I need to put in 580 meters of 63mm PN10 PVC for the final section of a 12km distribution line. We don't have any 63mm in stock so can I just use two 50mm pipes in parallel? The internal area of the 63mm pipe is about 22cm2 and the internal area of the 50mm pipe is about 12.5cm2 so two 50mm pipes should be about the same. Is my logic correct?
