Koerner has more than 25 years of experience and research, worldwide patents, and customers in 50 countries worldwide.
The pickling line in the Paderborn plant of one of the most important pipe manufacturers in Europe - the Benteler Group – was expanded considerably in 2005.
Four 16 m long pickling tanks for sulphuric acid up to 60°C and an acid-proof KVK Laminate® coating, certified by TÜV to comply with the German Water Resources Act (WHG), has met all requirements for more than 7 years.
The exhaust air is extracted around the clock by a "push-pull system" directly from the baths and scrubbed of the sulphuric acid aerosols in a two-stage separator. In the process, permanent monitoring keeps an eye on all the relevant process parameters.
