Piping imposed loads are external forces and moments acting on pump suction and discharge nozzles. API 610 2010, 11th Edition, Table 5, provides a basis for nozzle sizes DN 50 to DN 400 for external forces and moments on pump nozzles. There is a frequent need in the industry for pumps of larger volumetric flow rates to have nozzle sizes larger than DN 400. The fast-track requirements of a project schedule needs a realistic and quick methodology for the pump manufacturer and piping stress engineer to have a basis for calculating external forces and moments imposed on nozzle sizes larger than DN 400.

This paper provides a methodology for determining forces and moments on pump nozzle sizes larger than DN 400. The methodology is based on the practical aspect of the most important property of pipe, which influences the quantity of force and moment it can impose.
