Petroleum pipeline facilitating transportation and hoisting

Abstract

The invention discloses a petroleum pipeline facilitating transportation and hoisting. The petroleum pipeline comprises an inner pipeline and an outer pipeline arranged outside the inner pipeline in asleeving mode, wherein a heat preservation layer is arranged outside the inner pipeline, circular arc shaped reinforcing plates are arranged between the adjacent outer walls of two 3 / 4 round pipes inthe heat preservation layer, an anticorrosive coating is arranged between the heat preservation layer and the outer pipeline, a filter screen is arranged at the missing part of each 3 / 4 round pipe, the outer wall of the outer pipeline is sleeved with multiple pairs of fixing clamp rings, and multiple clamping blocks are arranged on the adjacent end faces of the two fixing clamp rings in the circumference direction. The petroleum pipeline has good heat preservation performance through the special structure and can avoid petroleum blockage, the special shape of the pipeline increases the contact area between petroleum and a pipe wall in the transportation process, the petroleum can constantly collide in the movement process, and thus the liquidity during transportation is improved. In addition, the petroleum pipeline is provided with the anticorrosive coating, and the anticorrosive performance of the pipeline is greatly improved.

Description

Technical field [0001] The invention relates to a petroleum pipeline, in particular to a petroleum pipeline that is convenient for transportation and lifting. Background technique [0002] Petroleum, one of the main targets of geological prospecting, is a viscous, dark brown liquid called "the blood of industry". There is oil storage in parts of the upper crust. The main component is a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons. After oil is extracted, it must be transported to the corresponding processing department in order to be better utilized. Among them, the oil pipeline to transport oil is an indispensable equipment. In the process of oil extraction, due to the high wax content of the oil and the high oil concentration, the oil pipeline is often difficult to transport. Especially in the cold season, the flow resistance of the oil in the oil pipeline will increase significantly. Heat up or increase the delivery pressure to solve the problem of dif...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing petroleum pipeline usually utilizes the thermal insulation layer to reduce the loss of oil heat in the pipeline in order to keep it warm. However, it has some deficiencies. There is air between the layer and the inner cylinder, and its insulation effect is not good
