A smart flange system for increased safety

The QVF Supra-Line is compatible with two proven flange systems — the QVF/WPR2002 and the Schott/KF systems — and thus reduces the number of technically equivalent components required while providing the user with increased safety. The Supra-Line extends the allowable operating conditions for temperatures up to 200°C, provides extensive resistance to acids and solvents, and an even higher corrosion resistance due to its fire-polished flanges. The Supra-Line flanges in the nominal size range from DN 15 to 300 require only one seal per nominal diameter, regardless of the shape of the flange. The flange connection features a patented clamping system with a ringed grounding element within the groove of the flange instead of screwed-on lugs. — De Dietrich Process Systems GmbH, Mainz, Germany
