Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0012] like figure 1 and 2 The shown pipeline for oil transportation is in the shape of a straight pipe. The inner wall of the pipeline 1 is provided with two flow guide ribs 2 arranged opposite to each other in the axial direction. On the inner wall, the pitch L of the helix is ​​twice the inner diameter of the pipe 1 . When the oil is transported in the pipeline 1, it will flow along the spiral channel provided by the guide rib 2 and the center of the pipeline 1. Since the pipe wall is a spiral channel, the flowing oil generates a circumferential tangential force on the pipe wall, reducing Adhesion occurs on the pipe wall, resulting in blockage.

[0013] The diversion ribs 2 and the inner wall of the pipeline 1...

Abstract

The invention discloses a pipeline. The pipeline is a straight pipe, wherein two flow-guiding ribs which face each other are arranged on the inner wall of the pipeline along the axial direction; the flow-guiding ribs are spirally arranged on the inner wall of the pipeline; and the screw pitch of helixes is two times the inner diameter of the pipeline. Due to the fact that the flow-guiding ribs are arranged on the inner wall of the pipeline, the pipeline is simple in structure and plays a flow-guiding effect on petroleum transmission; due to the fact that the flow-guiding ribs are spirally arranged, flowing petroleum does not retain and stick, the petroleum is convenient to deliver, and the effect is good.

Description

technical field [0001] The invention relates to the technical field of petroleum transportation devices, in particular to a pipeline for petroleum transportation. Background technique [0002] After oil extraction, it must be transported to the corresponding processing department in order to be better utilized, and the pipeline for transporting oil is an indispensable equipment. The existing oil pipeline is a straight pipe structure, and because the oil itself is viscous, it is easy to stick to the pipe wall, causing blockage and bringing inconvenience to oil transportation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a pipeline, which is convenient for oil transportation and not easy to be blocked. [0004] In order to achieve the purpose of the above invention, the present invention provides the following technical solutions: a pipe, which is in the shape of a straight pipe, and the inner wall of the pipe is pro...
