6.4 Avoiding undue tension on joints
REHAU’s recommended best practice is to install a joint such that the pipe entering the fitting is straight and not on a bend.
When installing a joint on a bent pipe:
• The distance measured perpendicularly from the bottom of the outer edge of the sleeve to the outer edge of the bent pipe
must be at least 2.5 sleeve lengths (approx. 35mm for EDGE
TM
16 / approx. 38mm for EDGE
TM
20).
• As such, the maximum deflection of a branch pipe from the straight axis shall not exceed the following limits as shown in
