Abstract
The utility model relates to a petroleum pipe, in particular to a clamp-sticking-resisting oil pipe with lengthened and thickened ends. The technical scheme is that the oil pipe comprises an oil pipe body and is characterized in that two ends of the body are connected with the thickened ends, the outer diameter D4 of the thickened ends meets requirements of API5CT, and the length of the thickened ends is within the length twice of the Leu maximum length specified in the API5CT. The clamp-sticking-resisting oil pipe with the lengthened and thickened ends is applicable to machining of the thickened oil pipe with the diameters of 26.67, 33.4, 42.16, 48.26, 60.3, 73.02, 88.9, 101.6 and 114.3. The clamp-sticking-resisting oil pipe with the lengthened and thickened ends has the advantages of being simple and reasonable in structure, safe and convenient to use, capable of increasing repairing and clamping times of the oil pipe.
Description
Technical field
The utility model relates to a kind of petroleum oil, is specifically related to the anti-stick button oil pipe of a kind of end lengthening thickening.
Background technology
In the oil development process, oil pipe will be recycled, but because oil pipe upset end size is limited, and last shackle number of times is more, is prone to thread gluing, and heavy wall tubing can't be repaired again because of upset end size reason and scrap, and causes the serious wasting of resources.The present invention breaks through API thickening size, end-thickened design length, repairs number of times to increase oil pipe to the full extent.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art, provides a kind of end lengthening simple in structure, with low cost, long service life to thicken anti-stick button oil pipe.
Its technical scheme is: the body two ends connect thickened end, and said thickened end D outer diameter 4 meets API 5CT requirement, and thickened end length is in 2 times of Leu (the heavy wall tubing pipe end begins to reduce director's degree to the thickening thickness) maximum length of API 5CT regulation; Below be the relevant parameter of the oil pipe stipulated among the API 5CT:
Such scheme is broken through the notion of API thickening size, develops the special upset size.Oil pipe according to different specifications; Continue to optimize the thickening size; Develop special lengthening oil pipe; Increase to the full extent and repair the button number of times, the utility model is applicable to the processing of Φ 26.67, Φ 33.4, Φ 42.16, Φ 48.26, Φ 60.3, Φ 73.02, Φ 88.9, Φ 101.6, Φ 114.3 heavy wall tubings.Its advantage is: simple and reasonable for structure, safe and convenient to use, and can effectively play repairing of oil pipe of increase and buckle number of times.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, oil pipe body, 2, thickened end.
The specific embodiment
Be described in detail the embodiment of the utility model below in conjunction with accompanying drawing: the special lengthening oil pipe in end, the two ends of oil pipe body 1 extend to thicken and handle, and form thickened end 2, and carry out the novel special anti-stick oil pipe that local special thermal treatment is developed.Carry out end lengthening, thickening processing according to the scheme of following form, this type oil pipe is repaired number of times with screw thread and is brought up to 4～5 times, and last shackle number of times is brought up to more than 15 times, has improved the service efficiency of heavy wall tubing greatly.
Concrete for example such as the heavy wall tubings that extend for Φ 60.3: the present invention designs thickening length range: 101.6～202mm, thickening diameter of phi 65.89～67.48mm.And API 5CT regulation thickening length≤76.2～101.6mm, thickening diameter of phi 65.89～67.48mm.
