James Walker Townson <strong>Rubber</strong> Comflex ® <strong>Expansion</strong><br />
Joint Type 56<br />
Type 56 is a hand-built cylindrical Comflex ® <strong>Expansion</strong> Joint. This<br />
process allows the overall length to be varied. It is only designed to<br />
compensate for lateral and angular movements. By its corrugated-free<br />
design an easy flow is possible with no sediment deposit.<br />
TYPE 56<br />
Design:<br />
Cylindrical bellows body with reinforcing inserts and built-in rubber<br />
profile for mating with swivel flanges. The expansion joint is<br />
self-sealing, additional gaskets are not required.<br />
Application:<br />
Noise and vibration damper, thermal expansion absorption in delivery<br />
pipe lines, on containers and pumps for media containing solid<br />
material.<br />

Flange:<br />
Swivel flanges (design A) both sides with integral sealing bead,<br />
no additional gaskets required (self-sealing). Flanges are drilled acc.<br />
to DIN PN 10 as standard. Other specifications according to<br />
DIN, ASA, BS and special flanges are also available.<br />
Flange Material:<br />
Standard S 235 JRG2 (RSt 37-2) zinc plated and yellow passivated.<br />
Other materials available on request.<br />
Note:<br />
Applicable only for lateral and angular movement (crease formation).<br />
Do not paint or insulate. See installation information.<br />
