UHP blasting machines from in-dock cherrypicker type systems to magnetic and suction climber robots under scrutiny.
Hydroblasting is a technique for cleaning surfaces that relies entirely on the energy of water striking a surface to achieve its cleaning effect. Abrasives are not used in hydroblasting systems, which eliminates the problems caused by dust pollution and the disposal of spent abrasives associated with grit blasting. Two different hydroblasting operating pressures are commonly encountered.
High pressure hydroblasting which sees operating pressures of between 10000 and 250000 psi (70-170MPa) and ; Ultra high pressure hydro blasting which sees operating pressures above 250000 psi (170MPa) and typically between 30000 and 360000 psi (207-250 MPa).
There also a number of systems on the market that are able to deliver UHP hydroblasting, including an increasing number of remote controlled or robotic systems. These range from in-dock cherrypicker type systems, such as those produced by Hammelmann, to magnetic and suction climber robots. |
