Balancing even large unevennesses of Glass-Lined-Steel-Flange seal surfaces The new Generation of Sealing Technology for enameled flanges and flanges with major form deviations Sealing concept The individual thickness of the 3D - Logic Seal - Sealing in its circumferential direction exactly follows the line of the minimal unevenness and gap between the two sealing surfaces in radial and circular direction. The Illustration below shows the principle of a dimensioned unevenness of a flange and its developed view. In the circumferential direction the seal exactly follows the asperities of the surfaces. In radial direction the 3D - Logic Seal - Sealing has the same thickness over the entire seal width - leading to line contact over the complete periphery. Exactly reproducing the form of the seal face would lead to a big surface - meaning low surface pressure - which is explicitly not wanted in the sealing technology. Due to the line contact of the flange surface to the seal surface, even with very low bolt force, a considerably high surface pressure is achieved. Data entry of the flange surfaces After scanning the unevenness of the seal surfaces with 3D-scanners all data are recorded with an especially developed monitoring procedure, and then calculated and finally displayed. Scannen der Flanschoberflächen Scanning the flange surfaces Photooptische Erfassung Photo-optic recording This procedure allows to precisely measure 2 flange surfaces to each other - whereas they are at different locations. The data are summarized and visually displayed in a 3D-CAD-Model as a flange pair, calculating the narrowest gap in the
