Programs in NozzlePRO
Along with a variety of features, NozzlePRO utilizes several programs to provide the ultimate FEA solution for pressure equipment designs. A few include:
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 allows the user to add gussets, rings, clips and other attachments to an existing model.
...
Vessel Link allows the user to import models of any file type from DesignCalcs, Finglow, Codeware Compress and other Pressure Vessel design software to perform FEA.

Additional Programs
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 Degree 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 Computes burst pressures, sustained stress indices, twice elastic slope load levels b, 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 createdDegree of Conservatism | This tools aids in determining the degree of conservatism on models. |
FE107 | FE107 replaces WRC 107 as a calculation tool that can be applied when WRC 107 or WRC 297 correlations calculations or assumptions are limited. ASME Section VIII Division Div 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. | |
