Pipe Stress Analysis Software
3D Finite Element Analysis and Design
Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
Wind Simulation & Wind Load Generation
Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
Modeling of Pipelines
RF‑PIPING can model pipelines and define loads conforming to relevant standards.
It is possible to define specific piping components such as valves, reducers, fittings, flanges, tees, expansion joints, and others, and consider them together with the supporting structure.
Piping Design and Pipe Stress Analysis
RF‑PIPING Design compares the existing pipe stresses with the allowable stresses according to EN 13480‑3, ASME B31.1 and ASME B31.3.
Dynamic Analysis of Vibrations and Seismic Design
For dynamic analysis of piping systems, there are various add‑modules available for determination of natural vibrations and mode shapes, forced vibration analysis and generation of equivalent lateral loads for earthquakes.

Pipes subjected to internal pressure
Piping systems are exposed to a variety of loads. One of the most decisive is the internal pressure. This article will therefore deal with the stresses and deformations resulting from a pure internal compression load in the pipe wall or for the pipe.Screenshots | Piping Systems

Working with RF-PIPING
After activating the RF‑PIPING add‑on module, a new toolbar is available in RFEM and the project navigator and tables are extended. Piping modeling is performed in a similar way as members. Pipe bends are defined by using tangents (straight pipe sections) and bend radius at the same time. Thus, it is easy to subsequently change bend parameters.
It is also possible to extend the piping subsequently by defining special components (expansion joints, valves, and others). The implemented libraries of structural components facilitate the definition.
Continuous pipe sections are defined as sets of piping systems. For piping loads, member loads are assigned to the respective load cases. The combination of loads is included in piping load combinations and result combinations. After the calculation, you can display deformations, member internal forces and support forces graphically or in tables.
Pipe stress analysis according to standards can then be performed in the RF‑PIPING Design add‑on module. You only need to select the relevant sets of piping systems and load situations.
