Abstract
- For transmission of high-pressure corrosive fluids, it is required to pipe that with both anti-corrosive and high strength material. One of the economical and reliable approaches is the use of Tight Fit Pipe (TFP). Tight Fit Pipe is a double-walled pipe, where a corrosion-resistant alloy liner is fitted inside a carbon steel outer pipe through a thermal-hydraulic manufacturing process. TFP is manufactured under specified conditions for conducting this research. The most influential parameter to improve these pipes' structural response is the residual stress between the inner and outer pipes. In this study, finite element analysis and experimental method were utilized to calculate residual stress between the inner and outer pipes. A 2D finite-element model was performed in ABAQUS software to simulate the lined pipe with considering the effects of heat on the mechanical properties of the pipes and nonlinear isotropic/kinematic hardening material model. Analytical and experimental (Saw cut) methods were applied to measure residual stresses of two pipes to validate the numerical method's results. By comparing the simulation results with the experimental results, an appropriate agreement has been observed.
