Efficient heat-preservation oil delivering pipeline

Abstract

The invention discloses an efficient heat-preservation oil delivering pipeline comprising an inner pipeline body and an outer pipe pipeline body. A heat-preservation layer, an anti-corrosion layer anda waterproof layer are arranged between the inner pipeline body and the outer pipe pipeline body. A plurality of heat-preservation pipes are arranged in the heat-preservation layer; the exteriors ofthe heat-preservation pipes in the heat-preservation layer are filled with glass cotton; a partition plate is arranged in each heat-preservation pipe and divides the heat-preservation pipe into two cavities; the cavities close to the inner pipeline body are filled with foam; and the cavities away from the inner pipeline body are filled with desiccants. Heating wires are wound on the outer walls ofthe heat-preservation pipes. Sawteeth of the waterproof layer and the anti-corrosion layer are mutually embedded. Delivering hanging blocks are arranged on the two sides of the outer pipe pipeline body, and clamping grooves are formed in the bottom faces of the delivering hanging blocks. According to the efficient heat-preservation oil delivering pipeline, through the special structure, the pipeline has good heat-preservation performance, oil blockage can be avoided, the convenience of oil delivering is improved, the stability of the oil pipeline structure is enhanced, and the anti-corrosionlayer and the waterproof layer are arranged, so that the anti-corrosion and waterproof performance of the pipeline is greatly improved, and carrying and mounting are facilitated.

Description

Technical field [0001] The invention relates to a petroleum pipeline, in particular to an efficient thermal insulation petroleum transportation pipeline. 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 difficul...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing existing oil pipeline usually uses the insulation layer to reduce the heat loss of the oil in the pipeline in order to keep it warm. , and there is air between the insulation layer and the inner cylinder, the insulation effect is not good
