Roll Grooving Tips
1. If pipe tends to “walk off” drive roll, increase offset dimension.
2. If drive roll flange shaves pipe end, decrease offset dimension.
3. If pipe end flare is excessive, lower pipe end to level with roll groover.
4. If pipe wobbles and/or “walks off” the drive roll, raise pipe end to level with roll groover.
5. Short lengths of pipe (under three feet) may require slight pressure to maintain the degree offset
dimension.
