Stress analysis

 

Stress analysis of the centrifugal pumps is carried out at our laboratory based on the general arrangement drawing or dimensional outline drawing of the pump owner.

For this, our staffs utilize commercial software, e.g. Cesar, etc. The results are forces and moments on each nozzle, as well as any connection on pump pressure casing. Based on the nozzles materials, as well as the pump type and orientation, the forces and moments are then judged against the requirements of the API 610, table 4 or annex F. The intent is to avoid misalignment of the pump and its driver shafts and dis-torsion of the pump pressure casing.
