Description
Technical field
The utility model relates to the port plug of pipeline, particularly a kind of heavy caliber tubing and casing explosion bulge test body plug.
Background technology
Petroleum gas is everlasting with tubing and casing and is used under the condition of high temperature, high pressure, in the world pressure energy power in this tubing and casing body anti-is all had corresponding requirement and test method.Tubing and casing production firm make and R﹠D process in, must testing laboratory use explosion bulge test equipment simulate the oil well actual condition and to tubing and casing anti-in the pressure energy masterpiece go out evaluation, draw data-guiding production and R﹠D work.
The application of plug mainly is to be used for occasions such as low-pressure system, finding pass structure, Hardware fitting sealing, be applied in the explosion bulge test of steel pipe high pressure plug seldom.Jap.P. JP08005501A discloses a kind of steel pipe internal pressure test plug, adopts non-electroplating equipment wielding machine formula to connect plug, by screw thread and packoff sealing pipe two ends.This complete equipment is applicable to the internal pressure test of small tubes, but for big caliber pipe, plug is too heavy, and difficulty is installed.And complicated integral structure, operation inconvenience, interchangeability is poor.
The tubing and casing bursting test machine is that a cover is strongly professional, the equipment that working pressure is very high, and pressure will be higher in the about 182Mpa of maximum internal pressure in the API tubing and casing, the thick-walled pipe of the nonstandard design of some specific uses.Therefore have only oil exploitation research institution and oil well pipe manufacturer to be equipped with such equipment.
CNPC's Xi'an tubing explosion bulge test equipment, designed capacity covers tubing and casing and all specifications of line pipe.Weld with the semisphere plug at the pipe two ends, and after the single test, cutting plug can reuse, and the structure of this plug 11 and the tubing and casing of connection 12 thereof are as shown in Figure 1.Although this semicircle plug 11 is stressed more even, processed complex; Be used for the large diameter pipe period of the day from 11 p.m. to 1 a.m and be difficult for the location, the welding difficulty; Plug interchangeability is poor, and the pipe of different size, different wall all will be joined the plug of a corresponding specification; Entery and delivery port 121 is opened on body by the mode of welding, fills with pipe though can guarantee water, and the welding position has become the weak link of a recessiveness, and explosion from here probably causes test failure in the process of boosting; Each test all need hole on body and welded the water-in and water-out joint, processing difficulties, and this contradiction of specification thick-walled pipe is more outstanding greatly.
The bursting test machine set of equipments that Japan's Yamamoto hydraulic pressure industry is developed, the structure of its plug 21 and the tubing and casing of connection 22 thereof are as shown in Figure 2, whole plug 21 is cap-like, radially be provided with a limbers 211 at plug 21, two limberss 212 that are axially arranged with at plug 21 communicate with limbers 211 radially, in order to reduce weight, the plug inboard is groove shape, guarantees that 8-10 that final plug thickness is the pipe wall thickness doubly.After the single test, cutting plug can reuse, and test specification covers 2 3/8 " 5 but also 1/2 " tubing and casing not only.Find that in process of the test also there are a lot of deficiencies in this plug of Japan: the test pipe of each specification wall thickness of the first all will have the plug of a corresponding specification to be complementary, and interchangeability is poor; It two is that water injection hole has only one, and according to standard-required, the length L of test pipe must not be less than 10 times of pipe diameter.For tubule footpath oil pipe, the test pipe is shorter, and by a water injection hole water filling, the time of fills with water can be not oversize yet, as 2 and 7/8 " pipe probably only need 15～20 minutes." sleeve pipe has increased to 3m according to the requirement of caliber developmental tube length, and by a water injection hole water filling, efficient sharply reduces, and needs more than 30 hours, and the test period is oversize but when experimental sample tube is the heavy caliber sleeve pipe, as 20.
