摘要

分析管壁当量绝对粗糙度对长输管网设计选型的影响,测算管网腐蚀及结垢防护经济效益.在进行长输管网设计时,应考虑随着长输管网运行时间延长,管壁当量绝对粗糙度会随着管道内腐蚀加重而增大的情况,合理配置循环泵、中继泵等设备的规格、数量,满足长输热网近期、中期、远期运行需求.延缓钢管腐蚀、结垢带来的经济效益可观,应重视管网腐蚀及结垢防护工作.

Abstract

The influence of the equivalent abso-lute roughness of pipe wall on the design and selection of long-distance pipeline network is analyzed,and the economic benefits of corrosion and scaling protection of pipeline network are calculated.In the design of the long-distance pipeline network,it should be considered that with the extension of the operation time of the long-distance pipeline network,the equivalent absolute roughness of the pipe wall will increase with the aggra-vation of the corrosion in the pipeline,and the specifi-cations and quantities of circulating pumps,booster pumps and other equipment should be reasonably con-figured to meet the short-term,medium-term and long-term operation needs of the long-distance pipeline net-work.The economic benefits of delaying the corrosion and scaling of steel pipes are considerable,and atten-tion should be paid to the protection of corrosion and scaling of pipeline networks.
