Specialised materials, processing and welding know-how

Summary: For cost reasons, chemicals, pharmaceuticals, biochemicals and waste-gas treatment equipment is frequently fabricated from glass-fibre-reinforced plastics (GRPs). Where they handle aggressive chemicals, they may also need extra protection in the form of especially resistant linings. This article examines a Swiss specialist’s approach to such a task, focusing on the example of a flue-gas quench for a waste-incineration plant.
