ADVANCED EXPANSION JOINT

DESIGN
& ENGINEERING

Belman expertly engineer customised Expansion Joints using state-of-the-art design, analysis and modification principles. 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 client’s 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 societies. The required solutions can be supplied with CE-marking in compliance with the Pressure Equipment Directive (2014/68/EC).

High tech Expansion Joint Solutions

The high-tech solutions are supported by:

  • Detailed quotations showing all relevant data
  • Specifications on of the Expansion Joint
  • CAD Drawing
  • 3D models (in STP format)

HOW WE DO

EXPANSION JOINT ENGINEERING

The Bellows solutions are developed in accordance with the submitted specifications and in close interaction with our clients, producing results which offer the optimal balance between performance and cost. We pride ourselves on the fast response to customer requests, especially in critical situations that call for the urgent replacement of Bellows.

ENSURING THE RIGHT SOLUTION

DESIGN VERIFICATION

In certain situations, it is not immediately possible to validate the pressurised integrity of an expansion joint construction by means of the analytical formulas specified in the applied design standards. For example, the geometrical complexity of the expansion joint 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 expansion joint 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 Expansion Joint 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 and TÜV who also use this software regionally.
