Problems solved by technology

The existing optical fiber sensing and monitoring technology is to lay an optical cable separately along the outer surface of the pipeline, which additionally increases the project cost
Moreover, since the optical cable is directly laid on the outer surface of the pipeline, it is easily affected by external interference, resulting in low sensitivity and accuracy of the monitoring system

Abstract

The invention discloses a composite oil gas flexible pipe with fiber communication and monitoring functions, and relates to the field of an oil gas transmission pipeline. The composite oil gas flexible pipe comprises a metal flexible pipe, the metal flexible pipe is externally provided with an inner sheath for protecting the metal flexible pipe, a plurality of flat steel bands encircle the inner sheath, one of the flat steel bands is internally provided with an optical cable, and the plurality of flat steel bands as a whole is externally clad by an oversheath; and the composite oil gas flexible pipe has the fiber communication and monitoring functions at the same time. The composite oil gas flexible pipe is internally integrated with the optical cable, the fiber communication and monitoring functions are satisfied, and the engineering cost is also reduced at the same time. Besides, since the optical cable is disposed inside the oil gas flexible pipe, the optical cable is not easily affected by external interference, the real-time time of the oil gas flexible pipe can be rapidly and accurately monitored, and the sensitivity and the accuracy of a monitoring system are improved.

Description

technical field [0001] The invention relates to the field of oil and gas transportation pipelines, in particular to a composite oil and gas hose with optical fiber communication and monitoring functions. Background technique [0002] Oil and gas transportation is closely related to the national economy and people's lives. In order to ensure the safety of oil and gas pipeline transportation, oil and gas pipelines need to be monitored. At present, a variety of monitoring technologies for oil and gas pipelines have been developed internationally. With the rapid development of optical communication technology, especially the wide application of optical fiber communication and optical fiber sensing monitoring technology in various industries, optical fiber sensing monitoring technology is also widely used in the monitoring of oil and gas pipelines. In the existing optical fiber sensing and monitoring technology, an optical cable is laid separately along the outer surface of the ...
