Our POLYFLURON®-PTFE with wall thickness of up to 8 mm and lowest permeation / diffusion values serves for the lining of columns and vessels of a nominal diameter of up to DN2500.
Upon request, we also deliver, of course, our columns and vessels with all internals such as distributors, re-distributors, inlet pipes, support rings and grids as well as mass transfer packages.
Applications (examples):
- Washing processes
- Absorption
- Adsorption
- Liquid – liquid extraction
- Distillation / rectification processes
- Reactors also with PTFE agitators etc.
- Solution for vacuum operation with chemicals such as HF, HBr, H2SO4, HNO3, H3PO4, etc.
Nominal Diameters:
We manufacture columns in DIN and ANSI with diameters of 200 to 2500 mm.

Column Lengths:
Column sections are produced to a length of
6 m depending on the diameter.
Lining Wall Thickness:
POLYFLURON® - PTFE lining is available with wall thicknesses from 5.5 to 8.0 mm. The decision of the most suitable wall thickness is dependent on the media, the process parameters as well as the desired lifetime of the columns.
Internals:
Support grids, liquid distributor, inlet pipes, downcomers, demisters made of PTFE
Services:
- CAD design
- Consideration of seismic&wind loads
- Calculation according to AD2000, ASME Code, British Standard etc.
- Acceptance according to PED 97/23 EG, U-stamp and China Stamp
