Some clients who choose AutoPIPE for their projects

Main Features

  • Static and dynamic analysis
  • 30 static seismic acceleration and 10 wind cases.
  • Multiple dynamic analysis in a single run.
  • Work using piping specifications to avoid multiple pipe properties reentry
  • Integrated Water Hammer calculator to easy setup a Time History Dynamic Analysis Set.

Plastic, Duplex and Stainless Steel pipes

Desalination plants combine Fiber Glass Reinforced Pipe (GRP), Polyethylene (PE), Carbon Steel (CS), duplex and stainless steel pipes. Combine as many materials as you need in one model and easily model accessories and see their properties and thickness at a glance.

Use B31.3 or EN 13480 for the carbon steel, stainless steel, duplex and Polyethylene pipes and ISO 14692 or BS 7159 for the GRP (Polyester or Epoxy); and, as always, change between them with a click of the mouse.See+

Using Pipe Specifications

All the low pressure pipes (normally below 16 barg) are built using GRP pipes. GRP properties depend on size and whether it is a pipe or a fitting. Pipe types and fittings have different thicknesses and generally tees are fittings especially thicker to compensate for the SIF. In many programs, users must manually change these values each time the properties change, requiring many man hours of work.

In AutoPIPE specifications for pipes and fittings are input once and reused as often as needed. This centralization of data allows to apply changes and updates in a matter of seconds.

In some projects, not only are the material properties of the fittings are different, but every diameter has its own elastic modules and Poisson's ratio. In those cases, it is best to define the specifications in a seed model and use them in all GRP calculations.

Each color represent a different pipe specification. This View allow a fast verification of the pipe specification
Complex water hammer can be imported from any hydraulic calculation software and evaluated in AutoPIPE

Water Hammer

Easily calculate forces and stresses in the event of sudden valve closure. AutoPIPE prepares the Time History of the forces in each elbow or imports them from other programs to perform dynamic integration of the time history profiles.


If your facility is partially or fully submerged or is susceptible to flooding, whether in testing, commissioning or operation, you MUST perform a flotation study to ensure that your system continues to function after the event and does not float on water. See+

User just have to define the elevation of the water under the flood and the program will calculate the buoyancy load as a distributed load.

Buried Pipe

Without having to create another model, quickly bury sections of it by taking advantage of the automatic soil calculator. Study the influence of soil type by creating more than one Set. Place your concrete anchor in the simplest way: defining the size using a rigid pipe and one single anchor on the center. AutoPIPE can analyze 3 soil models at the same time.

AutoPIPE analyzes the pipe-soil interaction cpnsidering the settlement by weight and surface overloads. Easily visualize the deformed or study the stress envelope with a color code.

For the big GRP pipes, settlement when filled-water pipes can produce high loads and stress. Settlement must not be ignored, although many programs dismiss densities in the buried sections and thus its settlement effect. See+

The areas in purple represent the size of the concrete block. In eack block one anchor has been defined.

Larger Models

Thanks to AutoPIPE high convergence engine, you can use models as large as you need them to be. Save time and save money by the consequent reduction of number of anchors or the time-consuming alternative of transferring displacements from various models.

Tip: Import the geometry form the 3D model, apply the pipe specifications and use the graphical Copy and Paste to quickly duplicate similar piping arrangement.
