Efficiency of laying pipes made of ductile iron in seismically hazardous areas
Summary
At the current stage of housing and utilities reformation, with increasingly stringent requirements for the reliability and durability of municipal utility pipelines, the need to develop requirements for the selection of pipe materials and types tailored to the specific conditions of the installation and operation of urban water supply systems is becoming increasingly important. Proper selection of pipe materials is crucial to provide for the reliability of water pipelines in earthquake-prone areas of Russia. It is demonstrated that ductile iron pipes are currently the most promising choice for use in drinking water supply systems in earthquake-prone areas. It is noted that ductile iron possesses high strength properties similar to those of low-carbon steel (ultimate tensile strength, yield strength, and percentage elongation) and improved corrosion resistance. Information on seismic resistance calculations for ductile iron pipelines is provided to verify their safety for use in earthquake-prone areas.
