Strength and load analysis

Boilers, pipe systems and systems

All stress and strength analyzes for process engineering systems and their system components, in particular pipe systems, pressure vessels, boilers and piping technology, are carried out in accordance with recognized technical regulations. INTEC evaluates the data from the static, dynamic and non-linear thermo-physical simulation and considers vibration, pressure and natural frequency ranges.

 

INTEC carries out a strength verifications for the internal and external pressure, including the strength verifications of flanges and the stability verifications for the components.

We prepare the strength calculations according to the standard standards EN13480, EN13445, AD Merkblatt 2000 as well as ASME VIII sec. 1 and sec. 2, as well as the calculations using the finite element method.

INTEC carries out the following stress analyzes (BA):

  • BA from internal and external overpressure,
  • BA from the external load on the nozzles and shells,
  • Fatigue analysis including remaining service life analysis,
  • BCalculation of dynamic loads such as earthquakes and wind,
  • Determination of tightening torques and
  • Checking supports and anchoring of containers, etc.

The complete analysis includes stress analyses for pipe systems, determination of support and connection loads, including component connections, calculation of the strength of pipelines taking into account displacements and boundary conditions. The calculations are carried out using Rohr2 software.

The load cases for

  • Own weight, overpressure
  • Pressure testing and assembly
  • Expansion, wind and earthquake

All strength calculations for pressure vessels are carried out in accordance with the standard norms EN 12952, EN 13445, ASME I, ASME VIII, PD 5500, AD Merkblatt 2000, FDBR standards and CODAP.

INTEC prepares the strength calculations in accordance with the standard norms EN 13480, EN 13445, AD Merkblatt 2000 and ASME VIII Sec. 1 and Sec. 2 and carries out the strength verification for internal and external pressure, flange connections and supports.

INTEC prepares the load analyses for:

  • Internal and external overpressure
  • Loading of the nozzles and flange connections
  • Fatigue and remaining service life
  • Dynamic loads such as earthquakes and wind

We use Rohr2 and PROBAT software for our calculations.

INTEC calculates deformations and stresses in process engineering systems using multi-physical simulation and checks the natural frequencies of the structure and the stability of the system components, taking static and dynamic loads into account.

The calculations are based on the following standards:

  • EN 1991: Actions on structures
  • EN 1993: Design and construction of steel structures
  • EN 1998: Design of structures against earthquakes
