Abstract
The utility model relates to an oil pipe used in industry manufacture of the oil field, in particular to an integral non-coupling oil pipe with end body forming, which is composed of a connecting male head (1), an oil body (2) and an oil pipe connecting female head (4), wherein the integral non-coupling oil pipe with end body forming is designed according to the manufacturing requirements, the material quality of the end forming portions is completely corresponding with that of the oil pipe body after being processed, couplings of the connections between oil pipes are saved, and the concentricity, the stretch-proofing intensity, the sealing performance, the anti-seizing, the clog-proof performance and the like of the oil pipes are greatly improved, the manufacturing cost is reduced, the hidden danger of the construction is reduced, and the oil pipe is suitable for oil pipe raw material bodies with various material qualities, various specifications and various lengths.
Description
Technical field
The utility model relates to the oil pipe that the oil field industrial production is used, especially: a kind of monolithic integral joint tubing of end body moulding.
Prior art
At present, the oil pipe that the oil field industrial production is used all adopts box cupling to connect, owing to adopt box cupling to connect between the multiple-tubing string, many increases much are threaded a little, are increasing more leakage points and bigger hidden danger aspect the oil pipe tubing string sealing performance; Especially in the development of production technology, different oil production methods are used, and the oil pipe that adopts traditional box cupling mode to connect all is difficult to meet the needs of production at aspects such as hot strength, sealing performance, safe construction, saving costs; And oil pipe is met the card probability that is obstructed easily and is increased in the shaft bottom after connecting through traditional box cupling mode, increases the labour intensity of field operation, brings more site operation hidden danger; And better tubing product also never occurs.
Summary of the invention
The goal of the invention of the monolithic integral joint tubing of a kind of end body moulding of the utility model is: the monolithic integral joint tubing that a kind of end body moulding is provided, after making oil pipe end body partial operation moulding under the situation that does not increase the oil pipe wall thickness, PROCESS FOR TREATMENT becomes the oil pipe connection male of oil pipe body to be connected female with oil pipe again, the cancellation tubing coupling, realization oil pipe monolithic does not have box cupling and connects, and is in full accord through special process processing rearward end moulding section and oil pipe body material; This oil pipe has had powerful raising in concentricity, tensile strength, sealing performance etc., saves cost of production, reduces the hidden danger of construction; To achieve these goals, the monolithic integral joint tubing of a kind of end body moulding of the utility model is achieved in that a kind of monolithic integral joint tubing of end body moulding, by: oil pipe connects male, the oil pipe body is connected female with oil pipe and forms; It is characterized in that: it is that one is processed to form on the oil pipe body that oil pipe connection female, oil pipe connect male, and the material of oil pipe connection female, oil pipe connection male and oil pipe body is in full accord, makes directly no box cupling connection between the oil pipe; On the oil pipe body between oil pipe connection female and the oil pipe connection male, directly be processed with connection transition body, be convenient to the work lifting; Wherein, oil pipe connects male, oil pipe connects female can increase length as required, so that the repeatedly reparation of monolithic integral joint tubing and recycling.A kind of monolithic integral joint tubing of end body moulding is according to producing the needs design, in full accord through processing processing rearward end moulding section and oil pipe body material, connect the cancellation box cupling between the oil pipe, this oil pipe has had powerful raising at aspects such as concentricity, tensile strength, sealing performance, anti-sticking deter, save cost of production, reduce the hidden danger of construction; Be applicable to the oil pipe raw bodies of various materials, all size, all lengths.
Description of drawings
Accompanying drawing is a kind of half sectional view of monolithic integral joint tubing of end body moulding.
The specific embodiment
Below with reference to the accompanying drawings (as shown in the figure) the utility model is described further: a kind of monolithic integral joint tubing of end body moulding, by: oil pipe connect male 1, oil pipe body 2 is connected female 4 and forms with oil pipe; At first according to the oil pipe body 2 of producing needs design unlike material, specification, length, it is body formed on oil pipe body 2 basis to be carried out at its both ends, form oil pipe connection male 1 and be connected female 4 with oil pipe, in full accord through processing processing rearward end moulding section and oil pipe body 2 materials; Between oil pipe connection female 4 and oil pipe body 2, directly be processed with connection transition body 3 again, make oil pipe connect male 1 and be connected female 4 with oil pipe, be processed into the geometry external form of standard at last, be convenient to produce lifting respectively at the two ends of oil pipe body 2; Wherein, oil pipe connect female 4 is connected male 1 with oil pipe can be according to using needs increase length so that the repeatedly reparation of monolithic integral joint tubing and recycling.
Claims (2)
1, a kind of monolithic integral joint tubing of end body moulding, by: oil pipe connects male (1), oil pipe body (2) is connected female (4) and forms with oil pipe; It is characterized in that: oil pipe connects female (4), oil pipe connection male (1) is to go up one at oil pipe body (2) to be processed to form, and oil pipe connection female (4) is connected male (1) with oil pipe in full accord with the material of oil pipe body (2); On the oil pipe body (2) between oil pipe connection female (4) and the oil pipe connection male (1), directly be processed with and connect the transition body.
2, the monolithic integral joint tubing of a kind of end body moulding according to claim 1 is characterized in that: the oil pipe of multiple-tubing string connects between female (4) and the oil pipe connection male (1) and connects for direct, and no box cupling connects.
