Styles 204 and 204HP

nnnn

Styles 204 and 204HP spool-type expansion joints can

nnnn

be constructed as single or multiple arch types. They

nnnn

connect pipe flanges in concentric or eccentric tapers, to

nnnn

join piping of unequal diameters.

nnnn

Benefits

nnnn

■ Fully laboratory and field tested for long life and ex-

nnnn

ceptional reliability

nnnn

■ Seamless flange face eliminates need for gaskets

nnnn

■ High pressure and vacuum resistance increases safety

nnnn

and ensures suitability for wide range of applications

nnnn

■ Can be custom designed for greater movement capa-

nnnn

bility and easier installation

nnnn

■ Variety of elastomer and fabric combinations meet the

nnnn

demands of temperature, pressure and media

nnnn

Design

nnnn

■ Tube

nnnn

• Chlorobutyl resists cracking due to high tempera-

nnnn

tures, weathering, oxidation and chemicals

nnnn

• Abrupt arch configuration provides maximum

nnnn

movement, and pressure and vacuum resistance

nnnn

• Seamless tube creates a positive flange seal

nnnn

without gaskets
