Description
Technical field
The present invention relates to a kind of cable jointing, particularly test with joint and installation method thereof about the umbilical cables in a kind of subsea production system.
Background technology
Along with the continuous increase of China to energy demand, the dynamics of from the ocean, extracting hydrocarbon resources is also in continuous reinforcement.Advantage has obtained application more and more widely and in energy extraction and the process that transports, umbilical cables is flexible with it, anticorrosion, convenient-laying and recovery, designability are strong etc.Particularly in the application of marine petroleum development, the application of umbilical cables becomes a kind of trend gradually.Umbilical cables design is one to be needed to consider various load situation than complex task, and each umbilical cables all will design separately according to concrete actual conditions, to meet the specific requirement under the varying environment load.Therefore, after the appearance cable completes, need carry out a large amount of tests, confirm the reliability of its performance.The test of using at the umbilical cables two ends just has crucial meaning with joint.And there is following problem in test of the prior art with joint: 1, can only fix the outside of appearance cable, can only test specimens cable armor receive situation such as pulling force bending, can't well carry twisting resistance; 2, inner each unit of umbilical cables does not have pre-tensioning when test, and it is comparatively obvious to relatively move, and there is bigger error in test result, is difficult to embody real conditions.
Summary of the invention
To the problems referred to above, when the purpose of this invention is to provide a kind of outside armor and fix, cable core is fixed the appearance cable, make umbilical cables test that umbilical cables can bear tension force and torsion with joint and installation method thereof.
For realizing above-mentioned purpose; The present invention takes following technical scheme: joint is used in a kind of umbilical cables test; It is characterized in that: it comprises an end young big back taper cover shape suitable for reading push pedal; The edge of said push pedal outer is equipped with some locking screws, the conical sleeve that sheathed one a right cone and a left cone two halves tapered sleeve are formed in the bellmouth of said push pedal, and said conical sleeve top is provided with an annular pressing plate; The edge of said pressing plate end face is provided with the corresponding through hole of locking screw in the some and said push pedal; And be arranged at intervals with some fastening screws simultaneously, the top of said pressing plate is provided with the disc flange that a bottom is a concave bottom, and the center of said flange is provided with some connecting through holes; The edge of said end face of flange be provided with said pressing plate on the corresponding through hole of screw; The end face of said flange is connected with one, and upper and lower the orchid dish at said counter flange top is provided with the through hole of some corresponding connections with experimental facilities respectively for being counter flange cylindraceous in the middle of the annular, and the bottom orchid of said counter flange is coiled the through hole that is provided with the corresponding connection of through hole of said flange.
The top of said conical sleeve is provided with and is circular-arc.
The center pit of said pressing plate is the young taper hole in the big end suitable for reading.
Said extension test uses each parts of joint all to adopt material to be made as high-tensile structural steel.
Above-mentioned umbilical cables test is with the installation method of joint, and it may further comprise the steps: the 1) overcoat of one section umbilical cables of strip off, expose the armouring wire of the inside; 2) weld the screwed connector in some terminations respectively in the steel pipe inner port of cable core; 3) armouring wire that exposes a segment length is passed from the osculum end of push pedal in the termination that will weld the umbilical cables of connector; 4) surround the overcoat of umbilical cables with right cone and left cone, together downwards push in the bellmouth of push pedal together with the cone that right cone and left cone surround umbilical cables; 5) with outer field each the root armouring wire of umbilical cables respectively to turning up; Internal layer armouring wire and cable core together pass the center pit of pressing plate, and the armouring wire that turns up is clamped in the end face that adopts push pedal and the bottom surface of pressing plate and the through hole that passes on the pressing plate through bolt is fixedly connected with screw in the push pedal; 6) again with each root armouring wire of internal layer respectively to turning up, and will be welded on the through hole that connector in the cable core passes the flange center position respectively and connector will be fixed on the flange with nut; 7) the last end face of pressing plate and the bottom surface of flange are clamped internal layer to the armouring wire that turns up, corresponding screw is connected to one on the through hole that passes correspondence on through hole and the flange on the blue dish in counter flange bottom through bolt and the pressing plate; 8) joint use in the test of the umbilical cables after connecting, and passes the blue through hole that coils in counter flange top through bolt and is fixedly attached on the testing apparatus and tests.
The present invention is owing to take above technical scheme; It has the following advantages: 1, the present invention is owing to adopt push pedal and armouring wire and pressing plate and flange that pressing plate is clamped outer upset are clamped the armouring wire of internal layer upset, makes umbilical cables external stability more firm of test.2, the present invention since in the steel pipe port at cable core two ends the some screwed connectors of welding, connector is through the nut joint flange, the influence that makes each unit, inside of umbilical cables not bear tension force and torsion makes test result more true and reliable.3, the present invention protects the overcoat of umbilical cables injury-free owing to the conical sleeve of sheathed one a right cone in the push pedal bellmouth and a left cone composition effectively.4, the present invention is owing to adopt the umbilical cables test to connect umbilical cables with joint; Make inside and outside of this umbilical cables bear pulling force simultaneously; And can afford simultaneously to stretch and reverse, thereby guarantee to go stressed evenly, and be connected with various testing apparatuss easily through crossover sub; Improve the versatility of joint, saved production cost.It can be widely used in the test process of subsea production system umbilical cables.
