Diflon Technology specialises in PTFE applications. Diflon’s decadelong experience has allowed the company’s engineers to develop a complete production program for the delivery of PTFE-lined pipes, connections, flexible joints, expansion joints, columns and tanks, as well as machined PTFE components.


Tanksline columns and tanks can be employed in various processes,such as:

  • washing
  • destillation or rectification
  • absorption columns for Hcl/Hbr, etc.
  • liquid extraction
  • reactors
  • storage tanks.

Tanksline PTFE-lined columns and tanks

The demand for multi-purpose plants in the chemical and electronic industries, the latest pollution control standards, the excellent anticorrosive and non-stick properties of PTFE, combined with the positive experience accumulated over many years, have led Diflon Technology S.r.l. to publish this catalogue.


The application range of PTFE-lined columns is from -10°C to +200°C. However, under particularly harsh operating conditions such as those involving high and sudden pressure and temperature changes, or in case of special shapes, etc. these application limits become narrower. The maximum operating pressure is 6 bar; special engineering solutions must be studied for vacuum applications. The Tanksline PTFE lining is obtained from virgin materials which are then processed with particular techniques to guarantee high hydrophobicity and dimensional stability. The PTFE linings are available in thicknesses from 3 to 5 mm. The well-known non-stick properties of PTFE ensure high resistance to fouling and excellent cleanliness, as a result reducing or even eliminating downtimes. Columns and tanks are available in nominal diameters from DN 300 to 2000 in flanged sections up to 2 metres in height (depending on the DN), flat or taper end plates, welded or machined nozzles, alon with a range of PTFE internals such as distributors, supports, rings, diffusers, suction tubes, etc. This catalogue describes the Tanksline® standard components in full details. We strongly recommend the use of standard parts so as to limit the number of eventual spares in the customer’s inventory. In case of certified and tested equipment, the use of standard PTFE-lined components allows the repair of the lining without the need for testing the metal substrate again.


The DIFLON TECHNOLOGY offers to its customers accurate design services. Recommending the best product to meet any demand.
