Pipework System Notes
This joint will not absorb pressure thrust forces. Being unrestrained, to function correctly it needs to be properly guided and the piping system must be provided with substantial main anchors to restrain pressure thrust forces imposed on the system.
RADCOFLEX recommends you consult your pipework engineer on pipework design and expansion joint selection.
