NozzlePRO

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.
