The thermal expansion of the plant heat supply pipe network is often absorbed by π-shaped bends.Different types of π-shaped bend exhibit different support reactions,which is classified into six typical types.The corresponding finite element models of different types of the pipe systems are established.Through calculation and analysis of the finite element models,the support reaction performances of different types of π-shaped bend in various spaces are conducted in a comparative study,including axial,horizontal and vertical reaction values of the plant heat supply pipe network,as well as support bearing separation.
