Abstract

The invention relates to an oil delivery pipe structure containing high polymer materials, in particular to a fuel-resistant anti-static oil delivery pipe. A pipeline of the fuel-resistant anti-static oil delivery pipe is divided into three layers sequentially including a reinforced layer, an adhesive layer and a fuel-resistant anti-static layer from outside to inside; the reinforced layer is a high polymer material, and the fuel-resistant anti-static layer is a fuel-resistant anti-static high polymer material. The fuel-resistant anti-static oil delivery pipe disclosed by the invention has fuel-resistant and anti-static functions, and is simple in manufacturing process.

Description

technical field [0001] The invention relates to an oil pipeline structure comprising a polymer composite material, in particular to a fuel-resistant and anti-static oil pipeline. Background technique [0002] Metal pipes used in traditional gas stations are prone to corrosion and damage, causing gasoline leakage and polluting the environment and groundwater. With the continuous improvement of environmental protection requirements, it is the general trend that metal oil pipelines are replaced by plastic oil pipelines. The plastic piping system has the characteristics of being cleaner, safer, stronger and more convenient. Its application in the construction of gas stations is the general trend and has been gradually developed. . Most of the existing plastic pipe manufacturers focus on water supply pipes, and the targeted oil and gas pipe market is still immature, especially the research on fuel-resistant and anti-static oil pipeline technology is relatively small. [0003] ...
