How to make a Pipe Cutter
The pipe cutter is used to remove excess cured lining that has overshot during the lining process into the main line. It may also be used to remove a partially collapsed liner where the lining has not bonded to the surface of the host pipe. In these cases, the Pipe Cutter can be used to cut the failed lining into short, 1m(3ft) sections and pulled out from the pipe. The pipe cutter can also be used to cut plastic pipes.
Select the correct Pipe Cutter for the Job. Choose your Pipe Cutter according to the soze of the original host pipe. Place the tool completely inside the pipe before powering up the tool.
PIPE CUTTER ULTRA FLEX
The pipe cutter can be attached to a Picote milling machine or for lengths less than 10m to a hand drill.
- The DN70 (3″) pipe cutter can be powered by the Micro, Mini, Midi, Mxi Miller or Super Midi.
- The DN100 (4″) & DN150 (6″) pipe cutters can be powered by the Midi or Maxi Miller Super Midi.
- The DN200 (8′) pipe cutter can only be used with the Maxi Miller or Super Midi.
- Wrap the panels evenly around the hub so that the blades point outwards. Put the entire pipe cutter inside the pipe.
2. Use a CCTV camera to measure the cutting spot. Push the pipe cutter into the correct spot. Use a low rotation speed when positioning the pipe cutter in the correct spot. When the tool is in the correct place, change the rotation speed to maximum. Use the CCTV camera monitor the cutting process. Do not let the tool move while cutting.
Step 3. After the successful cutting operation the cut piece of liner and pipe cutter will fall into the main. Change the rpm back to 500. Turn the power on and let the cutter turn around for a moment in the main before pulling it back inside the lateral pipe. Do not pull back the pipe cutter from the main unless the cutter is turning at low speed. If the cutter is not running a ta low rpm while pulling it back, the pipe cutter panels will spring open into the main. It will then be difficult to pull it back into the lateral. Running the pipe cutter at low rpm will help to collapse the panels back around the hub for easy removal.
