Pipe classes can be designed as per calculation codes. The different calculation codes do not give the same result. The PCC software created by and used at Red-Bag allows the switch between calculation codes without any change to the pipe class input. The possibility to switch between the calculations codes such as the ASME B31.3 and EN 13480-3 gives the engineering a better understanding of the critical pipe class components.
In this case the fittings have been corroded and an assessment was requested whether the fittings were fit for service. The ASME B31.X series do not give enough details to calculated the remaining strength of the fittings. For this European customer it was possible to switch the EN 13480-3 and create the detail calculations based on the measure thicknesses. (Internal)
