Protective linings in reactors and tanks fabricated with fluorinated plastics (Halar® ECTFE, Hylar® PVDF, Hyflon® MFA/PFA, Algoflon® PTFE) provide excellent resistance to extreme chemicals and temperatures. Depending on the size and geometry of the part, the corrosion-resistant lining is applied by powder coating, sheet lining, extruded lining, rotational lining or FRP dual laminate. Dual laminate construction, employing a variety of fluoropolymers as an integral component to the fiber reinforced plastic (FRP), is available for large diameter pipe, scrubbing towers, and even in pressure-rated reaction vessels.
Fluoropolymer lining systems are an alternative method to using specialty alloys such as stainless steel, titanium, Inconel® or Hastelloy® for corrosion control purposes. Significant cost savings can be achieved and a reliable system specified by appropriate selection and application of fluoropolymer lining systems.
Fluoropolymer coating and lining technology gives designers more flexibility. For example, seamless powder coatings allow for corrosion protection of any design that can be fabricated in metal. Their only limitation is oven size. Currently, ovens as large as 40 ft x 15 ft x 12 ft are in operation. Other product forms such as sheet linings can be applied in the field to large vessels and over-the-road trailers.
Halar ECTFE, Hylar PVDF, Hyflon MFA/PFA, and Algoflon PTFE fluoropolymers are used as continuous linings within FRP dual laminate or steel substrates. Extruded liners can be pulled into steel pipe or over-wrapped with FRP in a dual laminate construction.
Thicker linings provide much better protection against permeation and abrasion. These linings can be applied through rotomolding, as found in most pumps, valves and fittings, or through sheet lining. The latter process may be a loose liner as in many PTFE applications or may use adhesives to bind the fluoropolymer to a surface.
