...Abstract Abstract The pressure vessels are connected by pipelines to form a system. Thermal expansion of the pipeline imposes an additional load on the nozzle of the connected vessel. There are two methods to deal with the thermal expansion load of pipeline in the design of pressure vessel...

... by steam or internal pressure can easily be estimated by a conventional FEM code. However estimation of system load caused by thermal expansion of pipe materials is difficult because of the complex structures of piping system. In this study, we developed a three-dimensional FEM code which can estimate both...

... dependency of thermal stress on the diameters, thicknesses and the material properties of the layers. It is also shown that the radial and circumferential thermal stresses depend linearly on the coefficients of thermal expansion of the materials and the temperature change. As demonstrated, this solution can...
