SIMULATION OF THE OPERATION OF A PRESSURE PIPELINE WITH AN INTERNAL LINING OF A PROTECTIVE COATING
Main Article Content
Abstract
The article presents the results of alternative methods for determining the hydraulic characteristics of a deteriorated pressure pipeline with a Subcote FLP spray-on protective coating applied to its inner surface. The results were processed using automated programs, with an ultimate goal of determining and comparing a number of hydraulic characteristics, resulting in energy indicators of pipeline’s performance during water transportation. Approaches are presented for identifying the dynamics of possible transformations of certain pipeline hydraulic parameters, specifically, hydraulic friction coefficients and equivalent roughness, when using the studied protective coating after its service over a certain time interval and with changing ambient temperature conditions. Dependencies for changes in these coefficients, and their impact on the pipeline's performance energy indicators during long-distance water transportation were obtained by calculations.
