Pressure vessels are closed tanks whose pressure inside is higher than the ambient pressure.
Here, computational proof is often provided following the AD datasheets.
Often, simple analytical methods or simplified FEM calculations are suffcient for such analyses

Merkle & Partner focusses on the calculation of more complex
tanks which no longer can be calculated with simplified methods.
Here, FE models of any geometry are applied.
Proof can also be provided with non-linear behaviour, plasticity
of the material, non-homogeneous temperature etc.
The resulting deformations and stresses can be analyzed
according to all current standards and regulations (AD2000,
ASME, KTA, EuroCode et al.).
Tank construction, heat exchangers, filters, pumps
Determination of the test pressure pump housings can withstand
at a maximum, flange analysis and analyses of foot connections
of pressure vessels, filters etc. of any geometry, calculation of heat
exchangers.
