Flexible pipe joint with function unit

Abstract

The invention provides a flexible pipe joint with a function unit, and solves the technical problem that an existing conventional joint form cannot meet the use requirement of a flexible pipe with the function unit. The flexible pipe joint comprises a joint body, wherein a fluid channel is formed inside the joint body; an internal plugging tube part capable of being plugged into an opening of the flexible pipe is arranged at one end of the joint body; one or multiple annular sealing wedge blocks are arranged in the outer circumferential direction of the internal plugging tube part; an annular joint sleeve is arranged in the outer circumferential directions of the sealing wedge blocks; the shape of the inner wall of the joint sleeve is matched with the shapes of the outer walls of the sealing wedge blocks, and the inner wall of the joint sleeve is in close fit with the outer walls of the sealing wedge blocks; one or multiple reserved channels are formed in the wall of the joint body; an opening in one end of each reserved channel is formed in the tail end of the internal plugging tube part, and an opening in the other end of the reserved channel is formed in the outer side wall, which is away from the direction of the internal plugging tube part, of the joint body; a transitional function unit is arranged in each reserved channel; and two ends of each transitional function unit are respectively arranged at the openings in two ends of each corresponding reserved channel. The invention can be widely applied to any flexible pipe joints with function units.

Description

technical field [0001] The invention relates to a flexible pipe joint, in particular to a flexible pipe joint with functional units. Background technique [0002] With the large-scale exploitation, storage and transportation of land and sea oil and gas, the corrosive medium, minerals and halogens in oil and gas will have a great corrosion effect on the transmission steel pipe, and it needs to be replaced in 2 to 3 years. As an emerging product in the oil and gas transportation industry, flexible pipes have the advantages of better corrosion resistance, better flexibility, light weight, and easy laying than steel pipes. At present, more and more oil fields are beginning to use flexible pipes instead of steel pipes. Due to its special manufacturing process, the flexible pipe can add functional units, that is, lay out optical fibers, cables and other units in the flexible pipe structure, so as to realize the power supply and status monitoring of the flexible pipe connection equ...

AI Technical Summary

Problems solved by technology

The threaded connection needs to rotate the pipe joint, and the functional unit is usually fragile and cannot be rotated with it, so it is easy to be torn off; the buckle connection is easy to break the functional unit near the outer layer; the heat-melt sleeve connection is easy to overheat the optical fiber unit damage; the traditional mechanical connection cannot guarantee the tightness of the joint; the umbilical cable connection, the joint structure is very complicated, and the size is too large, which limits the application range of pipeline products
