This Practice provides designers and engineers with requirements to help reduce the Total Cost ofOwnership (TCO) of rotating machinery by determining allowable piping loads and piping loadapplications.Comment Owner experience has shown that designing machinery piping to the maximumpublished allowable loads results in low mean time between repair (MTBR) andhigher than acceptable maintenance costs.This Practice limits the application of the entire maximum allowable nozzle load during theequipment installation design, allowing some reserve margin to maximize the possibility of thefinal installation actually remaining within the allowable loading.This Practice drives the stated, published and calculated allowable nozzle loads to become moreperformance based, tied more closely to actual effects on the MTBR and TCO for the machineryin order toa. Promote the highest reliability for vital or sensitive machinery and the determination ofthose allowable loads that will allow the achievement of that reliabilityb. Allow spared (essential) machinery to be more heavily loaded, and encouragemanufacturers to either furnish allowable load data or be in accordance with a publishedstandardc. Encourage machinery manufacturers to generate more meaningful reliability-basedallowable nozzle load recommendationsd. Encourage standards organizations to look at the basis for their allowable loadvalues/calculation methods and verify the effects on the demonstrated MTBR and TotalCost of Ownership (TCO)This Practice describes the requirements for calculating allowable piping loads and theapplication of those loads for rotating machinery including pumps and compressors (centrifugal,reciprocating and rotary screw), steam and gas turbines, and liquid ring compressors. Also, thisPractice may be used on fans and blowers after consultation with the manufacturer.This Practice describes the requirements for allowable nozzle loads for vital or sensitivemachinery and for essential (spared) machinery.This Practice also outlines the requirements for minimizing loads imposed on equipment by thepiping systems.
