Lining metal tanks, pipes with ETFE keeps corrosion at bay

AGC Chemicals Americas Inc. announced that its Fluon ETFE powders are ideal for seamless rotolining of industrial equipment used in chemical processing applications in the food, petroleum and potable water/wastewater industries. Rotolining vessels with ETFE is reportedly superior to tradition sheet lining methods because the free-flowing ETFE powder naturally conforms to interiors and does not typically require welding and sealing.

The Fluon ETFE is a melt-processable copolymer of tetrafluoroethylene and ethylene. Fluon ETFE powders provide outstanding physical properties that include toughness and high resistance to heat and chemicals, and superior corrosion protection.

The rotolining process requires heating the tanks, valves pipes, pumps and other vessels into which the powder is poured. The vessels, tanks, etc. are then heated and rotated while the ETFE coats the insides of the vessels and tanks, much like a typical rotation process, a company spokesperson said.

Fluon ETFE powders provide excellent bonding to metal and a seamless interior lining of intricate and complex objects, such as valves and pumps, with a uniform desired thickness. Additionally the Fluon ETFE powders can conform to the interior of virtually any size and shape vessel and can provide a lining thickness of up to 0.250." The rotolining process is mold-free, thus reducing mold and tooling costs.
