Calculation of Pipe Flexibility - Piping
Numerical Simulation for Your Industrial Piping Systems
Industrial piping is not just a network of pipes: it is a mechanical system subject to pressure, temperature, dead weight, earthquakes, and transient conditions. A poorly analyzed network leads to breaks, leaks, production shutdowns—or costly regulatory non-compliance during the acceptance phase.
DAES conducts comprehensive piping flexibility studies for the following sectors: nuclear, energy, oil & gas, chemicals, and process industries, using industry-standard software and current international codes.
Why should you entrust your piping design work to DAES?
DAES combines two areas of expertise that are rare in the Swiss market: proficiency in specialized piping software (PIPESTRESS, Aspect/Octave, ANSYS) and in-depth knowledge of nuclear and industrial codes (ASME III, RCC-M, RCC-MRx, ESPN, EN 13480). Our engineers use these tools on real-world projects—not just in training—which ensures reliable results and reports that are acceptable to project owners and safety authorities.
Our teams are ready to provide you with valuable technical support for your piping network design projects or to help you predict how these systems will behave under mechanical, thermal, and seismic loads. With extensive expertise in stress analysis and design codes—even for the most complex configurations—our specialized engineers will guide you with confidence. Our commitment encompasses :
- Evaluating the performance of your piping systems under actual operating conditions and optimizing their performance by adjusting the placement of supports, modifying materials or wall thicknesses, and revising the layout (for example, by optimizing expansion joints).
- Linking the results of the system analysis (beam elements) with a local finite element analysis, or even with a dynamic seismic analysis or a transient response analysis.
- Accounting for all types of stresses: dead weight, internal pressure, thermal expansion, as well as phenomena such as water hammer, guillotine failure, and thermal fatigue.
