6 Das Schweißen erfolgt unter Vollschutz. Unten der elastische Ring, der die Auskleidung andrückt, oben zwei Stabilisierungskragen an den Stutzen • Welding is performed wearing a full-body welding suit. The flexible ring, which thrusts the lining against the wall, is seen at bottom, and two stabilisation collars on the sockets at top

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.

Since private consumers generally have neither sufficient knowledge nor the necessary discipline to keep hazardous and/or environmentally harmful substances out of the waste flow, a chaotic mix, containing virtually all possible ingredients, is what lands in the incineration furnaces. “Cleaning of waste gases from waste-incineration plants is a particularly demanding task, because you find here virtually all the conceivable hazardous and toxic substances”, comments Serge Naegelin, Head of Sales, Technology in Plastics - Dampers/Butterfly Valves, at Angenstein AG, of Aesch/Switzerland.
