FE/PIPE - Finite Element Analysis for Piping / Vessels

FE/Pipe is a template-driven Finite Element Software Package, specifically designed for the needs of the piping and pressure vessel enginees. FE/Pipe (as well as all of its associated modules in the PRO series) generates automatic code compliance reports - comparisons to ASME Section VIII, Division 2, Appendix 4 and 5 rules and stress categories.
Build models such as intersections, flanges, saddles, low tank settlement, structural steel and view instantly using Direct 3D graphics engine. Parent-Child database functions allow the user to join together individual models into one large system for analysis. Triangular elements eliminate the need for all model sections to have the same element density patterns the user can include more elements only where you need them.

Buckling & Plasticity
Buckling is a concern in piping and pressure vessel geometries with large D/t ratios and/or external pressure. FE/Pipe includes the ability to analyze buckling using traditional bifurcation buckling and elastic-plastic collapse analysis. In addition, FE/Pipe also provides full capabilities for elastic-plastic analysis with kinematic hardening. The elastic-plastic solver can also be used to generate lower bound collapse loads.

Thermal Solutions
In some systems, thru-the-wall thermal gradients can cause significant stresses. FE/Pipe can be used to analyze steady state and transient thermal stresses in both solid and axisymmetric elements. Applications might include hot-box design verification for skirt supported vessels, catalyst bed support rings, and other discontinuities.

When FE/Pipe is useful to your design:
To analyze any nozzle loads (WRC 107/297 are not comprehensive and often inaccurate).
To analyze large branch/shell intersections (d/D>0.50)
For piping or pressure vessels with D/t rations greater than 100.
For flange analysis - get the REAL operating bolt load, not a pseudo "code" load and estimate flange leakage.
To calculate accurate SIFs and flexibilities for your piping analysis.
For external loads on saddle supported vessels.

When FE/Pipe is critical to your design:
To satisfy code requirements for buckling in complex systems.
In order to get realistic stresses for nozzles with external loads.
When your piping systems exceeds D/t>100. Piping code rules are not meant for large D/t systems.
To perform accurate fatigue analysis for nozzles or attachments.
When your design isn't covered by code rules - large angle cones, rectangular openings, etc.

FE/Pipe includes many standardized templates that allow the designer to quickly and easily build finite element geomeries that had previously taken days and weeks. Changes to geometry and loads are instantaneous - no need to completely rebuild the model. The following list details the standard templates currently available for use with FE/Pipe:

Unreinforced Fabricated Tee
Pad Reinforced Fabricated Tee
Welding Tee
Hillside Tee
General Nozzles, Plates & Shells
Beam Models
Cylindrical Strings
Symmetric Geometries (2d & Brick)
Axisymmetric Flange
Low Tank Nozzle
FCC Wye Fitting
Singular Nozzle Large Sizes
Head Structures
Wye Intersection
Tank Settlement
Plate Heat Exchanger
Simple Pipe Supports
Tangential Nozzle
Shell-to-Head Nozzle
Olet-Type Fitting (Brick)
UFT or RFT (Brick)

Output or code calculations are given directly for the following codes.
- ASME Section 8, Division 2, Appendix 4
- ASME Section 8, Division 2, Appendix 5
- ASME Section 8, Division 1, Appendix 2
- ASME Section 8, Division 1, Appendix BFJ (proposed)
- AISC Manual of Steel Construction
- ASME Section 8, Division 2, Article 4-9 Tubesheet stresses
- NEAM Tube Buckling Calculations
- ASME Section VIII, Division 1, Appendix A Tube and Tubesheet strength calculations.

Other codes/methods are considered or used for comparative calculations.
- SIFs and Flexibilities for B31.1, B31.3, and any other piping code
- WRC 107/297 Nozzle Stress Calculations
- N-318 Lug Calculations
- N-392 Round Attachment Calculation
- Code area replacement calculations at nozzles
- Zick calculation for saddle supported vessels (satisfies new Division 2 and several existing foreign codes such as BS5500)
- Nozzle Flexibilities per WRC 297 and NB 3685.

The primary code output is for ASME Section VIII, Division 2, Appendix 4 and 5. But, these results can be used to satisfy virtually any code in the world so long as the basis of the stress categorization is similar to that given in ASME. Flange results are given for ASME Section VIII, Division 1, Appendix 2 and proposed Appendix BFJ. Flange results are also available for EN 13445.

AISC output and code calcs are available for structural beam models. The axisymmetric template can generate tube sheet models for heat exchangers. This extends upon the code rules provided in all codes with exchanger rules (TEMA, ASME, BS5000, etc). Stress Intensification Factors generated in many of the templates can be used to improve virtually any piping code (B31.1, B31.3, etc). API 653 can be satisfied using FE/Pipe's Tank Settlement template. API 650 Appendix P can be satisfied using FE/Pipe's Low Wall Nozzle Tank template.

FE/Pipe features 18 DOF beam elements (that model ovalization/warping), and links to the latest ASME and B31.3 Material Databases, WRC474 and BS5500 Fatigue Analysis, Extended ASME VIII Div2 App 5 Fatigue curves. 

FE/Pipe also includes several integrated modules. These modules are part of the PRO series that bring specialized attention to the most common problems encountered by engineers and designers today. Detailed descriptions are included further down on this page.

NozzlePRO - Analyze individual nozzles, saddles, clips or pipe supports on a variety of head types.
AxiPRO - An axisymmetric & brick FEA modeler, designed to analyze flanged joints & other axisymmetric geometries.
MatPRO - Materials Database that includes High Temperature Curves, Creep-Fatigue interactions and ASME Stress Plots (Div1/2)
FE661/661PRO - Analysis of rectangular box headers used in air coolers
Fitness for Service - Evaluation of cracks and thin areas
ASME NH Reporting 
High temperature local stress evaluation reports

The FE/Pipe Maintenance plan also includes access to these modules:

PCL-Gold Pipe Stress Program
