Qualification and product validation
Our project teams, working in accordance with the project management procedures and responsibilities defined in our management system, ensure that customers' requirements in the specifications are translated into detailed technical specifications.
A number of systematically applied quality methods and quality assurance tasks and tests in product development ensure timely product realization in conformity with quality requirements. For this purpose, various tools and means are deployed at all stages of product development—for personnel, equipment, simulation, and testing, for example:
At the design and tender preparation stage:
- Risk analysis
- Potential design failure mode and effect analysis (FMEA)
- Computer-aided heat exchanger and equipment design
At the order processing and industrialization stage:
- Design and process FMEA
- Simulation: FEM test
- Simulation: CFD test
At the product verification and validation stage:
- Temperature change tests
- Pressure change tests, bursting pressure tests
- Performance and functional tests
- Vibration tests
- Strength tests (stress and extension measurements)
- Noise measurements
- Materials laboratory tests (see annex for material test procedures and devices)
- Corrosion test
