- This technical report studies the linearized stresses according to ASME (i.e. membrane and membrane plus bending stresses) in an infinite-long cylindrical pipe subject to an uniform internal pressure. In particular, the linearized stresses calculated using the finite-element method (as computed by the free and open source tool [Fino](https://www.seamplex.com/fino)) depend on the number of element through the pipe thickness. These numerical results are compared to the analytical solution of the infinite-pipe problem. Differences between first and second-order grids, rate of convergence and errors as a function of the computational effort are addressed. The main conclusions are that it is mandatory to use at least second-order elements to accurately compute the membrane plus bending stresses and that two elements along the pipe thickness are enough to reasonably compute the linearized stresses.
