The stress calculation reports are a critical item in the verification of the design of the valves. Many points of attention are checked with these calculations that go far beyond the oil & petrol industry level of details. We prepare your calculation reports to demonstrate the validity of your design according to codes or design specifications. These calculations are mostly based on material resistance theory and may used 3D finite element analysis if requested.
Valves are submitted to thermal and mechanical transients during their lifetime. We perform for you specific fatigue calculations to check the design of the valves. These calculations are either performed by means of simplified rules given in design codes or by means of 3D finite element analysis combined with post treatment codes like ASTER for example.
