The standard of pipeline anti-corrosion material is applicable to the equipment of civil and general industrial buildings, the anti-corrosion construction operation of pipelines. A phenomenon of destruction caused by the chemical and electrochemical action of the surrounding medium. According to the corrosion site of the pipe, it can be divided into inner wall corrosion and external wall corrosion, according to the corrosion form of pipe, can be divided into comprehensive corrosion and local corrosion, according to the corrosion mechanism of the pipe, can be divided into chemical corrosion and electrochemical corrosion.
Second, with the development of some pipelines in anti-corrosion also need to keep warm, oil is a complex mixture, corrosion-prone pipeline, anti-corrosion is necessary, but the finished oil pipeline in the case of anti-corrosion needs to do insulation, in the Northeast and winter, hot and cold shrink will freeze and crack pipelines, affecting stable supply.
