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.
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.

Load Combinations for Pipe Stresses due to Occasional Loads
The add-on modules RF-PIPING and RF-PIPING Design allow you to design piping systems according to EN 13480-3 [1], ASME B31.1 and B31.3. In the case of the European standard, the determination of pipe stresses is based on the formulas of Section 12.3 Flexibility analysis. Depending on the stress type, one or more resulting moments is applied without regard to each other. This differentiation occurs when determining the stresses due to occasional loads, for example.

Automatic Load Combination
Like in RFEM, load combinations can be automatically generated in RF‑PIPING. This feature is activated by default and creates the recommended load and result combinations for piping design. It is necessary to assign the relevant action category to load cases in order to generate correct combinations. For this, there are new action categories implemented specifically for loads on piping.
