Selecting a polymer, copolymer or fluoropolymer liner for your plastic lined steel project has never been easier. At KEFCO we supply Polypropylene PP (copolymer), Kynar Flex® PVDF (copolymer), Halar® ECTFE (fluoropolymer), Tefzel ETFE (fluoropolymer), Teflon® PTFE, Teflon® PFA, and MFA. All linings are molded in place after the fitting is cast or fabricated. All products are warranted 100%.
Polypropylene is an excellent polymer with proven chemical resistance in a wide variety of applications. It has good mechanical properties and, unlike the homopolymers, has relatively good cold temperature impact resistance.
Kynar Flex® PVDF is a fluoropolymer with excellent resistance to most chemicals. It has good stability and is resistant to radiation, abrasion, cold temperature and stress cracking. Better than a homopolymer.
Halar® ECTFE, a fluoropolymer, has exceptional chemical and physical properties. It is a superior choice where permeation, mechanical stress, and abrasion are troublesome.
Tefzel® ETFE fluoropolymer with superior chemical and physical properties. It is recommended in high pressure, vacuum, or systems where cold flow and joint creep are a problem. We call Tefzel® the problem solver.
Teflon® PTFE is an excellent fluoropolymer, virtually inert to all chemicals. It possesses high temperature corrosion resistance to almost all chemicals except fluorine and alkali metals. Its non-stick properties minimize or eliminate residue build-up on pipe walls.
Teflon® PFA is a newer melt-processible resin with the same chemical resistance, but with mechanical strength superior to PTFE Teflon®. It can also be used at somewhat higher temperatures under the same conditions.
The most complete lining capability in the industry, offering any fitting configuration imaginable. Uniform plastic wall thickness guaranteed in fittings as well as in pipe. Warranteed 100%. We do not bend, stretch, blow, seam or distort our homogeneous linings in anyway. That's quality!. We're ISO 9002!
KEFCO's lined steel combines the corrosion resistance of plastic with the inherent strength of metal. Each piece of pipe or fitting is cycled from ambient temperature through its temperature range prior to shipment. Every pipe and fitting is spark tested with a minimum of 10,000 volts insuring lining continuity and system longevity once in service. That is quality!
As a service to our lined steel customers we offer a complete line of flange shields manufactured from single and multi-layered clear cloth for easy visibility or a colored cloth with a leak indicating patch. Teflon®, Polypropylene, Polyvinyl Chloride, Polyethylene, and Saran are stocked daily. Stainless and galvanized shields are available for high temperature, high pressure, or when conditions are unfavorable for cloth shields. Drain Shields, Shields for Fittings, Valve Shields, Expansion Joint Shields, Pipe Vent Covers, always stock at KEFCO. Take an offensive stance to hazardous leaks and spray-out
containment in the work place.

Handling acids, caustics or high-purity fluids demands the finest piping and fittings. Metallic pipe is subject to corrosion,
even mildly corrosive fluids can rapidly eat away its inner surface.
