STATE-OF-THE-ART ENGINEERING
Design & Calculation of Bellows

Our experience and broad product range enable us to provide high quality solutions and services for the benefit of our customers.
All expansion joints (also known as Bellows) are engineered specifically to suit the customers project and to solve the expansion problem.

To meet the expectations of high safety, engineering must be supported by reliable and verified calculations. We calculate therefore according to the latest design codes, recognised by international classification associations. The required solutions can be supplied with CE-marking in compliance with the Pressure Equipment Directive (2014/68/EC).

Our design process of Bellows includes the following:

  • Design standards: EN 13445, EN 13480, EN 14917, PED 2014/68/EC, ASME VIII, Div. I, ASME B31.3, ASME B31.1, AD 2000 or EJMA
  • CAD Drawings
  • 3D Modelling of Bellows
  • Finite Element Analysis (FEA)
  • Technical consulting on optimal solutions in regards to Bellows design, application, locations in the pipe system and installation requirements.
  • Calculation software: BelMaker®, OMTECH and ANSYS

VALIDATION OF BELLOWS DESIGN

In certain situations, it is not immediately possible to validate the pressurised integrity of a Bellows construction by means of the analytical formulas specified in the applied design standards. For example, the geometrical complexity of the Bellows construction or the need for a further optimisation of the design could mean that the analytical formulas cannot be applied. In such situations, Belman can verify the integrity of the Bellows construction by means of complex Finite Element Analyses.

For this purpose, we use ANSYS® and the validation is carried out according to the terms of the specified design standard. The results of the analysis are often used internally for optimisation of the Bellows construction, but as an additional service Belman can prepare an evaluation report as part of the technical documentation package.

The software used by Belman is tested and validated through close co-operation with reputable institutions such as DNV-GL and TÜV who also use this software regionally.
