NozzlePRO v12.0

Finite Element Analysis provides the right answer.

NozzlePRO addresses many needs of PVP engineers working in today’s market.
Typical pressure vessel design codes, such as ASME Section VIII, cannot address all design cases. For instance, external loads on nozzles are not addressed within the Code. In such cases, engineers need to go outside of the Code and apply recognized design procedures such as finite element analysis using NozzlePRO. Simplified calculation methods commonly used in the PVP industry such as WRC 107/297 are based on limited test data and are known to be inaccurate in many cases. NozzlePRO provides realistic
answers for all cases.

  • NozzlePRO is designed to quickly and easily evaluate nozzles, saddles, pipe shoes an clips. A variety of head types are allowed including spherical, elliptical, ASME,
    dished, cylindrical and conical.
  • NozzlePRO offers optional axisymmetric and brick modeling capability for select geometries, permitting a more accurate analysis of cyclic pressure stresses in
    thick-walled geometries.
  • NozzlePRO permits the user to pipe away from any NozzlePRO piping junction into a head or cylinder. Straight sections, elbows, bends, intersections and linear restraints may be included in the analysis.
