How does a product material prove its quality?
We examine the chemical, mechanical and thermal properties of product materials using state-of-the-art techniques in order to make our products more robust and durable.
Because our products are installed for decades, selecting the best possible product materials is absolutely decisive for product quality. Thermoplastics, which offer virtually endless moulding and colouring possibilities, are particularly well suited for cisterns and pipes. The plastic granules are available in off-the-shelve quality or are adapted to our needs. However, we also develop plastics in our laboratories according to our own formulations. All product materials used undergo intensive testing and checks in a process that involves inspecting their long-term properties using state-of-the-art techniques.
Drinking water pipes, for example, have to meet very strict approval criteria in order to receive the corresponding approval mark from regional authorities. Fatigue tests are carried out as part of this process. Here, the product materials and pipes are subjected to above-average stress, such as a high dose of chlorine, hot water up to 95 °C or excessive internal pressure. Only after these and all other tests are passed is the product ready for industrial series production – and ready for use in the various building types.
