The responsibility of the Piping Engineer includes ensuring the Structural integrity of the pipe, which should serve the estimated life time without a flaw. Piping system should have the flexibility to limit the stresses generated in it due to the weight, pressure, temperature, external loadings etc., with in the allowable stress value for the material, based on the governing code.
Static hydraulic analysis shall be performed for pump sizing, pressure drop calculation etc. Hydraulic analysis also helps to study whether the piping system meets its flow requirements, which is the basis of the design. Surge analysis shall be performed for the piping system where the transient events may create peak surge pressure in the piping system. Failure of piping system may happen if the peak surge pressure is higher than the design pressure of the piping system.
