What Is NozzlePRO?
NozzlePRO is a standalone solution that enables users to quickly and easily perform finite element analysis (FEA) of individual pressure vessel and piping components, without extensive knowledge of FEA modeling, analysis techniques or theory.
With capabilities designed to automate FEA validation and ASME code compliance reporting on pressure vessel and nozzle models, NozzlePRO is an efficient and accurate Design By Analysis (DBA) solution for pressure equipment designs.

The Saddle Wizard is a step-by-step interactive modeler that allows the user to design their horizontal vessel and saddle for any loading conditions.
The Pipe Shoe Wizard creates an FEA model of a pipe shoe on a cylinder to calculate local stress.
The Drawing Tools allow the user to add gussets, rings, clips and other attachments to an existing model.
For a full list of features, check out the table below.
Program | Program Summary |
|---|---|
MatPRO | MatPRO is PRG’s materials database that includes high temperature curves, allowable stress plots, NH reporting, creep-fatigue interaction diagrams, elastic-plastic stress strain curves, and fatigue curves generated as a funtion of creep temperature. |
SIF / SSI / k (PRGik) | Compares SIFs and k-factors from B31 and other codes for branch connections and elbows. Hyper De- gree of Freedom (HyperDOF) calculations can be performed for elbows with and without supports with refractory. |
High Frequency | Provides AIV calculation predictions of pressure levels from the surface of the vessel. This program is mainly used to:
|
Flaw Detection | Predicts crack growth for given stress states in components to know when the crack will reach half wall and/or thru wall for leaks. This is a quick calculation based on observed crack growth in tested low carbon steel components. |
Nonlinear Analysis | This capability computes burst pressures, sustained stress indices, twice elastic slope load levels, and a variety of load and unload conditions. |
Drawing Tools | The Drawing Tools provide hundreds of small functions to modify, evaluate and document the model created. |
FE107 | FE107 replaces WRC 107 as a calculation tool that can be applied when WRC 107 or WRC 297 correlations or assumptions are limited. ASME Section VIII Division 2 allowables are printed along with flexibilities and allowable loads for forces, moments, and pressure. |
FESIF | Calculates SIFs and k-factors for standard B31 branch connection geometries. |
FETee | Along with performing FEA of contoured tees per user input, B16.9, or EN10253 is conducted, this program mainly:

How Do I Know I Need NozzlePRO?
If you experience the following issues when designing or analyzing your pressure equipment, consider NozzlePRO to provide you an accurate analysis and expedite your workflows.
When there are multiple thermal or operating loads acting on a nozzle.
When the d/D ratio for a loaded nozzle is greater than 0.5 and WRC 107 or 297 is considered for use.
When the t/T ratio for a loaded nozzle is less than 1.0 and WRC 107 or 297 is considered for use.
When the nozzle is pad reinforced and WRC 107 or 297 is considered for use.
When there are loads acting on a nozzle and run pipe simultaneously.
When the number of full range pressure cycles is greater than 7000 and the nozzle is subject to external loads.
When the D/T ratio is greater than 100 and SIFs or flexibilities are needed for a pipe stress program.
When the D/T ratio is greater than 100 and a dynamic analysis including the nozzle is to be performed using a piping program.
When a large lug is used in a heavily cyclic service.
When pad reinforced lugs, clips, or other support are placed on the knuckle radius of a dished head and WRT 107 methods are fraught with potential errors.
When seismic horizontal loads on vessel clips or box supports are to be evaluated.
When pad reinforced hillside nozzles subject to pressure and external loads.
When evaluating large run moments, but small branch moments in a piping system.
When there are overturning moments on skirts.
When the effect of integral vs. non-integral pad on nozzle in head should be studied.
When there are different thermal expansion coefficients or temperatures between the header and branch.
When the loads on nozzles are high because of the assumption that the nozzle connection at the vessel is a rigid anchor.
