EDLON

FLUOROPOLYMER LININGS

Edlon offers custom loose linings fabricated from Teflon® PTFE, FEP, and PFA in thicknesses ranging from 60 to 180 mils.  They provide unsurpassed resistance to corrosion and permeation even in severe chemical environments at  temperatures up to 400F.  Additionally, their smooth interior surfaces provide excellent release properties for reduced material build-up.  Liners can be vacuum formed to accomodate dished vessel heads and more complex shapes.  Loose linings can be fabricated to fit inside plastic, fiberglass, and steel or metal alloy structures including:

  • Columns

  • Pressure vessels

  • Storage tanks

  • Vessel covers

  • Heat exchanger shells

  • Transport tanks

Edlon's custom loose liners are inert to most chemicals, except for molten alkali metals and certain halogens or halogenated compounds at elevated temperatures.  Our loose linings are successful in a wide range of chemical services including, caustics, acids, and organics.  Edlon's loose linings are field-repairable; our trained technicians can make on-site repairs or provide field repair training.

Advantages of a loose liner:

  • Fusion welded seams. Wherever possible Edlon's loose liners are fabricated using 100% PureFusion™ welded seams. This results in seams with tensile and elongation properties equal to the virgin film. This valuable technique is unrivaled in the industry.

  • Low fabrication cost.

  • High temperature rating. Loose liners offer the best performance at elevated temperatures, higher either than coatings or bonded liners. Edlon is also able to offer a "low-stress" design for loose liners. At elevated temperatures, this variation on a loose liner offers higher resistance to stress cracking than any other liner.

To accomodate services that will involve agitation or vacuum, Edlon offers vacuum cage assemblies and plastic-encapsulated steel rings to secure a loose liner in place.  As an alternative to these methods, Edlon also offers bonded liners in 6 different fluoropolymers.
