Hydraulic component of alternative pipe materials and protective coatings in trenchless renovation of pressure pipelines

Summary

The results of experimental hydraulic studies of trenchless renovation of pressure pipelines with different protective coatings are analyzed. The studies were carried out in the laboratory of the Water Supply Faculty of the Moscow State Civil Engineering University. The cross-plots of specific resistance – diameter of pipelines made of different materials (protective coating) relationship are presented. The solution of the task of evaluating hydraulic compatibility of some pipe materials and protective coatings used in the relative technologies of trenchless renovation is given.
