Embodiment Construction

[0014] Such as Figure 1-2 As shown, an embedded high-pressure petroleum pipeline described in the embodiment of the present invention includes a body 1, which is in the shape of a round tube. Both ends of the body 1 have thickened outer walls 2. A circumscribed groove 3 is provided, the inner wall of the circumscribed groove is smooth, the cross section of the circumscribed groove 3 is a rectangular structure, and the circumscribed groove 3 is located in the middle of the outer end surface of the thickened outer wall, and The thickened outer walls at both ends of the body are provided with external threads, and the thickness of the thickened outer walls of the body 1 is greater than that of the middle part of the body.

[0015] The radial width of the circumscribed groove 3 is one third of the thickness of the thickened outer wall.

[0016] The length of the external thread is less than the length of the thickened outer wall.

[0017] In the embedded high-pressure oil pipel...

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 [0001] The invention relates to an embedded high-pressure oil pipeline, which belongs to the technical field of high-pressure oil pipelines. Background technique [0002] The sealing problem after the oil pipeline is docked is a very important problem. In the prior art, flange joints are often used for connection and sealing. The tensile force transmitted to the flange is also easy to cause damage to the flange, so the requirements for the flange are relatively high. At the same time, due to the long-term high stress, the flange and the bolts used to connect the flange will inevitably produce fatigue stress after a period of use, so the longer the use time, the easier it is to be damaged. [0003] At the same time, due to the high-pressure and high-speed transportation of oil pipelines, the sealing performance of pipelines under high-pressure environments is also a technical problem faced by the existing technology. The use of conventional flange connections...
