EthyleneFlexijoint ®Expansion Bellows• Constructed from isostaticallymolded,virgin PTFE– Carefully controlled crystallinityyields long flex life and hightensile strength– No pigments, lubricants or additives• Uniform PTFE wall thickness– No thinning of the PTFE at theconvolution sidewall• Available from .5" to 42" diameters in2 through 12 convolutions• T-band support of both convolution rootand sidewall increases stability at higherworking pressures• Custom application and design engineeringEthylene,LLC

EthyleneStandard Flexijoint ®BellowsExpansionLimitlink ® Flexijoint• Prevents over-expansion of thejoint even when mating flangesare not “two-holed”Limitbolt Flexijoint• Conventional limit bolt designEthylene,LLC

EthyleneFluoropolymer-Lined Specialty FittingsSeamless fluoropolymer linersavailable for virtually any fitting,column section or large diameterpiping sectionConstructed from high-temperaturecorrosion resistant fluoropolymers:–Teflon ® PTFE–Teflon ® PFA– ETFE– PVDFStress-free and heavy-walled linershave integrally molded flare facesand nozzle branchesIdeal for high vacuum and hightemperature serviceFabricated to your exact dimensionsEthylene,LLC

EthyleneEthylarmor ®Dip TubesEthylene,LLC

Ethylene,LLCEthyleneEthylarmor ®Dip TubesCombine the high-temperature, near universalcorrosion resistance of Teflon ® PFTE with themechanical strength of an encapsulatedSchedule 80 carbon steel pipeIdeal for agitated reactorsVirtually eliminates heat-seal failure andresulting damage to a reactor’s glass liningOptional features available including:–Diverters– Extended Flares– Spargers– AGI Dip Tubes* Stainless steel and alloy dip tubes availableStress analysis available

Fluoropolymer Linings• Available in a variety offluoropolymers including:–PTFE– PFA–ECTFE-PVDF• Chemically resistant overa wide range of operatingtemperatures (cryogenicto 450° F (230° C)• Both bonded andloose liner constructionavailable• Less expensive thanexotic alloy metals• Impervious to mostchemicals• Less susceptible tocracking due totemperature cycles ordamage caused byphysical impact duringshipping and installationEthylene,LLC

Fluoropolymer Linings•PTFE– Chemically inert– Resistant to nearly all chemicals– Maximum service temperatureof 302° F (150° C)– Ideal for applications where anti-stickproperties are desired•PFA– Thermoplastic with similar chemicalresistant properties to PTFE– Maximum service temperatureof 302° F (150° C)– Less permeable than PTFE– Ideal for use with organic solvents andin high purity applications•PVDF– Thermoplastic– Maximum service temperature of212° F (100° C)– Lower cost alternative to PTFE orPFA in certain applications– Excellent in bromine service• Other lining materialsavailable include:– ECTFE–FEP– ETFEEthylene,LLC
