Abstract
The invention discloses a petroleum pipeline with taper-shaped joints. The petroleum pipeline comprises a pipeline body. Two end joint positions of the pipeline body are provided with inner taper faces with same taper and same length. The surfaces of the inner taper faces are friction surfaces, and each taper angle of the inner taper faces corresponding to the axis of the pipeline body ranges from 3 to 5 degrees. Two ends of the pipeline body are provided with outer threads respectively. The length of each outer thread is larger than that of the inner taper faces and smaller than 1.2 times of the length of the inner taper faces, so that when the inner taper faces are fitted completely while the outer threads are sufficiently residual, but the length of the outer thread is unsuitable to be too long, or the strength of the petroleum pipeline can be affected. The petroleum pipeline with the taper-shaped joints can be applied to large-size petroleum pipeline structures, joint devices are connected with the inner taper faces with friction faces, stability and tightness of the connection are guaranteed, and stress balance after petroleum pipeline structures are matched can be guaranteed.
Description
Technical field
The present invention relates to a kind of cone-shaped interface petroleum pipeline, belong to the petroleum pipeline technical field.
Background technique
Adopt the petroleum pipeline transfer oil, cost is low, the medium tache less wastage, but to having relatively high expectations of pipeline and pipe joint, so in order to guarantee the stability of petroleum pipeline transfer oil, seal request, structural strength to pipe joint require just to become the important technological problems that a lot of pipe production merchants need solve, and the solution of this problem directly has influence on the great field that oil reserve, oil transportation etc. are related to national economy.So for guarantee oil transportation safe, reduce the wasting phenomena in the course of conveying, the claimant designs the petroleum pipeline interface device of a kind of good stability, good airproof performance, and applying on the same day in the application.In order to match with this petroleum pipeline interface device, also need to design a kind of cone-shaped interface petroleum pipeline.
Summary of the invention
In order to solve the technical problem of petroleum pipeline sealing joint, and the problem of petroleum pipeline interface structure stability, the invention provides a kind of cone-shaped interface petroleum pipeline.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of cone-shaped interface petroleum pipeline, comprise body, it is identical that the two ends interface position of body is respectively equipped with tapering, the inner conical surface of equal in length, the surface of described inner conical surface is friction surface, and described inner conical surface is the 3-5 degree with respect to the angle of the cone angle in body axle center, two ends at described body also are respectively equipped with outside thread, described externally threaded length is greater than the length of described inner conical surface, and less than 1.2 times of the length of described inner conical surface, so that described inner conical surface is when cooperating fully, outside thread has enough surpluses, but described externally threaded length is also unsuitable long, otherwise also can impact the intensity of petroleum pipeline.
The diameter of described petroleum pipeline is 1.5-2m, and wall thickness is 4-6cm.
The externally threaded rotation direction at the two ends of described body is opposite, so that described body can be when reversing, construct simultaneously in two ends, improved efficiency of construction.
A kind of cone-shaped interface petroleum pipeline of the present invention, can be applied in the large scale petroleum pipeline structure, the inner conical surface that employing has friction surface is connected with interface device, guarantees connection stability and sealing, and can guarantee the stress equilibrium after the petroleum pipeline respective outer side edges.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a kind of structural drawing of cone-shaped interface petroleum pipeline.
Among the figure: 1, body; 2, inner conical surface; 3, outside thread.
Embodiment
As shown in Figure 1, the described a kind of cone-shaped interface petroleum pipeline of the embodiment of the invention, comprise body 1, it is identical that the two ends interface position of body is respectively equipped with tapering, the inner conical surface 2 of equal in length, the surface of described inner conical surface 2 is friction surface, and described inner conical surface 2 is the 3-5 degree with respect to the angle of the cone angle in body axle center, two ends at described body 1 also are respectively equipped with outside thread 3, the length of described outside thread 3 is greater than the length of described inner conical surface, and less than 1.2 times of the length of described inner conical surface 2, so that described inner conical surface is when cooperating fully, outside thread has enough surpluses, but described externally threaded length is also unsuitable long, otherwise also can impact the intensity of petroleum pipeline.
The diameter of described petroleum pipeline is 1.5-2m, and wall thickness is 4-6cm.
The externally threaded rotation direction at the two ends of described body is opposite, so that described body can be when reversing, construct simultaneously in two ends, improved efficiency of construction.
A kind of cone-shaped interface petroleum pipeline of the present invention, can be applied in the large scale petroleum pipeline structure, the inner conical surface that employing has friction surface is connected with interface device, guarantees connection stability and sealing, and can guarantee the stress equilibrium after the petroleum pipeline respective outer side edges.
It is to be noted; design of the present invention is not limited only to above embodiment, anyly conceives further improvement and distortion on the basis in the present invention, all should belong to the protection domain of the present invention's design; anyone permits without the obligee, all can not arbitrarily implement the design proposal of this patent.
Claims (2)
1. cone-shaped interface petroleum pipeline, comprise body, it is characterized in that, the two ends interface position of body is respectively equipped with that tapering is identical, the inner conical surface of equal in length, the surface of described inner conical surface is friction surface, and described inner conical surface is the 3-5 degree with respect to the angle of the cone angle in body axle center, also is respectively equipped with outside thread at the two ends of described body, described externally threaded length is greater than the length of described inner conical surface, and less than 1.2 times of the length of described inner conical surface.
