Abstract
The invention discloses an embedded high-pressure petroleum delivering pipeline which comprises a tubular body with two ends provided with thickening outer walls. Annular grooves are formed on the outer end face of each thickening outer wall, the inner wall of each annular groove is smooth, the cross section of each annular groove is of a rectangular structure, the annular grooves are positioned in the middles of the outer end faces of the thickening outer walls, external threads are arranged on the thickening outer walls at the two ends of the body, and the thickness of each thickening outer wall of the body is larger than that of the wall in the middle of the body. The annular grooves are convenient for mounting of sealing rings, big pressure can be borne, outward expanding of the sealing rings under a pressure-bearing environment can be prevented, oxidation speed of the sealing rings inside the annular grooves can be decreased, and the service life of the petroleum pipeline can be prolonged.
Description
Technical field
The present invention relates to a kind of embedded high-pressure delivery petroleum pipeline, belong to high-pressure delivery petroleum pipeline technical field.
Background technique
Sealing problem after the petroleum pipeline butt joint is a very important problem, prior art is often used flange-interface to connect and is sealed, its structure is comparatively complicated, and the pulling force that bolt bears in the process of flange-interface sealing is bigger, the pulling force that bolt bears is delivered on the flange, also easily flange is brought damage, thus to the requirement of flange than higher.Simultaneously, owing to bear big stress effect for a long time, the bolt that flange and adpting flange are used will inevitably produce the fatigue stress phenomenon after using a period of time, so service time, more easy appearance more of a specified duration damaged.
Simultaneously, because petroleum pipeline is in high pressure, the process of carrying at a high speed, the sealing under the pipeline hyperbaric environment also is the technical problem that prior art faces, and adopts conventional flange to connect and can not satisfy the high pressure that increases day by day, the requirement of carrying at a high speed.
Summary of the invention
In order to solve the excessive technical problem of pipe end constructions seal structure complex, stress of petroleum pipeline, the invention provides a kind of embedded high-pressure delivery petroleum pipeline.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of embedded high-pressure delivery petroleum pipeline, comprise body, body is cylindrical, the two ends of body have the thickening outer wall, are provided with the ring cutting groove, the inner wall smooth of described ring cutting groove in the exterior edge face of thickening outer wall, the transverse section of described ring cutting groove is rectangular configuration, described ring cutting groove is positioned at the middle part of exterior edge face of thickening outer wall, and is provided with outside thread at the thickening outer wall at the two ends of body, and the thickness of the thickening outer wall of body is greater than the wall thickness at body middle part.
The radial width of described ring cutting groove be described thickening outer wall thickness 1/3rd.
Described externally threaded length is less than the length of thickening outer wall.
A kind of embedded high-pressure delivery petroleum pipeline of the present invention, the ring cutting groove is convenient to install seal ring, can bear bigger pressure, and can prevent that seal ring from expanding outwardly under the pressure-bearing environment, and can reduce the oxidation rate of the seal ring of ring cutting inside grooves, prolong the working life of petroleum pipeline.
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 embedded high-pressure delivery petroleum pipeline.
Fig. 2 is use view of the present invention.
Among the figure: 1, body; 2, thickening outer wall; 3, ring cutting groove.
Embodiment
Shown in Fig. 1-2, the described a kind of embedded high-pressure delivery petroleum pipeline of the embodiment of the invention, comprise body 1, body 1 is cylindrical, the two ends of body 1 have thickening outer wall 2, exterior edge face at thickening outer wall 2 is provided with ring cutting groove 3, the inner wall smooth of described ring cutting groove, the transverse section of described ring cutting groove 3 is rectangular configuration, described ring cutting groove 3 is positioned at the middle part of the exterior edge face of thickening outer wall, and the thickening outer wall at the two ends of body is provided with outside thread, and the thickness of the thickening outer wall of body 1 is greater than the wall thickness at body middle part.
The radial width of described ring cutting groove 3 be described thickening outer wall thickness 1/3rd.
Described externally threaded length is less than the length of thickening outer wall.
A kind of embedded high-pressure delivery petroleum pipeline of the present invention, the ring cutting groove is convenient to install seal ring, can bear bigger pressure, and can prevent that seal ring from expanding outwardly under the pressure-bearing environment, and can reduce the oxidation rate of the seal ring of ring cutting inside grooves, prolong the working life of petroleum pipeline.
