Proven Track Record

NozzlePRO is easy to use and its interactive graphics provide clear and intuitive guides. Take the guesswork out of building the design model and benefit from on-the-fly plotting of the analysis model for verification. NozzlePRO quickly generates analysis results in graphical and tabular formats and clearly represents system pressures, moments, temperatures, and loads. A powerful interactive toolbox enables you to dissect and manipulate models.

NozzlePRO from Paulin Research Group is available for purchase from Intergraph.

Integrate FEA with CAESAR II and PV Elite

Since NozzlePRO enables FEA results to be seamlessly incorporated within traditional code-based analysis, projects can benefit from the accuracy of FEA and the practicality of code-based analysis. For example, the flexibilities and SIFs analysis results can be easily combined with Intergraph’s CAESAR II or PV Elite to improve the overall analysis of piping systems or vessels so they are neither over- nor under-designed.

Extend Beyond Code-Based Analysis

NozzlePRO can analyze components that fall outside code limits. It can also calculate more accurate maximum allowable loads and stresses. Therefore, it is able to accurately establish consistent safety factors for analysis. These more accurate results lead to improved efficiencies in design and help increase the life span of piping systems and associated equipment.

Quickly Build Accurate Analysis Models

Component input is quick and straightforward while also allowing customization of the mesh and boundary conditions. For even more accurate evaluation of loads and displacements on the nozzle and in the piping system, users can pipe away from a piping junction on a vessel head or cylinder to evaluate the effect of the thermal expansion on a nozzle. Straight sections, elbows, bends, intersections, and linear restraints may all be included in the nozzle analysis.
