This adapter ring made of PTFE-lined steel is used for sustaining PTFE support grids, perforated plates, caps, etc. It is assembled by means of selfcentering external bolts.

Support rings are generally used to support structured packing such as high performance packing in pipe Sections. Up to DN 300 nominal size they are made of selected quality PTFE. In larger nominal sizes PTFE-sheathed steel rings are used. These also act as a support flange for the column section. Support rings are clamped between the buttress end faces using longer bolts in the coupling. The rings have a bead on both faces, so that no additional gasket is required.

FLAT/TAPER END PLATES FOR PTFE LINED COLUMNS

The use of end plates is recommended for sealing the top and the bottom sides of columns. The connections are dimensioned according to 3G experience and to the equipment available. The bottom plates can be the taper or flat types.
