Selection of load variation factor of spring hanger and optimization design of steam/water pipe support and hanger
At present,China's thermal power plant steam/water pipeline design standard stipulates that the load variation coefficient of spring hangers should not exceed 25%.Accordingly,the designed proportion of the constant support hanger is too high,and the"illegal"transfer of the load will cause the pipe operation deviates from the design line,and the stress increases.This paper analyzes the relationship between the constant degree and the load variability factor of constant hanger.The optimization design case shows that,properly increasing the load variation coefficient of spring hangers in the design of steam/water pipelines can increase the proportion of spring hanger configuration and reduce the occurrence of abnormal pipeline expansion.
