RF-PIPING Add-on Module for RFEM
Modeling Piping Systems
The RF‑PIPING module is an extension of the RFEM user interface that allows modeling and loading piping systems conforming to standards.
It is possible to define specific piping components (pipes, fittings, flanges, valves, expansion joints, etc.) affecting the calculation. Furthermore, integration in RFEM facilitates the interaction between a supporting structure and the piping. By this and by considering the flexibility of the supporting structure in piping systems, realistic piping design is possible.
The module provides the basis for piping design in the RF‑PIPING Design add‑on module.
- Graphical input of piping systems and piping components
- Illustrative visualization of piping systems and piping components in RFEM graphic window
- Comprehensive libraries for piping cross‑sections and materials
- Comprehensive libraries for flanges, reducers, tees, and expansion joints
- Consideration of piping structure (insulation, lining, tin‑plate)
- Automatic calculation of stress intensification factors and flexibility factors
- Specific piping action categories for load cases
- Optional automatic combinatorics of load cases
- Consideration of material properties (modulus of elasticity, coefficient of thermal expansion) either during operating temperature (default option) or during reference (assembly) temperature of material
- Consideration of elongation and straightening due to pressure (Bourdon effect)
- Interaction between the supporting structure and the piping system
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.

- Is it possible to analyze and design piping systems in RFEM?
- Why is not possible to load the OPE combinations in the RF‑PIPING Design add-on module?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
- I would like to create a ring pipeline consisting of several parts. How do I prevent the transitions from being connected?
- Is it possible to use RFEM for modeling a channel that is distorted from a rectangular cross-section to a pipe cross-section?
- I use rotated surfaces in my model. Now it takes a long time to open and edit the file. What can I do about it?
- I have calculated a box beam. Which surface results or surface stresses can I use to evaluate the buckling behavior of the web plates?
- Where can I find the internal forces at certain nodes in the printout report?
