Technical glass

Joining parts with KZ, PZ ends

Two types of flanges are used for jointing glass parts with endings KZ and PZ. The flanges are pulled over the glass end pieces. An underlying segment (ring, bead or spiral) is inserted into flanges and prevents a direct contact of flange with glass and also fills-in the pull-over space of the flange.

The flange joints are used for two basic groups of packing – soft (SA, rubber) and hard (PTFE). Complete joints are supplied without packing which should be ordered separately. Basic series of joints are composed of flanges made of surface-finished aluminum alloy. Temperature resistance of the flange joint depends on material of the underlying segment and packing.
Suitability of packing for certain media should be assessed on the basis of its corrosion resistance and exact knowledge of process conditions (temperature, pressure, concentration and/or other factors).
Flange joints with PTFE packing include springs providing for permanent tightness of the joint.
