In order to research the influence of blind plate force on layout of circulating water pipes

this article discusses the influence of blind plate force on overhead circulating cooling water pipes of a combined cycle power plant according to theoretical and numerical methods. The results indicate that

for 90° elbow

the effect of nonuniform flow field on pressure distribution is negligible. For the circulating cooling water pipes with diameter of 1 420 mm and pressure of 0.262 1 MPa

the blind plate force is very large

which reaches about 60 t. Under the action of blind plate force

the displacement and equivalent stress distribution change obviously. The maximum load increment of the support hanger is 3.6 times. The blind plate force has significant effect on displacement

stress distribution of the pipe and loads of the supports and hangers. The results of this paper could provide a reference for the analysis

design and layout of large-caliber thin-wall pipelines.
