A transportation pipeline used in the chemical industry

Abstract

The invention discloses a transportation pipeline for the chemical industry. The transportation pipeline comprises a pipeline body and flanges, wherein the flanges are arranged at the two ends of the pipeline body. A rustproof layer is arranged on the outer layer of the pipeline body, anticorrosion layers are arranged inside the pipeline body and outside the flanges, the thickness of the rustproof layer is 1-3mm, and the thickness of the anticorrosion layers is 3-8mm. By improving the machining method, the machined pipe fitting is attractive in appearance, the interior of the machined pipe fitting is resistant to corrosion and pressure, and the outer layer of the machined pipe fitting is fireproof, waterproof and rustproof; the pipe fitting is long in service life, convenient to connect, safe in use and free from environment pollution; in addition, improvement can be carried out in existing manufacturers, equipment does not need to be added, and therefore the transportation pipeline for the chemical industry is economical, practical, high in popularization and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of pipeline processing, and in particular relates to a transportation pipeline used in the chemical industry. Background technique [0002] With the continuous and rapid development of my country's economy, the petroleum and chemical industries have gradually become the pillar industries of our country. In the petroleum and chemical industries, a large number of pipelines are needed to transport various finished products, waste liquids, and gases. The pipeline anticorrosion is divided into internal anticorrosion Compared with external anti-corrosion, there are many domestic pipeline anti-corrosion enterprises, and there are many anti-corrosion methods, but the overall quality is not good, the service life of the pipeline is short, and the emphasis is placed on internal anti-corrosion, and external anti-corrosion is not paid much attention to, especially the fire protection of the outer layer of the pipeline.

[0002] With the continuous and rapid development of my country's economy, the petroleum and chemical industries have gradually become the pillar industries of our country. In the petroleum and chemical industries, a large number of pipelines are needed to transport various finished products, waste liquids, and gases. The pipeline anticorrosion is divided into internal anticorrosion Compared with external anti-corrosion, there are many domestic pipeline anti-corrosion enterprises, and there are many anti-corrosion methods, but the overall quality is not good, the service life of the pipeline is short, and the emphasis is placed on internal anti-corrosion, and external anti-corrosion is not paid much attention to, especially the fire protection of the outer layer of the pipeline. Steel components do not need fire protection, but once the pipeline is baked at high temperature, the performance of the steel component will decline, which will directly lead to the collapse of the pipeline, seriously threatening the safety of people and equipment
