B-4
Styles 204 and 204HP
Styles 204 and 204HP spool-type expansion joints
can be constructed as single- or multiple-arch types.
They connect pipe fanges in concentric or eccentric
tapers, to join piping of unequal diameters.
Benefts
¦
Fully lab- and feld-tested for long life and excep-
tional reliability
¦
Seamless fange face eliminates need for gaskets
¦
High pressure- and vacuum-resistance increases
safety and ensures suitability for wide range of ap-
plications
¦
Can be custom-designed for greater movement
capability and easier installation
¦
Variety of elastomer and fabric combinations meet
the demands of temperature, pressure and media
Design
¦
Tube
• Chlorobutyl resists cracking due to high tempera-
tures, weathering, oxidation and chemicals
• Abrupt arch confguration provides maximum
movement, and pressure and vacuum resistance
• Seamless tube creates a positive fange seal
without gaskets
