Embodiment Construction

[0014] Such as Figure 1-2 As shown, a high-pressure delivery pipeline described in the embodiment of the present invention includes a body 1, which is in the shape of a round tube. Concave round table 3, the radial width of the inner concave round table 3 is equal to the wall thickness of the middle part of the body, and external threads are provided on the thickened outer walls 2 at both ends of the body 1, and the thickness of the thickened outer wall 2 of the body 1 is the same as that of the middle part of the body more than twice the wall thickness.

[0015] The axial width of the concave circular table is more than twice the thickness of the thickened outer wall, and the axial width of the concave circular table is less than the length of the external thread of the thickened outer wall, so as to ensure that the concave circular table has enough space to accommodate the seal Pad and pipe construction.

[0016] The length of the external thread is less than the length o...

Abstract

The invention discloses a high-pressure delivery pipeline which comprises a tubular body. Thickened outer walls are arranged at two ends of the body, concave circular truncated cones are respectively arranged on inner walls of the two ends of the body, the radial width of each concave circular truncated cone is equal to the wall thickness of the middle of the body, external threads are arranged on the thickened outer walls at the two ends of the body, and the thickness of each thickened outer wall of the body is larger than two times the wall thickness of the middle of the body. The axial width of each concave circular truncated cone is larger than two times the thickness of each thickened outer wall and is smaller than the total length of the external threads of each thickened outer wall, so that space of the concave circular truncated cones is assuredly sufficient for accommodating sealing pads and a pipeline structure. The high-pressure delivery pipeline has the advantages that sufficient pressure bearing capacity of the ends of the pipeline is guaranteed by the thickened outer walls; the concave circular truncated cones are connected with corresponding pipelines, so that sealing is facilitated, bearing pressure is transferred to the corresponding pipelines, and the sealing pads do not need to bear the pressure.

Description

technical field [0001] The invention relates to a high-pressure transmission pipeline, which belongs to the technical field of high-pressure transmission petroleum 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 ...
