage. It can be widely used in oil transportation on the seabed.
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...
