This document contains calculations for the trunnion support of a pipe. It provides input data on the pipe dimensions and material properties, as well as loading conditions. The calculations determine the linear loads, bending stresses, primary stresses, and combined stresses on the pipe. The results indicate that the circumferential stress of 163.03 MPa and longitudinal stress of 170.73 MPa exceed the allowable stress of 148.94 MPa, meaning the current trunnion design is inadequate for the given pipe and loading.
