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.

  1. Wall Thickness Allowances in RF-PIPING

    Wall Thickness Allowances

    Piping stress analysis requires a calculated wall thickness to be set. This does not always correspond with the wall thickness of the imported pipe cross‑section. So you can define allowances due to abrasion, corrosion, manufacturing, and potentially threads, if necessary. The respective thicknesses of c0, c1 and c2 can be defined in the ‘Stress Analysis Parameters’ tab.

  2. Automatic Load Combination in RF-PIPING

    Automatic Load Combination

    Like in RFEM, automatic combination of load cases is also available in RF‑PIPING. This feature is activated by default and creates the required piping and result combinations for design. It is necessary to assign the load cases to the relevant action category. For this, there are new categories implemented specifically for pipeline construction.
