油气输送管道的粘修及防腐工艺研究

Research on Sticking Repair and Anticorrosion Technology of Oil and Gas Transmission Pipeline

油气输送管道由于所处的工作环境和其工作性质,与具有腐蚀性的物质常年接触,与土壤接触还会引发电化学腐蚀,所以油气输送管道极容易受到腐蚀的侵害,管道就会出现各种各样的问题,需要对其进行修复工作。传统的修复方式会浪费大量的人力、物力、财力,所以文中通过管道粘修方式,研究了湿法复合修复技术和预成型法复合管道修复技术,这两种方式都是通过利用胶粘剂、结合复合材料进行的粘修方法,这两种方法不仅施工简单、快捷,而且适用环境较为广泛、安全性极高。与传统的修复方式相比,该两种粘修方式是省时、省力、省财,工作人员的安全性也能得以保障。最后再对油气输送管道的防腐工艺进行了分析,用来降低油气输送管道的腐蚀速度,减少管道的修复次数,从而延长管道的使用寿命。

Due to the working environment and the nature of its work,oil and gas pipelines are in constant contact with corrosive materials,and contact with soil can also cause electrochemical corrosion.Therefore,oil and gas pipelines are extremely vulnerable to corrosion.And pipeline will have a variety of problems,which need to be repaired.A variety of problems need to be repaired.The traditional repair method will waste a lot of manpower,material resources and financial resources.Therefore,this paper studies the wet composite repair technology and the preformed composite pipe repair technology through the pipe sticky repair method.Both methods are through the use of adhesives and composites.The method of sticking repaired by materials is not only simple and quick to construct,but also applicable to a wide range of environments and high safety.Compared with the traditional repair method,the two sticky repair methods are time-saving,labor-saving,and economical,and the safety of the staff can be guaranteed.Finally,the anti-corrosion process of the oil and gas pipeline is analyzed to reduce the corrosion rate of the oil and gas pipeline and reduce the number of pipeline repairs,thus extending the service life of the pipeline.
