Abstract
The invention belongs to the petroleum pipeline technical field, and especially relates to a special thread direct connection type large diameter oil pipe sleeve comprising an oil conveying pipe and an oil pipe connecting sleeve; two ends of the oil conveying pipe are processed with outer threads matched with inner thread of the oil pipe connecting sleeve; the thread can be double-teeth or triple-teeth thread, each thread pitch cycle is 8.466 mm in length, and tooth height is 1.982mm; each thread pitch cycle comprises a tooth top and a tooth bottom, and both of which are 4.233 mm in length; in order to improve screwing speed, the lean angle on the tooth bottom of the outer thread on two ends of the oil conveying pipe in a screwing direction is designed to be 30 degrees, and the corresponding opposite direction angle is designed to be 3 degrees; the special thread direct connection type large diameter oil pipe sleeve is simple in structure, reasonable in design, and can effectively improve thread connection screwing speed and intensity.
Description
Technical field
The invention belongs to petroleum pipeline technical field, particularly relate to a kind of special thread direct-connected heavy caliber oil pipe cover.
Background technology
At existing petroleum pipeline tie point place, the mode usually using pipe ends to weld realizes the connection between petroleum pipeline, but existing pipeline connected mode also exists drawback, when existing pipeline connects, by the pipeline enclosure poor toughness be welded and fixed, use for a long time or when a certain section of pipeline breaks down, be inconvenient to keep in repair, moreover, when existing pipeline connects, efficiency is poor, and speed is slow, do not meet petroleum pipeline installation rate when going into the well fast, the basic norm that installation accuracy is high.
In recent years, occurred screw connected connected pipes on the market, but the Design of Screw Thread of existing connected pipes is unreasonable, when oil pipe is connected and fixed, oil pipe adapter sleeve is connected speed with the screw thread of oil pipe slow, and after connecting, between oil pipe, fastness is poor.
As the technician of the industry, be necessary very much to integrate existing oil pipe cover link technique, design a kind of special thread direct-connected heavy caliber oil pipe cover, realize the speed that spins between petroleum pipeline and oil pipe adapter sleeve fast, twist and connect the high advantage of rear intensity.
Summary of the invention
For realizing above-described technical functionality, special thread provided by the invention direct-connected heavy caliber oil pipe cover, its technical scheme is as follows: it is made up of two parts, and be respectively petroleum pipeline and oil pipe adapter sleeve, the two ends of described petroleum pipeline are processed with screw thread; The two ends, inside of oil pipe adapter sleeve are processed with the screw thread be connected with petroleum pipeline.
Described oil pipe adapter sleeve is internal thread, the two ends of petroleum pipeline are processed with the external screw thread matched with the internal thread of oil pipe adapter sleeve, described screw thread can be two pitch threads or three pitch threads, and the length in each pitch cycle of described screw thread is 8.466 millimeters, and tooth is high is 1.982 millimeters; Comprise at the bottom of a crest and a tooth in each pitch cycle, described crest and the length at the bottom of tooth are all 4.233 millimeters, of the present inventionly speed is screwed for improving, the angle of inclination screwed on direction of the external screw thread tooth bottom, two ends of petroleum pipeline is designed to 30 degree, is 3 degree by opposite direction angle design corresponding thereto.
The screw thread that the two ends of described petroleum pipeline and the two ends of oil pipe adapter sleeve inside process matches, at the bottom of the two ends external screw thread tooth of petroleum pipeline and the angle at the bottom of the angle at crest place and the internal thread tooth of oil pipe adapter sleeve and crest place identical.
Beneficial effect of the present invention: structure of the present invention is simple, reasonable in design, by the two ends threading by petroleum pipeline; The two ends, inside of oil pipe adapter sleeve are processed with the internal thread be connected with petroleum pipeline, again the angle of inclination screwed on direction at screw thread place is designed to 30 degree, it is 3 degree by opposite direction angle design corresponding thereto, and whole screw thread is two pitch threads or three pitch threads, effectively raises the speed that screws that is threaded and screw intensity.

Fig. 4 is external thread structure schematic diagram of the present invention.
In accompanying drawing: 1, petroleum pipeline, 11, external screw thread, 2, oil pipe adapter sleeve, 21, internal thread, 3, at the bottom of tooth, 4, crest.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.As shown in drawings, the RT-TS-3 special thread taking charge of setting research and development for me is described further the present invention, and the present invention is made up of two parts, is respectively petroleum pipeline 1 and oil pipe adapter sleeve 2, and the two ends of described petroleum pipeline 1 are processed with screw thread; The two ends, inside of oil pipe adapter sleeve 2 are processed with the screw thread be connected with petroleum pipeline 1.
Described oil pipe adapter sleeve 2 is internal thread 21, the two ends of petroleum pipeline 1 are processed with the external screw thread 11 matched with the internal thread 21 of oil pipe adapter sleeve 2, described screw thread can be two pitch threads or three pitch threads, as shown in drawings, the length B in each pitch cycle of described internal thread is 8.466 millimeters, and tooth height G is 1.982 millimeters; D at the bottom of a crest C and tooth is comprised in each pitch cycle, at the bottom of described crest C and tooth, the length of D is all 4.233 millimeters, of the present inventionly speed is screwed for improving, the angle of inclination A screwed on direction of the two ends external screw thread 11 tooth bottom of petroleum pipeline 1 is designed to 30 degree, opposite direction angle E is corresponding thereto designed to 3 degree.
The screw thread that the two ends of described petroleum pipeline 1 and the two ends of oil pipe adapter sleeve 2 inside process matches, at the bottom of two ends external screw thread 11 tooth of petroleum pipeline 1 and the angle at the bottom of the angle at crest place and internal thread 21 tooth of oil pipe adapter sleeve 2 and crest place identical, the length B1 in its each pitch cycle is 8.466 millimeters, tooth height G1 is 1.982 millimeters, at the bottom of crest C1 and tooth, the length of D1 is all 4.233 millimeters, the angle of inclination A1 screwed on direction of tooth bottom is designed to 30 degree, and opposite direction angle E1 is corresponding thereto designed to 3 degree.
Structure of the present invention is simple, reasonable in design, by the two ends threading 11 by petroleum pipeline 1; The two ends, inside of oil pipe adapter sleeve 2 are processed with the internal thread 21 be connected with petroleum pipeline, again the angle of inclination screwed on direction at screw thread place is designed to 30 degree, when screwing, inclined-plane cooperation is more prone to and connects more smooth and easy, it is 3 degree by opposite direction angle design corresponding thereto, intensity after screwing effectively is improved, and whole screw thread is two pitch threads or three pitch threads, effectively raise especially be threaded screw speed.
