石油化工装置中衬里管道的工程设计要点

Key Points of Engineering Design for Lining Pipelines in Petrochemical Plants

对于石油化工装置中需要防腐蚀和耐磨损的输送场合,目前国内外普遍采用衬里管道以降低成本并满足生产要求。本文介绍衬里材料的选择及衬里管线在工程设计中的注意事项,包括衬里管线的布置原则、衬里管段长度的设置、调节段的设计规律、管线支吊架的选用以及后期施工阶段的检验、安装等问题。

For the conveying occasions that need anti-corrosion and wear resistance in petrochemical plants, lining pipes are widely used at home and abroad to reduce the cost and meet the production requirements. This paper introduces the selection of lining materials and the precautions in the engineering design of lining pipelines, including the layout principle of lining pipeline, the setting of the length of lining pipe section, the design law of the adjustable section, the selection of the pipe support and hanger, and the inspection and installation of the later construction phase.
