We have complete in-house engineering facilities. Thermal layout and special heat transfer calculations are performed and checked with in-house developed computer programs. For highly complex tasks, the gas flow and heat transfer are calculated by means of three-dimensional CFD models (computational fluid dynamics).

The pressure vessels and heat exchangers are calculated according to all national and international calculation regulations

In the case of critical parts, Finite Element Analyses are carried out.

  • Software: ANSYS
  • Modelling in 2-D and 3-D
  • Temperature distribution calculation
  • Stress calculation for mechanical and thermal loads (elastic and elastic-plastic)
  • Classification of stresses in primary, secondary and peak parts 
  • Stress and fatigues evaluation acc. to international design codes
  • Contact simulation
  • Stability analysis
  • Modal analysis (calculation of natural frequencies and mode shapes)

The flexibility of the tube systems, the resulting support loads and forces are calculated by a special software.  

  • Software: ROHR 2
  • Modelling of complex piping systems
  • Stress calculations for mechanical and thermal loads
  • Consideration of wind and seismic loads
  • Valuation of calculated stresses acc. to international piping codes
  • Determination of the support loads
  • Rating of spring hangers and supports

The performances of piping engineering include:

  • Material orders
  • Collision check
  • Flexibility calculations
  • Isometrics for the 3-dimensional bending of tubes
  • Construction and commissioning
