PRODUCT SHEET BENEFITS: • Improved WRC 107/297 analysis for nozzles and attachments. PAULIN RESEARCH GROUP NOZZLEPRO™ FOR INTERGRAPH® PV ELITE® AND CAESAR II® • More accurate analysis on saddle supports (Zick). NozzlePRO is a standalone solution that enables users to quickly and easily perform • More accurate design and analysis. Engineers can perform FEA without the need for extensive knowledge of FEA modeling • Better analyses of components in cyclic service. • More cost-effective designs. • Reduced design changes and iterations. • More accurate nozzle-loading conditions. Finite Element Analysis (FEA) of individual pressure vessel and piping components. or analysis techniques. 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 plot- • More accurate allowable loads on nozzles. ting of the analysis model for verification. NozzlePRO quickly generates analysis results temperatures, and loads. A powerful interactive toolbox enables you to dissect and in graphical and tabular formats and clearly represents system pressures, moments, manipulate models. • Analyze components outside code limits. NozzlePRO from Paulin Research Group is available for purchase from Intergraph®. • Calculate more accurate SIFs and k-factors. Integrate FEA with CAESAR II and PV Elite • Use FEA results in PV Elite® and CAESAR II®. • Perform rigorous FEA of special components: 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 - Hillside nozzles. 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. - High-temperature analysis. - Basic FFS evaluation. Extend Beyond Code-Based Analysis NozzlePRO can analyze components that fall outside code limits. It can also calculate - Nozzles with attached piping. more accurate maximum allowable loads and stresses. Therefore, it is able to accu- - Complex loading conditions. rately establish consistent safety factors for analysis. These more accurate results lead - Saddles, pipe shoes, and clips. to improved efficiencies in design and help increase the life span of piping systems and • Access a complete material properties database. associated equipment. • Support axisymmetric and brick models. Quickly Build Accurate Analysis Models • Create tabular and graphical result reports. • Generate fatigue calculations. 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.

Results and Analysis Based on Research • Evaluate overturning moments on vessel skirts. Realistic flexibilities in a nozzle typically result in much lower stresses (higher allowable loads) on nozzles. The original design code SIF • Determine the effect of an integral vs. non-integral pad on a nozzle located on a head. values for intersections were derived from work performed in the • Design pipe shoes for self-weight, liquid weight, and axial loads. 1940s by A.R.C. Markl. Most of these experiments were performed on a single-size piping run. All other SIF values were extrapolated from this...
