Abstract
The utility model relates to a sleeve used in the oil field industrial production, in particular to an end body forming integral type non-coupling sleeve. The end body forming integral type non-coupling sleeve is composed of a sleeve female connector (1), a sleeve main body (3) and a sleeve male connector (4); the end body forming integral type non-coupling sleeve is greatly enhanced in terms of the concentricity, the tensile resistance degree, the sealing performance and the -clipping and blocking prevention, the production cost is saved, the hidden danger of construction is reduced, and the end body forming integral type non-coupling sleeve is suitable for the sleeve raw material bodies with various material, specifications and lengths.
Description
Technical field
The utility model relates to the sleeve pipe that the oil field industrial production is used, especially: a kind of monolithic integral joint casing of end body moulding.
Prior art
At present, the sleeve pipe that the oil field industrial production is used all adopts box cupling to connect, owing to adopt box cupling to connect between many sleeve pipes, many increases much are threaded a little, are increasing more leakage points and bigger hidden danger aspect the sleeve pipe tubing string sealing performance; Especially in the development of production technology, new technology of preparing is extensively used, and the sleeve 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 overlap effective traditional box cupling mode connect after in process of production the shaft bottom meet the card probability that is obstructed and increase, increase on-the-spot operations labor intensity, bring more site operation hidden danger; And better the sleeve pipe product also never occurs.
Summary of the invention
Goal of the invention of the present utility model is the defective that overcomes prior art, and a kind of monolithic integral joint casing of end body moulding is provided; Under the situation that does not increase casing wall thickness, after the cannula tip body partial operation moulding, the sleeve pipe of PROCESS FOR TREATMENT packaged tube body connects male and is connected female with sleeve pipe again, the cancellation casing coupling, realization sleeve pipe monolithic does not have box cupling and connects, and is in full accord through PROCESS FOR TREATMENT rear sleeve end moulding section and sleeve body material; This sleeve pipe has had powerful raising at aspects such as concentricity, tensile strength, sealing performance, anti-sticking deter, saves cost of production, reduces the hidden danger of construction; To achieve these goals, a kind of monolithic integral joint casing of end body moulding, by: sleeve pipe connects female, sleeve body is connected male with sleeve pipe and forms; It is characterized in that: on the sleeve body end, have worker's sleeve pipe to connect male and be connected female with sleeve pipe; The material of sleeve pipe connection male, sleeve pipe connection female and sleeve body is in full accord; Connecting female at sleeve pipe is connected with sleeve pipe on the sleeve body between the male connection transition body is arranged; Wherein: sleeve pipe connection female is connected male with sleeve pipe can be according to using needs to increase length; Sleeve pipe connects female and sleeve pipe connects between the male and can directly connect, and no box cupling connects.A kind of monolithic integral joint casing of end body moulding is according to producing the needs design, process processing is processed into the end moulding section and the sleeve body material is in full accord, connect the cancellation box cupling between the sleeve pipe, therefore this sleeve 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 sleeve 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 casing 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 casing of end body moulding, by: sleeve pipe connect female 1, sleeve body 3 is connected male 4 and forms with sleeve pipe; On sleeve body 3 ends, there is sleeve pipe to connect male 4 and is connected female 1 with sleeve pipe; It is in full accord with the material of sleeve body 3 that sleeve pipe connects male 4, sleeve pipe connects female 1; Connecting female 1 at sleeve pipe is connected with sleeve pipe on the sleeve body 3 between the male 4 connection transition body 2 is arranged; Sleeve pipe connection female 1 is connected male 4 and can prolongs with sleeve pipe; Sleeve pipe connects female 4 and sleeve pipe connects between the male 1 and can directly connect, and no box cupling connects; At first, it is body formed on sleeve body 3 basis to be carried out at its both ends, and the sleeve pipe that formation can increase length as required connects male 4 and is connected female 1 with sleeve pipe; On the sleeve body 3 between sleeve pipe connection female 1 and the sleeve pipe connection male 4, directly process connection transition body 2 again, will connect transition body 2 and be processed into how much external forms of standard; Wherein, sleeve pipe connects between female 4 and the sleeve pipe connection male 1 and can directly connect; No box cupling connects the global formation integral joint casing through processing, modified, alignment, can realize the monolithic integral joint casing of this end body moulding.
Claims (3)
1, a kind of monolithic integral joint casing of end body moulding, by: sleeve pipe connects female (1), sleeve body (3) is connected male (4) and forms with sleeve pipe; It is characterized in that: on sleeve body (3) end, have sleeve pipe to connect male (4) and be connected female (1) with sleeve pipe; It is in full accord with the material of sleeve body (3) that sleeve pipe connects male (4), sleeve pipe connects female (1); Connecting female (1) at sleeve pipe is connected with sleeve pipe on the sleeve body (3) between the male (4) connection transition body (2) is arranged.
