Comparison and selection of pressure balance ripple compensators for long-distance heating pipeline networks
In order to compare and select pressure balanced corrugated compensators for long-distance heating networks,four types of pressure balanced corrugated compensators,namely internal and external pressure bypass straight pipes,full external pressure bypass straight pipes,internal pressure straight pipes,and external pressure straight pipes,were used as research objects.Through START stress software and water resistance simulation calculation,their performance structure,stress load,and local water resistance were analyzed.Combined with successful cases in China,the characteristics and application feasibility of the four types of compensators were summarized.The analysis shows that the internal pressure straight pipe pressure balanced corrugated compensator overhead laying,with high safety,with strong pressure bearing capacity,the fine stability;The pipeline pressure loss is only 0.001MPa,initial investment is low,and the operating cost is low.Therefore,the internal pressure straight pipe pressure balanced corrugated compensator is selected.
