Abrasive wear resistance and service life of pipes made of fiber-glass composite

This article presents studies of the abrasive wear resistance fiber-glass composite pipes inner surface, which are laid us-ing microtunneling technology under construction drinking water pipes, irrigation and sewerage systems. Due to a very smooth have high coefficient fluid flow speed transmission through pipe low coeffi-cient roughness. When in long-term operation, movement solid particles pipeline eventually causes walls pipe. The study data on allows calculating pipeline's operability controlled conditions, predicting period trouble-free opera-tion pipelines making reasonable choice material for manufacturing. objects glass samples were selected, manufactured by LLC «New Pipe Technologies» using method continuous winding with an layer based on: orthophthalic polyester, isophthalic polyester vinyl ester resins. assessment overall surface was fulfilled test equipment according Darmstadt (GOST R 55877-2013, B). simulating abrasion linings that may occur real operating conditions. Crushed quartz used as material. According results research, arithmetic mean values safety coefficients deter-mined depending number cycles. select most promising polymer matrix production fiberglass both supply sewerage.
