This hydraulic roll groover equips with updated hydraulic pump,
with convenient depth adjusting function, powered by 750w induction
motor, is capable of grooving 1''-6'' pipes. Separate knurling
roller design of drive shaft for convenient replacement.
● This machine is designed for grooving 8-24" steel pipe, its
specified tool for the connection of heavy duty couplings and
grooved pipes.
● Equipped with new hydraulic pump and stroke limitation devices to
make the depth of grooves more precisely and effectively
● Powered by high-performance gear reducing motor, equipped with
the guide wheel unit ensures high quality grooves and high working
efficiency.
● Equipped with a foldable hydraulic steel pipe stand to make
operation convenience and save labor.

OPERATION OF ROLL PIPE GROOVING MACHINE
Choose the right pinch roller and knurl wheel and install them onto
the roll grooving machine.
Put the pipe on the knurl wheel and pipe stands. The pipe stands
should be placed at the position of 3/4 length of pipe. Then adjust
the pipe stands height to make sure the pipe are 1 degree lower than the
horizantal level.
Tighten the relief valve, shake the hydraulic pump handle, let the
pinch roller going downward until it touch the surface of pipe end.
Rotate the limit nut down, make it contact with the oil pump top frame.
Check the correct data of groove depth for different diameter pipes
in the chart. For instance, if we roll groove on a 8 inch pipe, the depth
will be 2.34mm. Calculate from the red start line, rotate the limit
nut 2.34mm up, then turn the fastening nut down until it touch the limit nut
and fix it. (One circle rotation on the limit nut is equal to
2.5mm) Rotate the
side guide wheel to support the pipe. Release the relief valve.
Connect the power plug, turn on the switch to run the machine.
Tighten the relief valve again and pump the handle to start
grooving. Continue to swing the handle until the limit nut reach the oil pump top
(Please do not swing too fast). Allow the pipe to rotate additional
one or two turns to make sure the groove is completed. At last turn off the switch
and release the relief valve knob. Rotate the guide wheel to make
it away from the pipe. Remove the pipe and check the groove depth with a pipe
groove measuring tape.
