Is solvent welding capable of high strength?
Yes! Lap shear testing, as required by ASTM standards, determines the weld strength over time on flat samples of PVC plastic. Joint strength is +250 lbs/in^2 in two hours and slowly approaches the strength of the plastic in the pipe. The required end PVC strength is 900 PSI and the cure strength will often go much higher. In CPVC testing, under high temperature, the pipe walls often fail before the joints at an incredible 900 psi and 180F.
