Pressure equipment design and analysis
CRO-MECHANIX produces strength calculations by design by formulae (DBF) and design by analysis (DBA) with finite element analysis (FEA). It also delivers the thermodynamic calculation, 3D model, drawings and documentation for the notified body under PED 2014/68/EU.
The work is delivered online for clients in Croatia and Europe, from the documents you send by email.
Combustion and heat transfer calculations give the heating surfaces and tube layout of boilers, economizers, steam superheaters and heat exchangers. The resulting geometry and operating temperatures go straight into the strength calculation of the same equipment.
The outcome of strength calculations by design by formulae (DBF) is a report in which every adopted thickness is traceable to a clause of the standard.
Software: Hexagon PV Elite, Hexagon VVD, DIMy
When a nozzle, support or legs fall outside the scope of the formulae, CRO-MECHANIX carries out a stress analysis by linear FEA to EN 13445-3 Annex C, EN 13458-2 Annex A, ASME Section VIII Division 2 or AD 2000.
The same method checks seismic action to EN 1998-1-1 and wind to EN 1991-1-4 on non-standard structures.
Software: Autodesk Inventor Nastran, Abaqus
The parametric 3D model takes its dimensions and thicknesses from the calculation. The fabrication drawings and the calculation report therefore describe the same design.
Under 3D modelling and drawings of pressure equipment, CRO-MECHANIX models fire-tube boilers, gas separators, deaerators, LPG tanks and complete boiler houses.
Software: Autodesk Inventor Professional
Delivery also includes the technical documentation for the notified body under PED 2014/68/EU.
