Umbilical cable test joint and installation method thereof

Abstract

The invention relates to an umbilical cable test joint and an installation method thereof. The umbilical cable test joint comprises a reverse tapered push plate with a small bottom opening and a big upper opening, wherein a plurality of locking screw holes are arranged on the edge of the outer edge of the push plate, a taper sleeve consisting of two half taper sleeves of a right taper body and a left taper body is sleeved in each tapered hole of the push plate, the top of the taper sleeve is provided with an annular pressing plate, the edge of the end face of the pressing plate is provided with through holes corresponding to the plurality of locking screw holes, a plurality of fastening screw holes are arranged at intervals, the top of the pressing plate is provided with a disk-shaped flange with a concave bottom, the center of the disk-shaped flange is provided with a plurality of connection through holes, the edge of the end face of the flange is provided with through holes corresponding to the screw holes on the pressing plate, a transition flange with an annular top and an annular bottom and a cylindrical middle is connected to the top surface of the flange, a flange disk on the top of the transition flange is provided with a plurality of through holes correspondingly connected with an experiment device, and a flange disk on the bottom of the transition flange is provided with a plurality of through holes correspondingly connected with the through holes of the flange. The umbilical cable test joint can be widely applied to a test process of an underground production system umbilical cable.

Description

technical field [0001] The invention relates to a cable connection joint, in particular to an umbilical cable test joint in an underwater production system and an installation method thereof. Background technique [0002] As my country's demand for energy continues to increase, efforts to extract oil and gas resources from the ocean are also being strengthened. In the process of energy mining and transportation, umbilical cables have been more and more widely used due to their advantages such as flexibility, corrosion resistance, convenient laying and recycling, and strong designability. Especially in the application of offshore oil development, the application of umbilical cables has gradually become a trend. Umbilical design is a complex task that requires consideration of various loading conditions, and each umbilical must be individually designed to meet specific requirements under different environmental loads. Therefore, after the sample cable is manufactured, a larg...

AI Technical Summary

Problems solved by technology

However, the test joints in the prior art have the following problems: 1. The outside of the sample cable can only be fixed, and only the tension and bending of the sample cable armor layer can be tested, which cannot bear the torsional force well; 2. During the test, each unit inside the umbilical cable has no pre-tensioning force, and the relative movement is relatively obvious. There are large errors in the test results, and it is difficult to reflect the real situation.
