AXI/Pro
AXI/Pro is a powerful, easy to use axisymmetric and brick finite element modeler. Bolts, nuts and holes may be included in the 3D brick models so that users can see the results of hole spacing on the stress distributions. Dimensionally accurate flange models including studs and nuts are generated automatically for six major flange standards.
- Predicts liquid or gas leakage through the flange when subject to external loads, pressure or loose bolts.
- Has ANSI, API and DIN flange dimensional data base.
- Performs an ASME Appendix 2, BFJ, EN 13445 Annex G (European rules), and FEA compliance checks on flanges
- Determines best suited bolt-up method for the leak tightness needed
- Predicts yearly total leakage reports for a series of flanges so that OSHA or DOT compliance report evaluations can be prepared
- Analyzes stresses in the flanges and bolts according to a 3D FEA analysis, ASME Appendix 2, BFJ, and EN13445 Annex G
- Evaluate the effect of loosening a single or series of bolts
Analyze large heat exchanger flanges with any number or bolts
FE/Pipe is a specialized finite element program developed for the piping and pressure vessel markets. It was created for the Engineer that doesn't have time to work with a general-purpose FEA program. The primary focus of FE/Pipe development is to create a software package that quickly and easily allows modeling of complex structures using standard design geometries. FE/Pipe is a rapidly developing program currently in use at 300+ companies analyzing simple nozzle geometries to the world's largest vacuum tower. FE/Pipe Templates allow users to custom design and analyze job specific structures without the need of learning finite element theory. FE/Pipe is a feature rich software package and each month several customers discover how they use FE/Pipe.
The current customer FE/Pipe Top features are listed below.
- Automatic calculation of ALLOWABLE LOADS on nozzles. FE/Pipe generates a table of allowable loads on any nozzle. The table includes the maximum individually applied value and the maximum simultaneously applied value of the load value and the maximum simultaneously applied value of the load.
- CAESAR II interfaces that allow beam models to be read into the FE/Pipe beam analyzer, and interacted with FE/Pipe shell models.
- A "Standard" Lifting Lug Design Calculator is included that recommends the size of lifting lug, the amount of weld required, and if a brace or strong back is required to reduce the moments on the lug.
- An Axisymmetric/Plane Stress/Plane Strain Model Template which provides ASME Code through-thickness integration for calculation of section membrane and bending stresses.
- An Automatic Fixed Tube/Tubesheet Axisymmetric Modeler that provides cross section stress integrations, stress breakdowns according to primary or secondary stress calculations, and auto-generated angle, cross or tee shapes with optional radiuses. Also tubesheet allowable stress according to ASME VIII div.1 App. A. Finally, tube allowable loads according to TEMA RCB 7.24.
- Input in the Nozzle/Plates, and Cylinders-Heads-Plates Template which allows the user to include the effects of varying fluid elevations to properly simulate the effect of fluctuating pressure with depth. This is required for simulating the Zick saddle analysis.
- Rotation of databases allows all intersection models to be oriented in the global coordinate system and included with other multiple nozzles or straight head bend models.
- Input and analysis for simplified code guidance for PLASTICITY and CREEP
- Harmonic excitation analysis of shell structures such as Acoustic Bottle vibration studies and Wind Dynamic calculations
- Pressure stiffening analysis giving users the effect of pressure on SIFs (stress intensification factors) and stiffnesses at nozzle intersections
Brick OLET fitting template including internal taper - AISC Structural Steel database allowing users to model angles, double angles, channels and tee geometry's
- Symmetric and Non-symmetric Brick models that analyze Flanges and Bolts with external moments
- Spherical Shell models that include options for non-penetrating Tank Legs and Crown Caps
- Shell modeling with an option to auto-connect Beam endpoints to closest shell model
- Gussets either four or eight can be added to reinforce nozzles for simulation of plastic rib reinforced nozzles and mixer nozzle supports
Taper Pad options on nozzle models - Header, Shell and Pad modeling with alternate plate meshing to improve Large Plate constructions, SIFs and Stiffnesses for run moments through the header, and individual close plate surface joining,
- Oval miter section modeling options
- Straight edge miter sections
