Abstract

The invention discloses a marine flexible pipe coupling structure. The structure comprises a coupling cell, a seal ring, a wedge-shaped block and a flange extrusion ring block. The coupling cell comprises a left flange connecting end and a right flexible pipe connecting end which are integrally formed. The right flexible pipe connecting end further comprises an inner sleeve and an outer sleeve. Acavity with a right circular ring shape communicating with a middle taper ring shape is formed between the inner sleeve and the outer sleeve. The inner sleeve is sleeved with the connecting end of a flexible pipe. The seal ring is located inside the bottom of the middle taper ring shape of the cavity and sleeves the connecting end of the flexible pipe. The wedge-shaped block is tightly connected with the seal ring, is located inside the middle taper ring shape of the cavity and sleeves the connecting end of the flexible pipe. The flange extrusion ring block is tightly connected with the wedge-shaped block and sleeves the connecting end of the flexible pipe, and the portion, located on the left side of an intermediate flange, of the flange extrusion ring block is located inside the right circular ring shape of the cavity. The intermediate flange of the flange extrusion ring block is relatively fixed to the end surface of the outer sleeve. The marine flexible pipe coupling structure is simple in structure, convenient to produce and mount and good in sealing performance at the same time.

Description

technical field [0001] The invention relates to the technical field of marine oil and gas transportation equipment, in particular to a marine flexible pipe joint structure. Background technique [0002] Pipeline transportation is the main way of offshore oil and gas transportation in the process of offshore oil and gas exploitation. For long-distance transportation, pipelines can only be connected in sections, and the joints are very important for the safety of oil and gas transportation. [0003] Marine flexible pipe is a new type of pipeline structure, including bonded and non-bonded types. In order to monitor the condition of flexible pipes, optical fibers are usually built into the pipe body, but there is no engineering application in China at present. The design of flexible pipe joints needs to take into account factors such as the structure, sealing and performance of the joints, the feasibility of actual operation, the ease of processing, and the aesthetic appearance...
