“You can count on us…”

More than 30 years experience with (strength) calculations in steam boiler, tank and pipeline construction

Based on this wealth of experience, which cannot be materially quantified, we are happy to support you with structural-mechanical consulting and calculation services for


  • Utility steam generators
  • Waste incineration steam generators
  • Coal gasification plants
  • Waste heat boilers
  • Chemical plants
  • Nuclear facilities and components
  • A.o.th.

We analyse and evaluate(!) the stresses and strains for

  • cold or hot
  • stationary, non-stationary and/or cyclic
  • in the low or high pressure range

operated components

  • according to national and international regulations like
    • ANSI B31.1, ANSI B31.3
    • EN12952, EN13445, EN13480, EN1591,
    • AD2000, TRD u.a.
    • British Standard PD5500
    • Stoomwezen
  • with analytical and numerical structural analyses of
    • mechanical and / or
    • thermal stresses of the above mentioned components

Selected services include:

  • Stress analyses for strength verification
  • Stability checks (buckling, dents)
  • Proof of stability
  • Temperature field calculations
  • Thermal stress calculations
  • Fatigue check for the low and high cycle range to determine
    • the fatigue strength
    • permissible load change
    • permissible cold and warm starts
    • Remaining service life
    • Creep fatigue damage in the high temperature range
  • Creep rupture strength verifications to determine
    • the creep and relaxation behaviour
    • permitted operating times
    • Remaining service life
    • Creep damage
    • Creep Fatigue Damage
  • Deformation analyses
  • Stiffness checks
  • Analysis of the vibration behaviour (modal/time history)
  • Support in the selection of materials
  • Variant calculations and optimizations
  • Preparation of auditable records and documentation
  • Support during appraisal interviews / approval and preliminary testing (e.g. TÜV acceptance, ASME Inspectors, Professional Engineers …)

What we calculated for our customers, you can see in our reference list.

(Unfortunately, we are not allowed to publish the most interesting projects due to blocking notices of our customers. Data protection and confidentiality are a matter of course for us)

We will not leave you alone with colourful pictures !

If our customers wish, we accompany a component continuously in an advisory and calculating capacity during

  • the sales process
  • project planning, development and optimization
  • the construction
  • the production
  • the assembly
  • the transport
  • the pressure test
  • the commissioning and
  • the analysis of damage claims

and advise you on

  • Permits and
  • Expert opinion
    Therefore we are more than just a calculation office!

Note: Gender-sensitive language is important to us. Therefore, we use gender-neutral terms on this portal whenever possible. In addition, we use the generic masculine. This explicitly refers to all genders (m/f/d). This procedure is for editorial reasons only and does not imply any kind of judgement.
