PTFE support grid
Support grids are used to hold the mass transfer packing in place. They are available either in the form of interlocking PTFE supports, or as PTFE-lined metal tubes.
The support grid is entirely made of PTFE in various thicknesses, according to the maximum diameter and taper allowed. The support grid is also available in PTFE-lined Hastelloy steel. The grid is directly supported by the support ring. In alternative, it can be clamped between flanges.
