Analysis of Influence of Equivalent Absolute Roughness of Pipe Wall in Long-distance Pipeline Network
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.
