Find and identify causes
For metal gaskets, particularly weld-ring gaskets, damage frequently occurs in the form of cracks. By investigating the microstructure of metal materials, we can draw conclusions about the manufacturing processes or thermal treatment, or the physical and chemical properties. To limit the causes of crack formation or to evaluate the quality of a welds, we make use of qualified and accredited test labs from our area. As part of the investigation, we forward the damaged parts to the relevant labs and organise the handling of the investigations from the taking of samples right up to the coordinated test report.
We carry out more minor investigations such as hardness measurements or topological investigations of damaged sealing elements and surfaces in our own labs.
