AN ANALYTICAL SOLUTION BASED ON SHELL THEORY FOR CALCULATING STRESSES ON FULL ENCIRCLEMENT SLEEVES USED ON PIPES AND PRESSURE VESSELS

摘要

Welded full encirclement sleeve repairs are used frequently in petrochemical industries as repairs for piping and pressure vessels. This publication describes a proposed methodology for calculating the stresses on a welded full encirclement sleeve using a closed from solution derived from shell theory. The analytical results are compared with finite element results and are found to be in reasonable agreement.
