柔性复合高压输送管质量研究

Research on Quality for Flexible Composite High Pressure Conveyor Pipes

现各油田实行经济化和实用化采购石油管材,普通钢管由于腐蚀穿孔情况,经常发生在很多场合已经被各种塑料管材所取代,而柔性复合塑料高压输送管作为塑料管的重要组成部分,近些年被各大油田广泛采用,并取得了良好的效果。针对目前国内油田采购柔性复合塑料高压输送管的依据SY/T 6662.2—2012,简要介绍了柔性复合高压输送管的结构和工艺流程,并提出了SY/T 6662.2—2012标准异议和柔性复合高压输送管的质量控制要点。

Nowadays,oil fields have been purchasing oil pipes of the economic and practical,ordinary steel pipes were replaced by various plastic pipes in many occasions due to often corrosion and perforation.As an important part of plastic pipes,flexible composite plastic high-pressure transmission pipes were widely used in oil fields in recent years,and good economic results were achieved.At present,the basis gist of purchasing flexible composite plastic high-pressure transmission pipes in domestic oil field was SY/T 6662.2—2012.It was briefly introduced that the structure and process flow of flexible composite high-pressure transmission pipe,and it was put forward that objections to SY/T 6662.2—2012 standard and quality control points of flexible composite high-pressure transmission pipes.
