Pipe Rounding Instructions
No ductile iron pipe is a perfect circle, especially after cutting. It is a cast product, not machined, and no matter whom the manufacturer is, slight ovality is a reliable given. Once cut, any pipe has the potential to be “out of round”. This is not in any way an indication of “bad” pipe, just one that has been annealed (heat-treated). These pipe rounding instructions take “out-of-round” out of your construction vocabulary. The instructions are intended and designed to fix this after cutting. With them you can easily change the shape of the pipe, from the outside, during joint assembly.
