NozzlePRO

NozzlePRO is a standalone solution that enables users to quickly and easily perform FEA of individual pressure vessel and piping components.

MatPRO

Is PRG’s own 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 function of creep temperature.

AxiPRO

FEA of flanged joints and other axisymmetric geometries. 3D, nonlinear finite element models of gaskets, bolts and flanges are used to calculate stresses, displacements and leakage in and around the flanged joint. Code evaluations of the joint are performed in accordance with ASME Section VIII-1 Appendix 2, ASME BFJ and EN13445 Annex G.

661PRO

661PRO analyzes header box nozzles for air-cooled heat exchangers. It also performs tube load analysis for multiple nozzle loads per ASME Section VIII-1 Appendix A. All nozzle loads are applied to the perforated tubesheet and analyzed per ASME 2004-Div. 2 Art 4-9.

FE107

FE107 replaces WRC 107 and 537 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

Provides a FEA of contoured tees per user input, B16.9 or EN10253. EN10253 types A and B tees can be defined and thickness profiles determined and appropriate finite element models constructed. Elastic models to produce SIFs and k-factors are generated automatically, along with nonlinear calculations (with or without pressure) for SSIs and loads thru the branch or run. Users may locally thinteesthin tees, define the crotch radius and/or the thickness profile around the branch to run penetration line.

FEBend

Provides a FEA calculation of the local stress and SIFs, SSIs and k-factors for 90 degree elbows with and without supports. Supports include round stanchion as well as structural attachments.

PCL-Gold Pipe Stress

For piping systems in which there are well-known weaknesses in code approaches, PCL-Gold provides an alternative method for determining whether or not the weakness can cause a potential problem.

Pipe Shoe Design Wizard

Compares CAESAR II or PCL-Gold selected nodes’ restraint loads at shoe support locations with the allowable loads from a library of FEA shoe supports for every load case in the piping model. The comparison provides shoe design capabilities as well as validation that existing shoes are appropriately designed.

High Frequency

Acoustic Induced Vibration (AIV) calculation includes the prediction of sound pressure levels measurable away from the surface of the vessel. This tool is used mainly to estimate strength of branch connections and elbows with trunnions when compared a straight pipe.

PRG performs high frequency vibration tests to confirm surface integration and prediction of damaging SPL levels.

Methods in IEC 60534-8-3 for gas flows are used to generate predicted SPL spectrum. Stresses in high frequency modes are scaled to match defined spectrum responses and predict expected cycle lives.

Cumulative Damage

Performs fatigue analysis and cycle counting for piping systems that were built using CAESAR II or PCL-Gold. This tool can be used in the following situations:

• When cycles are outside limits

• When fatigue limits exist in a piping system

• When known fluid loading produces high cycle forces

• When cracks or local thin areas are present

• When multiple significant thermal and/or pressure cycles are present

• Elastic follow-up evaluation

BOS B31

The fluid-structure interaction using frequency domain analysis of piping systems is used to comply with the B31.3 loading requirements in Para. 301.5.

SIF / SSI / k (PRGik)

Compares SIFs and k-factors from B31 and other codes for branch connections and elbows. Hyper Degree of Freedom (HyperDOF) calculations can be performed for elbows with and without supports with refractory.

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.

MimOut Point Clouds

Plant scan data (point cloud data) processing is combined with 3D modeling utilities to compare computer model estimates of what is in the field to what physically exists. Both high and low-resolution editing is provided.

Drawing Tools

Available with all modules except AxiPRO, the Drawing Tools provide hundreds of small functions to modify, evaluate and document the model created.

Nonlinear Analysis

This capability computes burst pressures, sustained stress indices, twice elastic slope load levels, and a variety of load and unload conditions.

Fitness for Service

Perform level 1, level 2 and level 3 (through the Drawing Tools) Fitness for Service calculations. Local thin areas and cracks can be added into the model for level 3 calculations. API 579/ASME FFS-1 allows the use of ASME Section VIII Division 2 Part 5 for Elastic, Elastic-Perfectly Plastic and Elastic-Plastic FEA analysis.

FEATools

Transform your piping model (from CAESAR II and PCL-Gold) by including upgraded branch connections (with the addition of rigid elements and restraints) to better simulate real-world displacement and forces. The FEA-based calculations provide the necessary k-factors, SSIs and SIFs that will be added to every branch connection.
