Add-on Modules - Piping Systems
RF-PIPING is used to model pipelines and to define the 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.
The RF‑PIPING Design add‑on module compares the existing pipe stresses with the allowable stresses according to EN 13480‑3, ASME B31.1, and ASME B31.3.
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.
- How do I change the default settings for the units so they are preset in every new file?
- How can I quickly delete the unused elements (for example, cross-sections) from my model with one click?
In the case of stairs with a complicated geometry, it is often difficult to design welds by using the analytical methods. How can I do this with RFEM?
- How do I activate pipeline modeling?
- I have calculated a box girder. Which surface results or surface stresses can I use to evaluate the buckling behavior of the web plates?
- Is it possible to analyze and design piping systems in RFEM?
- 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?
