Abstract
The utility model discloses a petroleum pipeline with conical connectors. The petroleum pipeline with the conical connectors comprises a body. The connectors at the two ends of the body are provided with inner conical surfaces which are identical in conicity and length respectively. The surface of each inner conical surface is a friction surface, and the cone angle of the inner conical surface relative to the axis of the body ranges from 3 to 5 degrees. External threads are further arranged at the two ends of the body respectively. The length of the outer external threads is greater than that of the inner conical surfaces and smaller than 1.2 times that of the inner conical surfaces, and therefore the outer external threads can have enough allowance when the inner conical surfaces are completely matched; however, the external threads should not be too long, otherwise, the strength of the petroleum pipeline will be affected. The petroleum pipeline with the conical connectors can be applied to a large-size petroleum pipeline structure; the inner conical surfaces with the friction surfaces are used for being connected with connector devices, therefore, the stability and airtightness of the connection are ensured, and the balanced stress of the petroleum pipeline structure after matching can be ensured.
Description
Technical field
The utility model relates to a kind of cone-shaped interface petroleum pipeline, belongs to the petroleum pipeline technical field.
Background technique
Adopt the petroleum pipeline transfer oil, cost is low, the medium tache waste is few, 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 business need to solve, and this solution of problem directly has influence on the major areas that oil reserve, oil transportation etc. are related to national economy.So for guarantee oil transportation safe, reduce the wasting phenomena in 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.
The model utility content
In order to solve the technical problem of petroleum pipeline sealing joint, and the problem of petroleum pipeline interface structure stability, the utility model provides a kind of cone-shaped interface petroleum pipeline.
The purpose of this utility model 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, inner conical surface 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 coordinating fully, outside thread has enough surpluses, but described externally threaded length is also unsuitable long, otherwise the intensity to petroleum pipeline also can impact.
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, constructing simultaneously in two ends, has improved efficiency of construction.
A kind of cone-shaped interface petroleum pipeline described in the utility model, can be applied in large scale petroleum pipeline structure, the inner conical surface that employing has friction surface is connected with interface device, guarantees stability and the sealing of connection, and can guarantee the stress equilibrium after the petroleum pipeline respective outer side edges.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is a kind of structural drawing of cone-shaped interface petroleum pipeline.
In 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 utility model embodiment, comprise body 1, it is identical that the two ends interface position of body is respectively equipped with tapering, inner conical surface 2 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 coordinating fully, outside thread has enough surpluses, but described externally threaded length is also unsuitable long, otherwise the intensity to petroleum pipeline also can impact.
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, constructing simultaneously in two ends, has improved efficiency of construction.
A kind of cone-shaped interface petroleum pipeline described in the utility model, can be applied in large scale petroleum pipeline structure, the inner conical surface that employing has friction surface is connected with interface device, guarantees stability and the sealing of connection, and can guarantee the stress equilibrium after the petroleum pipeline respective outer side edges.
It is to be noted; design of the present utility model is not limited only to above embodiment; any further improvement and distortion on the utility model design basis; the protection domain that all should belong to the utility model design; anyone permits without the obligee, all can not arbitrarily implement the design proposal of this patent.
Claims (2)
