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).

DESIGN
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.
OUR RESPONSIVENESS, YOUR BENEFIT
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.

QHSE
The focus on quality has always been a central part of the Belman’s mission. We strive to provide services of consistently high quality that fully meet the expectations of our customers. Implementation and adherence to recognised quality assurance systems ensures that all processes have been accurately performed – starting from the initial review of the submitted specifications to their design, manufacturing, testing and documentation in accordance with the customers’ requirements. The accreditations and certificates we possess enable us to shorten lead times and optimise resources by performing testing and inspection procedures in-house.

DOCUMENTATION
Not only does Belman concentrate on the quality and finish of its Bellows, the same careful attention is also applied to the associated documentation.
Belman has developed its own special software which manages the material traceability on each project. It is also integrated with our design software to ensure the integrity of all materials used against the design code. Documentation is provided with every project. As we are able to execute tests and inspections in-house, our documentation is generated quickly and depending on the client’s request, documentation can be supplied with the Bellows or sent separately. This ability to quickly generate documents ensures that no time is lost when our Bellows arrive at the destination, allowing the installation to be immediately executed with the absolute minimum downtime.
Due to our strength in document management, we are repeatedly chosen by clients. For our Bellows and customised solutions, we can provide the complete documentation packages for the Bellows needed. Documentary requirements are determined by the project specifications, the application and the customer, industry and design code.
Some Bellows projects require just a few certificates while other Bellows projects, such as those for e.g. the nuclear power industry, require thousands of pages of documentation. No matter what the requirements may be, Belman has the experience to ensure compliance.
This documentation for Bellows includes among others:
- Calculations
As standard we provide Bellows calculations and, in addition to that, we can provide calculations on all other parts of the Bellows via various methods like stress analysis (FEA) etc.
- Welding documentation
According to 15600 series (PED), AD 2000, ASME IX and welding qualifications such as EN/ISO 9606, EN/ISO 14732, AD2000, ASME IX. - Other documentation
We provide any other documentation for Bellows such as: Inspection certificate, material certificates according to EN 10204 3.1, DoC – Declaration of Conformity, CoC – Certificate of Conformity,
ITP – Inspection and Test Plan, measuring report, paint report incl. data sheets etc. - 3rd Party authorities:
We cooperate with many 3rd parties like; Lloyds register, RINA, CCS, Bureau Veritas and many others.
