PLC-controlled pickling system for long stainless steel tubes

Braunschweig/Germany, 23 October 2018 – A true novelty debuts at the international sheet metal working exhibition EuroBLECH: The German company Siedentop GmbH presents a pioneering pickling system for long stainless steel tubes that may be installed without prior legal approval in most countries. It is a cost-effective alternative to conventional tube pickling and offers resource-saving and fast pickling processes.

The fully automated tube pickling system Tube Blue Rotainer is built as closed container system. It uses nozzles to spray bath pickling acid on the tubes. A hoist-rotation lift specially designed for tube pickling brings the tube bundle to be pickled to an optimal position, ensuring that all tubes are uniformly coated with the bath pickling solution. The tubes within individual bundles may have different diameters.

As the Tube Blue Rotainer can be operated with less than 1,000 litres of pickle, companies in most countries needn’t ask for legal authorization to install the system. “Depending on the country, legal approval procedures may take up to several months,” reports Friedrich-Werner Siedentop, founder and managing director of Siedentop GmbH. “However, when facing harsh competition, a business can’t put an investment on hold for so long. With the Tube Blue Rotainer, you can immediately take action and start planning the start-up of your pickling unit.”

Siedentop will showcase the Tube Blue Rotainer at the EuroBLECH exhibition in hall 13 on booth H141. EuroBLECH will be held from 23 to 26 October 2018 in Hanover/Germany. It is the world’s largest exhibition for the sheet metal working industry.
