It is a very common misconception that ABS and PVC pipes are "glued" together. The process that joins them is very similar to welding steel. The process is done chemically and is called solvent welding. The so-called glue is actually a solvent that briefly melts the top surfaces of the pipe and fitting and allows the two surfaces to combine when the joint is assembled. Then the surfaces harden and the joint is complete. While ABS and PVC are different chemically and require their own solvents, the process is essentially the same. Your joints will be fine. The main thing is when assembling the pipes, don't move a joint for a minute or so after assembly so that the solvents can set without cracking.
