Pipeline isolation tools from three different manufacturers were evaluated using full-scale testing and numerical modeling to evaluate stresses generated in 24-inch diameter pipe material considering tool-induced loads and internal pressure. Finite Element Analysis (FEA) was conducted to calculate stresses and strains considering different pipe sizes, material grades, and internal pressures. The FEA results were used to generate a user-friendly parametric tool that was validated with measurements made using strain gauges installed on the test spools. The program demonstrated that the isolation...
Pipeline isolation tools from three different manufacturers were evaluated using full-scale testing and numerical modeling to evaluate stresses generated in 24-inch diameter pipe material considering tool-induced loads and internal pressure. Finite Element Analysis (FEA) was conducted to calculate stresses and strains considering different pipe sizes, material grades, and internal pressures. The FEA results were used to generate a user-friendly parametric tool that was validated with measurements made using strain gauges installed on the test spools. The program demonstrated that the isolation tools are an effective means for isolating pressures without inducing excessive levels of stress or damage to the internal pipe surfaces.
