Features Unique to CAEPIPE

  • Multiple open windows providing simultaneous visual and textual feedback on different aspects of the model. Aids rapid and accurate understanding of model details and its response to loadings.
  • Synchronized Highlight (in all open windows) for easier pinpointing of nodes, elements and other items. Eliminates confusion and helps you to focus on the issue.
  • Dynamic updating of data across all windows (make one change in one window and all other windows reflect the change). Fewer keystrokes and mouse movements to go through; Flexibility and instant visual feedback.
  • Advanced MS-Windows technology for fast operation (memory mapped files, intelligent repainting, multithreading etc.). Results in extremely fast operation, and quick analysis times.
  • Single-click editing in Graphics window for alternative modeling. Two ways of editing model (not forced to textual screen editing only).

Pipes, Elements, Components and Supports

  • Model straight pipes, elbows, bends, valves, concentric and eccentric reducers, tees, miters, rigid elements and more. External insulation and internal lining can be specified for pipes.
  • Model expansion joints (such as slip, ball, hinge, bellows (tied and untied), gimbal, and universal joints) and elastic elements.
  • Model Jacketed pipes and jacketed bends - specify separate temperatures and pressures, separate materials and sections for core and jacket pipes. Spiders and endcaps can be specified, too.

  • Model cold springs, cut short or cut long.
  • Model beams and support structures. You can specify beta angles and end releases for beams. Shear deformation for beams is included, too.

  • Model tie rods (with different stiffnesses and gaps in tension/compression)
  • Support/Restraint types: Model anchor blocks, spring hangers, clevis hangers, constant support hangers, rod hangers, guide/pipe slide assemblies, sway braces, sway struts, vertical 1-way supports, 2-way restraints, U-Bolts,U-straps, clamps etc., using generic rigid/flexible support types. Include anchor and nozzle movements (thermal, seismic and settlement).
  • CAEPIPE displays units for each item on the screen. You do not have to search for it on different screens as in some other programs. See example screen shot below.
    • caepipe section dialog box showing data in All English format
  • Locate nodes in the model in an instant by using the search node feature.
  • Built-in SIF components libraries from ASME B31.x, ASME Section III, European EN and other international codes. User-SIF: Apply your own Stress Intensification Factor to override internally calculated SIF.
  • Option to internally compute SIFs and Flexibility Factors (FFs) for ASME B31 pipe fittings using ASME B31J.
  • Non-linearities. Model gaps using limit stops (such as in pipe slide/shoe assemblies), including friction at supports and expansion joints.
  • Ability to model supports connected to other nodes of the same piping system.
  • Flange report (allowable flange pressure and gasket diameter required).
  • Lists of components/fittings/supports such as bends, hangers, reducers, anchors etc. for quick review and editing.

Simple and Elegant User Interface

CAEPIPE has a well-designed user interface with drop down menus and descriptive dialog boxes that make for efficient modeling sessions.

Full Mouse Support - The Way You Expect

Full mouse support is provided in text and graphics screens. Just point and click on an element to edit its data. If you are a keyboard user, shortcuts are aplenty.

Interactive Graphics - Intuitive, Clean and Stunning

Pan, zoom, rotate, change viewpoints and more. Ideal in a two display unit system, CAEPIPE graphics can be on one and the text screens could be on the other, just like in an expensive CAD system.

Graphics Highlighting

Use this feature to pinpoint any component, view branch lines only, or view lines subject to a specific pressure/temperature.

Block Operations

Change material, temperature, pressure, pipe size and friction coefficient for a range of elements. Generate copies of existing pipelines in an instant with simultaneous graphics update. Rotate a whole or a part of a model about any axis in one operation. Add slope to a whole pipe run, and more.

Simultaneous Error Checking

CAEPIPE detects errors as they occur on the input screen (some programs report errors after you exit the input module).

Units in Combination

CAEPIPE allows you to keep all units in Metric or English or SI. You can customize each item (pressure, stiffness etc.) to have different units.
