Finite element analysis (FEA) is a valuable technique for analyzing mechanical components and systems. The finite element method is a useful tool for predicting and evaluating component responses to loading and providing key information as to how it will perform in service. We are able to do flexibility analysis to predict the mechanical performance of a piping system or pipeline, according to the applicable code B31.3, B31.1, B31.4, B31.8 and other codes that apply. We can to check the load on the equipment due to the restrains resulting of the piping analysis and recommend solutions to prevent failures and malfunctioning in a piping systems.
