Equivalent Stress Cycles Based on District Heating Operation

Abstract:

We investigated supply water temperature of the district boiler between 2006 and 2014.And calculated the design life cycles of heating pipeline based on the district boiler as the heat source. Then superposed the number of the design life cycles caused by pipelines accidents and district boiler of the main trunk lines, distribution lines and subscriber connection line, we obtained the design life cycles of different heating pipes. This result can provide a basis for fatigue damage analysis of heating pipe fittings.
