SOLUTIONS

Reliable analysis
for complex systems

SIGMA solutions support the design and verification of piping systems, interconnected networks and pressure components. The different tools cover static and dynamic analysis, finite element calculations, fluid flow simulation and code-based verification within a coordinated workflow.

The software range enables companies to:

  • analyse stresses and deformation in piping systems;
  • evaluate static, dynamic and seismic loads;
  • investigate the behaviour of critical components and local areas;
  • calculate flow rates, pressure and heat loss in piping networks;
  • verify pressure components according to major international standards;
  • document results through reports and graphical representations.

3Units combines software expertise with specialist skills in analysis engineering, providing support with tool configuration, engineering calculations and interpretation of results.
