This paper presents a simplified method for calculating the different stress components induced in pipe elbows by a concentrated load applied at its integral lug attachment. The equations generated are based on extensive parametric study using finite element techniques. The equations also utilize a new dimensionless ratio that has been developed from parameters defining the lug size, the elbow size, and the pipe thickness. A total of 124 combinations of these three parameters representing a wide range of their variation has been considered. The consistency of the results obtained confirms the accuracy of the equations for a wide range of all parameters involved. The equations also serve as a means for calculating the mechanical load stress intensity as required by Section III of the ASME Boiler and Pressure Vessel Code for Class 1 piping systems.
