The MINI-TUBOBLAST has been designed for the internal blasting of little pipes. It's equipped with a venturi nozzle combined with a end's in tungsten carbide, which conveys the abrasive with a 360° conical jet on the pipe to be blasted.
The little pipes, until 20 mm, could be blasted using some centring collars.
MINI-TUBOBLAST is feeded by our sandblasting machines and is equipped also by a stainsteel bar length 6 x 3/8", which is used for abrasive passage but also for the advance of the Mini-Tuboblast inside the pipe.
It's complete with fittings for the connection to the sandblasting machine.
