The full knowledge and the familiarity with all the existing design codes such as ASME, BS 5500, CODAP, Stoomwelzen, AD Merkblatt and GOST allow us to develop the best design from the mechanical point of view. Furthermore, the in-house presence of FEM experts, together with the several ANSYS licenses, make the Finite Element Analysis a powerful instrument in our hands, for the design of critical parts of the equipment.

In addition to the mechanical design, Walter Tosto WTB has strong skills in the development of the thermal and fluid-dynamic design starting from Process Data Sheets, ensuring all the required guarantees to our customers.

Our design activities include:

• 3D simulations
• Stress analysis by finite elements methods
• Fracture mechanics analysis
• Static analysis in steady and unsteady conditions
• Fatigue analysis
• Creep fatigue damage evaluation
• Thermo-hydraulic design of heat transfer systems

Thanks to our qualified personnel (ASME and ISO9712) and to our cutting-edge equipment, we are enabled to perform all Non Destructive Testing (NDT) checks in-house.

X-Ray NDT

For X-Ray NDT we own:

  • 3 Iridium 192 sources with maximum capacity of 150Ci – up to 90mm thickness
