摘要
在输气管道内壁涂敷减阻涂层不仅可以减少内腐蚀 ,而且可以降低管道内壁粗糙度 ,起到减少输送阻力 ,提高输气效率的作用。详细介绍了减阻型涂料在国内外的应用现状 ,并对我国研制的 AW— 0 1天然气管道减阻涂料所带来的减阻效果和经济性进行了分析和评估 ,认为与国外相比减阻增输效果非常明显 ,如能在“西气东输”工程中使用 。
He resistance reducing coating on inside wall of gas pipeline can not only decrease inside corrosion, but also lower the roughness of inside pipe wall, reduce the transmitting resistance, and increase the efficiency of gas pipeline. The application status of resistance reducing coating material both home and abroad was introduced, and the reducing effect and economic benefit of the researched AW-01gas pipeline resistance reducing coating material was analyzed and evaluated. The resistance reducing effect was considered to be obviously, if it can be used on west to east gas pipeline project, the potential economic and social benefit will be obtained.
