The Hydraulic Institute released an updated Applied Nozzleloads Standard (ANSI/HI 9.6.2 − 2011). The new applied nozzleloads standard includes recommendations for assessment of applied nozzle loads for the following pumps types:

· Horizontal end suction single-stage (ANSI/ASME B73.1, B73.3, and B73.5M)
· Vertical in line single-stage (ANSI/ASME B73.2)
· Axial split-case single and two-stage
· Vertical turbine short-set pumps

The updated standard contains additional explanatory information regarding the criteria for pump nozzle loading allowances and includes more detail regarding the material requirements for pump casings and hold-down bolts. The revised standard also contains new and improved graphics to support the text and enhance user understanding. Also, the equations and methodology are explained using more sample problems and greater educational content.

The Applied Nozzleloads Standard (9.6.2 − 2011) is available at the HI eStore. HI Members receive a 25 percent discount. Contact [email protected] for further information or assistance ordering.

Chair, Fred Walker, Weir Floway and Vice-chair, Lucian Dobrot, TACO, Inc. led the committee that updated this standard.
