CONTRACOR

PBT-2 Internal pipe blasting tool

1.2 General description

PBT-2 ROTOBLAST is a high-performance mobile device for abrasive blast cleaning of the

inner surfaces of pipes, and is powered by a standard abrasive blast machine.

1.3 Technical characteristics

PBT-2 ROTOBLAST is suited for operating in straight pipes up to 12m in length and with

diameters from 360 to 900 mm.

In order to operate the PBT-2 ROTOBLAST, CONTRACOR NTC(F)-series abrasive blast

nozzles with 6.5 – 9.5 mm diameter are required.

PBT-2 ROTOBLAST connects to the abrasive blast machine in place of a standard abrasive

blast nozzle.

The device requires compressed air with 7–8 bar pressure and the displacement volume

given in the table below. The abrasive-air mixture must be fed along a hose with a mini-

mum diameter of 1 ¼”. Using hoses with a smaller diameter will lead to quick wear and

reduced cleaning performance.
