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

Embodiment 1

[0032] This embodiment provides a composite oil and gas hose with optical fiber communication and monitoring functions. The composite oil and gas hose includes a metal hose 1, an inner sheath 2, several flat steel strips 3, optical cables 4, Outer sheath5. The metal hose 1 is made of several buckle-shaped steel strips, which are continuously clamped one by one. The buckle-shaped steel strips are made of stainless steel with a thickness of 3mm; the inner sheath 2 is made of high-density polyethylene, which is extruded by an extruder. The thickness is 3mm; there are two layers of flat steel strips 3 closely surrounding the inner sheath 2, and one layer of flat steel strips 3 that is close to the inner sheath 2 is arranged in a clockwise direction, and the other All the flat steel strips 3 of one layer are arranged in the counterclockwise direction. In a layer of flat steel belt 3 close to the inner sheath 2, there is a flat steel belt 3 with a wire groove 3a inside, and the wir...

Embodiment 3

[0036] This embodiment provides a composite oil and gas hose with optical fiber communication and monitoring functions. The composite oil and gas hose includes a metal hose 1, an inner sheath 2, several flat steel strips 3, optical cables 4, Outer sheath5. The metal hose 1 is made of several buckle-shaped steel strips, which are continuously clamped one by one. The buckle-shaped steel strips are made of stainless steel with a thickness of 5mm; the inner sheath 2 is made of high-density polyethylene, which is extruded by an extruder. The thickness is 3mm; several flat steel strips 3 are closely surrounded by two layers outside the inner sheath 2, and one layer of flat steel strips 3 close to the inner sheath 2 is arranged in a counterclockwise direction. All the flat steel strips 3 of one layer are arranged clockwise. In a layer of flat steel belt 3 close to the inner sheath 2, there is a flat steel belt 3 with a wire groove 3a inside, and the wire groove 3a runs through the e...

Abstract

The present invention relates to the field of oil-gas transport pipelines. Provided are a combined flexible oil-gas pipe having an optical fiber communication function and a monitoring function. The combined flexible oil-gas pipe comprises a flexible metal pipe (1). An inner protection sleeve (2) is disposed at the exterior of the flexible metal pipe (1) to protect the flexible metal pipe (1). Multiple flat steel strips (3) surround the inner protection sleeve (2). An optical cable (4) is disposed inside one of the flat steel strips (3). An outer protection sleeve (5) entirely encloses the multiple flat steel strips (3). The combined flexible oil-gas pipe has both an optical fiber communication function and a monitoring function. The combined flexible oil-gas pipe integrated with the optical cable not only provides the optical fiber communication function and the monitoring function, but also has reduced construction costs. Moreover, the optical cable is located inside the flexible oil-gas pipe and is less susceptible to external interference, so that a real-time state of the flexible oil-gas pipe can be rapidly and accurately monitored, thereby improving sensitivity and accuracy of a monitoring system.

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 ...
