Available PROBAD-Solutions:

TRD-Sheets

The PROBAD solution ‘TRD-Sheet’ allows strength calculations of the following parts under internal pressure:

  • Cylindrical parts with up to 10 nozzles and nipples and their interaction (TRD 301)
  • Cylindrical as Y-shaped branches (TRD 301)
  • Calculation of the fatigue strength due to cyclic internal pressure or combined cyclic changes due to internal pressure and temperature for cylindrical shells with up to 10 nozzles; optional calculation of the allowable rate of temperature change, the allowable number of changes for one load cycles, the determination of the usage factor or the equal temperature rate for all load cycles (301, Anl.1)
  • Bended tubes and Elbows (301, Anl.2)
  • Dished heads and spherical Shells with up to 10 nozzles and their interactions (TRD 303)
  • Dished heads as Y-shaped braches (TRD 303)
  • Calculation of the fatigue strength due to cyclic internal pressure or combined cyclic changes due to internal pressure and temperature for spherical shells with up to 10 nozzles; optional calculation of the allowable rate of temperature change, the allowable number of changes for one load cycles, the determination of the usage factor or the equal temperature rate for all load cycles (303,Anl.1)
  • Flat heads with central nozzle (TRD 305)
  • Firetubes under external pressure (straight tube with/without reinforcing pad, fire box and corrugated tubes) (TRD 306)
  • Fatigue calculation based on the creep rupture strength for cylindrical shells, y-shaped form pieses and bended tubes and elbows (TRD 508)
