Victaulic 231S Non-Restrained Flexible Coupling
PRODUCT INFO
This style of coupling is typically used in exposed pipe applications for field joint connections whereaxial pipe movement due to thermal expansion or contraction of the pipe line is a factor.
Although Style 231S expansion couplings provide for a flexible joint and therefore do not prevent angular pipemovement, these couplings are not designed to accommodate static or dynamic angular deflection atthe joint.
Style 231S couplings should be used to accommodate axial pipe movement only. The Style 231S couplings can allow for up to 100 mm of axial pipe movement at the joint and therefore assist in avoiding the accumulation of thermal stresses due to changes in pipe length.
For these couplings to function properly, the pipe movement must be axially directed to the joint through the proper use of pipesupports, anchors and/or guides.
