The Finite Element Method is a common and well-used method for pipelines stress analysis, also pipelines strains. The calculated pipeline wall thickness is determined taking with regard to production inaccuracies, contribution to corrosion or erosion and the absolute value of the negative tolerance taken from material standards, or according to the instructions of the pipe manufacturer. The most important thing is to determine all the forces, loads and moments on the body. It is necessary to determine all dead loads, live loads and environmental loads. It is necessary to accept special loads, such as pressure test loads, dynamic loads, or support drops.
