The PBT-2 is an accessory for all Contracor blast
machines that allows easy cleaning of the internal
surface of steel pipes. It is durable, portable, and most
of all, easy to use, allowing considerable increases in
productivity.
The PBT-2 consists of an adjustable centre carriage
on which a pneumatically driven motor is mounted,
which rotates the blast head to produce a uniform
cleaned blast surface.
The carriage is infinitely adjustable from 12” (300mm)
to 36” (900mm) inside diameter.
The motor is driven by compressed air. The rotational
speed is infinitely variable, allowing high operational
flexibility with all degrees of corrosion of the inner
surfaces.
The PBT-2 unit can be operated with nozzle sizes from
5.0mm to 9.5mm inner diameter.
