Modeling and analysis of thermoplastic composite pipe under tensile loading

Thermoplastic composite pipes (TCPs) are becoming viable alternatives to steel pipes for transporting oil, gas,and other fluids, as well as tubes for coil tubing equipment, due to their superior properties, such as corrosionresistance, lightweight, high-pressure rating, and high strength. TCPs typically have a cross-section consisting of threelayers: inner liner, composite laminate, and outer jacket. Because the load-bearing layer is a composite laminate, theload-bearing capabilities of this composite should be investigated. In this study, the software ANSYS was used todevelop FEA models to predict the stress distribution of the Pipe. Tsai-Wu failure criteria were utilized to estimate thePipe's maximum tensile loading. On the tensile loading of TCPs, the effects of crucial parameters, such as the numberof composite layers, were studied. Analytical and finite element analysis methodologies yielded conclusions consistentwith each other and supported by available experimental data.
