About Krope Lining
Krope Lining GmbH & Co KG, based in Kerpen, specializes in the lining and coating of flow meters. The core manufacturing focus is PFA coating (perfluoroalkoxy polymers) using an extrusion process, in particular for magnetic-inductive flow measurement tubes in sizes from DN 3 to DN 300. Workpieces to be lined can be made of steel, cast iron or welded steel constructions; the plastic lining is positively anchored by welded perforated-plate or expanded-metal grid inserts as well as groove turnings on the flange diameter. In addition to the measurement tubes, the company also manufactures PFA-coated accessories such as angle rings, threaded adapters, joint flanges and intermediate rings. In addition, Krope Lining offers tool and machine engineering as well as the design and manufacture of its own tools. The PFA linings comply with food-law regulations under EU law, BGVO, LFGB and FDA and are used mainly in the food and chemical industries.
