The collaring range of TEC-150-8 machine is even up to 8'' on run pipes 1’’ – 20’’ IPS. The machine makes the elliptical pilot hole, forms a collar from the run pipe and trims the collar up to 6''. Pilot holes larger than for 6'' collar are burned manually, e.g. with plasma cutter before placing the pipe to the machine.

Larger trimming unit, jib arm and the positioning device for centering of the pilot hole/ run tube to the machine.
The standard machine cannot be retrofitted to 8'' capability.
