Embodiment 1

[0023] Such as figure 1 As shown, this embodiment provides an anti-corrosion S-shaped pipeline, which includes a plurality of hollow pipes connected in sequence, and each pipe includes a bending part 1 and a fixing part 2 arranged at the openings at both ends of the bending part 1 , the bending portion 1 is a 1 / 4 arc, the fixing portions 2 between adjacent bending portions 1 are fixedly connected by bolts 3 , and a sealing portion 4 is provided between the fixing portions 2 . Each bending part 1 is connected end to end to form a sine wave shape.

[0024] In this embodiment, the fixing part 2 is a flange, and in order to increase the corrosion resistance of the pipeline, an anti-corrosion layer is provided on the inner wall of the pipe fitting. This new type of implementation is set at the front end of the oil pipeline to precipitate barium strontium scale. When the medium passes through the pipeline, it goes through a cycle process of rising-falling-rising-falling-rising. The...

Abstract

The invention provides an anticorrosion S-shaped pipeline. The anticorrosion S-shaped pipeline includes a plurality of hollow structure pipe fittings connected in order, each pipe fitting comprises a bending part and fixed parts arranged at two end openings of the bending part, the fixed parts between adjacent pipe fittings are in bolted connection, seal parts are disposed between the fixed parts, and the inner walls of the pipe fittings are provided with an anticorrosion layer. The anticorrosion S-shaped pipeline provided by the invention is disposed at the front end of an oil pipeline to precipitate barium-strontium scale, greatly reduces the scaling and risk of the oil pipeline, prolongs the service life of the pipeline, also has the characteristics of simple structure and convenient use, and is suitable for oil transportation equipment in the field of chemical industry.

Description

technical field [0001] The invention relates to a pipeline, in particular to an anti-corrosion S-shaped pipeline. Background technique [0002] Oil and gas are transported in oil pipelines. These media contain various impurities, so they are easy to scale. In petroleum engineering, a large number of oil pipelines have scaling phenomena. After the pipeline is scaled, the diameter of the pipeline will shrink and the flow cross-sectional area will become smaller. Cause pressure loss, reduction in displacement and pipeline blockage, scaling can also induce local corrosion of pipelines, lead to pipeline perforation, and cause destructive accidents. Scaling greatly reduces the service life of the pipeline, seriously restricts the normal production of the operation area, and increases the risk of safety and environmental protection. [0003] The replacement of existing oil pipelines is mostly caused by corrosion and scaling. The corrosion of the pipelines is all internal corrosion...
