Chrysolite-cement pipesin hot water supply networks ХРИЗОТИЛЦЕМЕНТНЫЕ ТРУБ В СИСТЕМАХ ГОРЯЧЕГО ВОДОСНАБЖЕНИЯ
In the article, its co-authors assess different options of application of chrysolitecement pipes in hot water supply networks either in combination with or instead of steel pipes. The co-authors have proven expedient application of chrysolite-cement pipes both in the event of trenchless pipe laying, and in cases of other pipe laying methods, especially in rural areas.Permanent loads, including weight and soil pressure (q), own weight of pipes, ownrp.weight of the heat carrier, influence of temperature and humidity of the heat carrier, andinternal pressure were considered in the research into the properties and installation conditions of chrysolite-cement pipes. The research findings have proven that chrysolitecement pipelines demonstrate a 35 – 50 % safety factor in the event of subterranean trenchless pipe laying at the depth of .8+ meters, depending on the pipe diameter, types and consistency of the soil, and traffic intensity of the motor road above the pipeline.Analysis of temperature fields of a chrysolite-cement pipeline demonstrates that chrysolite-cement pipes can be laid using a simplified thermal insulation pattern due to their low heat conductivity, if the pipe wall is sufficiently thick. Boiler ash widely available in rural areas can be used for insulation purposes, or, alternatively, no thermal insulation can be used.Any works associated with the laying of pressurized chrysolite-cement pipelines are to comply with all design-related requirements. The works pre-construction assignments, excavation works, delivery, visual examination and installation of pipeline elements, thermal insulation of pipes, pipeline strength and tightness testing, thermal insulation of ring joints. Any pipes and joints are to be thoroughly examined and tested. Arrangement of hot water supply networks made of chrysolite-cement pipes is efficient in terms of their steel consumption rate, labour resources consumption rate, capex and reduced costs. The bigger the pipe diameter, the higher the efficiency of hot water supply networks made of chrysolite-cement pipes.
Рассмотрены различные варианты применения хризотилцементных труб в системах горячего водоснабжения вместо или вместе со стальными трубами. Обоснована целесообразность применения хризотилцементных труб при бесканальной прокладке трубопроводов, при других способах прокладки, особенно в сельской местности. Подчеркнута роль применения хризотилцементных труб в плане теплосбережения, экономии бюджетных средств и в качестве альтернативного решения проблем, связанных с заменой выходящих из строя стальных трубопроводов.
