Hydro-torque Cutter Can Rehabilitate Problem Pipes

Pipes blocked by tuberculation, mineral deposits or concrete often are prime candidates for replacement. Paikert/Intruder hydro-torque cutters from NozzTeq® Inc. provide an alternative.

“This next-generation series of pipe cutters gives customers the option to reinstate pipes without costly excavation,” says Scott Paquet, president and CEO. Powered by water pressure from a standard jetter, the cutter’s impact drill motor runs at low speed, but provides high torque. The constant water pressure ensures the drilling head does not stop when it meets obstacles. Low-pressure vents direct spent water out the front, lubricating and cooling the cutting wheels, and out the sides and rear, removing debris.

The cutter can be used in three operating modes. “In the impact-and-drill operating mode, the cutting head pulverizes blockages,” Paquet says. “In the impact-only mode, you can use it as a ramming tool. The drill-only mode is for more precise, clean cutting.”

At 60 to 65 gpm, the unit delivers about 1,000 blows per minute at 200 rpm.

It is available in three different models: The SB-82 for 4- to 6-inch pipes (requires a minimum of 40 gpm); the SB-110 for 6- to 26-inch pipes (minimum 60 gpm); and the SB-150 for 27- to 36-inch pipes (minimum 90 gpm). Each model can be adapted to fit on various sizes of sleds.

“The cutter requires no lubrication after usage,” Paquet says. “You can use it continuously for a week or so without doing anything to it. That saves maintenance time and provides an advantage on jobs where you don’t want oil left in the pipes.”

A redesigned valve system eliminates valve adjustments. “Before, the valves had to be adjusted according to the jetter’s flow rate, which could take anywhere from one to three hours,” Paquet says. Other parts were re-engineered for greater durability. Each drill head can accommodate a variety of standard or custom-built cutting accessories.
