Forming the Roll Groove
Pipe wall thickness cannot exceed the maximum wall thickness specified in the "Pipe Maximum and
Minimum Wall Thickness" Table. Do not use to groove 8" schedule 40 steel pipe harder than 150 BHN.
Pipe size
2 1/2"
3"
3 1/2"
All dimensions are in inches.
NOTE! Groove diameter should be measured using a Diameter - tape.
Periodically check groove with a Diameter-Tape or similar measuring device.
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.
