Piping And Pressure Component Analysis

PVPT - NozzlePro

NozzlePRO is a dedicated software solution for piping and pressure vessel components. It brings the accuracy of the Finite Element Analysis (FEA) to the engineering community for general design and analysis. The software is based on the technology offered in FEPipe with a user interface that simplifies input and allows engineers to quickly analyze piping and pressure components with a high degree of accuracy.

NozzlePRO is part of the PVPT (Pressure Vessel Piping and Tank) Design Suite.

Key Capabilities

More than 30 years of experience with surge analyses have been incorporated into NozzlePRO.

We are committed to continue doing so in every new version of the software.

NozzlePRO can perform automatic fatigue calculations to comply with piping and pressure vessel design codes. NozzlePRO contains the following modules:

  • Detailed material database MatPRO
  • API579 Fitness for Service
  • High temperature Creep-Fatigue Interaction (ASME Section III Subsection NH)
  • FE107 and FESIF
  • Improved SIF calculation according ST-LLC 07-02 PRG/ASME report

NozzlePRO also provides piping elements to evaluate the effect of pipe thermal expansion on the nozzles. This capability results in a much more accurate evaluation of loads and displacements on the nozzle and in the piping system. Straight sections, elbows, bends, intersections and linear restraints may be included in the analysis.

The technology incorporated in NozzlePRO is a significant improvement over the limitations inherent in WRC 107/297 methods. WRC methods are only accurate across a small subset of ranges found in industrial applications, whereas NozzlePRO is mainly constrained by the geometry of the component to be modeled.

The software is designed to quickly and easily evaluate nozzles, saddles, pipe shoes and clips according ASME VIII Division 2. A variety of head types are allowed including spherical, elliptical, ASME, dished, cylindrical and conical. A minimum number of values must be input to generate the model. The engineer is able to include thermal, weight, operating, occasional, pressure, wind and earthquake loads. The output is shown using comprehensive ASME code compliance reports.

NozzlePRO Applications And Examples

NozzlePRO accounts for thermal, weight, operating, occasional, pressure, wind and earthquake loads so that compliance requirements can be easily determined and met.

  • Apply multiple thermal or operating loads on a nozzle.
  • Address WRC limits, properboundary conditions and weld models.
  • Apply simultaneous loads on the nozzle and pipe.
  • Pad-reinforced lugs, clips or other supports can be placed on the knuckle radius of a dished head.
  • Inlcude seismic horizontal loads on vessel clips or box supports.
  • Apply different thermal expansion coefficients or temperatures between the header and branch.
  • Evaluate the effects of axial or transverse loads due to internal sloshing, wind loads, seismic loads or general external loads.
