Pickling lines for black steel pipes of all diameters and lengths

KVK Koerner pickling lines offer an efficient solution for the surface treatment and passivation of steel tubes.

KVK Koerner is a leader in the development of pickling lines optimised for the treatment of black steel tubes. Our systems use state-of-the-art technology to clean the surfaces of these pipes of oxides and other impurities, making them ideally prepared for further processing steps.

Technology and design

KVK pickling lines for black steel tubes are technically similar to our established hot-dip galvanising lines, but specially adapted to the requirements of black steel processing. An efficient crane and exhaust air system enables safe and precise handling of the tubes during the entire pickling process.

From pre-treatment to finishing

The pickling lines for black steel tubes are designed for continuous processes, even at high temperatures, and support various process steps such as degreasing, pickling, activating, phosphating, neutralising and soaping. The encapsulated pre-treatment protects the system components from corrosion.

Safety and environmental standards

The closed systems of our plants minimise the emission of hazardous vapours and thus contribute to an improved working environment and lower environmental impact. All systems comply with the strictest safety and environmental standards and offer comprehensive protection for all system components and, of course, your personnel.
