       PTFE / PFA Fluoropolymer Lined Columns


      CRP Specialise in the manufacture of Hiperfon® PTFE / PFA lined piping and ancillaries, we use high performance polymers manufactured by the leading fluoropolymer suppliers to provide the longest service life for lined products. Hiperflon® lined products are used in acid, caustic, fluorine and other highly corrosive applications, they are ideal for multipurpose plants.

      CRP manufacture lined absorption and distillation columns utilising a combination of Hiperflon® PTFE and PFA lined steel sections. The linings of each section are one piece having no seams or welds. The fluoropolymer linings are suitable for use in processes from -29° to +200° C.

      With liner thicknesses up to 9mm the column linings offer high permeation resistance and vacuum performance.  PFA already outperforms PTFE in resisting permeation and we can offer our modified UHP PTFE liners to provide the longest service life.  

      The column sections containing nozzles are produced in one piece utilising our PFA lining techniques overcoming problems with leaks associated with other multi-piece nozzle designs or those with welds within the linings. These sections can have multiple nozzles in any orientation around the periphery of the column.

      The end covers for the lid and base are again manufactured from one piece of steel work without any additional bolt on pieces, they have one piece PFA linings offering the best integrity.

      Columns are often designed with multiple bores and these can be provided using smooth transition reducing sections or reducing flanges.

      Columns can be provided with associated internals including packing support plates, support grids, liquid distributors. These are all supplied with thick PFA linings. 

      We can supply a full range of fully lined PTFE gas injectors, dip pipes and spargers to suit the customers process to compliment the column.

      Body:   P235TR2, P265GH, ASTM A106
      Flanges: S235JRG2, P250GH, ASTM A105
