委内瑞拉某石油公司为提高石油采收率。正在开发一项高压气体汪入项目。该项目旨在将压缩厂的气体压力由1200lb／in2提高到9000lb／in2，再将其输向注入井，如此高气压和高温（90℃），公司选择了壁厚2.5in的API5L-X60碳素钢管作为输气管。管线采用了双层熔结环氧涂层，接头处使用高温热收缩套。涂层选择中所考虑的几个参数为:高温、壁厚、施工条件、焊接过程中的热控制及实验室中的涂层特性。涂层评估采用的是一个经特定设计的高温试验。实验室结果（抗冲击、固化度、阴极剥离、附着力、热水浸泡）表明；所用施工条件满足项目的技术要求。
A Venezuelan oil company to increase oil recovery. A high pressure gas project is under development. The project aims to increase the gas pressure in the compression plant from 1200 lb / in2 to 9,000 lb / in2 and to the injection well at such high pressures and temperatures (90 ° C) that the company chose the API5L-X60 carbon Prime steel pipe as a gas pipe. The pipeline uses a double-layer fused epoxy coating, the joint at the use of high-temperature heat shrink sleeve. Several parameters considered in coating selection are: high temperature, wall thickness, application conditions, thermal control during welding and coating properties in the laboratory. The coating was evaluated using a specially designed high temperature test. Laboratory results (impact, cure, cathodic disbondment, adhesion, immersion in hot water) indicate that the construction conditions used met the technical requirements of the project.
