BELLOWS ENGINEERING & QHSE

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).

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.

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.
