WRC 537 & WRC 297- Nozzle Loads Design
The external loads imposed on fixed equipment by piping should be below the allowable loads of the equipment. Calculation and evaluation of localized stresses due to the concentrated forces and moments are not that much easy. Piping stress engineers should send the actual forces and moments of piping stress analysis to manufacturers to get the loads approved. Although the finite element analysis is accurate, however it could be expensive to perform. So WRC 537 & WRC 297 Bulletin can be used to calculate and evaluate such stresses. Welding Research Council Bulletin #537, Precision Equations and Enhanced Diagrams for Local Stresses in Spherical and Cylindrical Shells Due to External Loadings for Implementation of WRC Bulletin 107, and Welding Research Council Bulletin 297, Local Stresses in Cylindrical Shells Due to External Loadings, Supplement to WRC 107, are the most valid references for calculation of such stresses. This course covers the concepts behind these bulletins, and the common tools used to check the forces and moments imposed on equipment will be trained. Furthermore other methods which can be used instead of these bulletins will be presented especially for rotary equipment.
- Revision of WRC 537-2010 and WRC 297-1984 will be examined.
- More detailed information will be submitted on request.
