Water jetting

Water jetting (Water at ultra-high pressure)

For surface preparation and subsequent application of paints.


With the addition of the new automatic water jetting system (3000 bar pressure), surface preparation of large structures has changed.

It is the most sophisticated equipment in the world for maintenance of tanks, chimneys, ships, piping systems and pools.

It offers a technically efficient, fast, safe, economical and sustainable solution commanded manually or by remote control.

The most common uses of this technique are:

  • Surface-preparation of surfaces before painting.
  • Internal and external cleaning of heat exchangers and condensers.
  • Internal cleaning of pipes, tanks and containers.
Estimated performance 70 m2/Hour 8 m2/hour per nozzle.
Pollution None High. It causes lung cancer by 35% of involved and nearby workers. Disease known as silicosis.
Type of work Cold working Hot working in sand blasting as well as wet sand blasting.
Residues The only residue is the removed paint. It is contained in a vessel. About 0,2 kg/m2. It produces 40 kg/m2 of contaminated sand. The equivalent to the robot would produce 2,800 kg of contaminated sand per hour of work.
Dust Zero It must be removed to prevent the failure of the coating.
Invisible pollutants It eliminates 100% of invisible pollutants. It is necessary to perform a hydro cleaning before the blasting and another after it. This still fails to remove 100% of pollutants.
Warranties Paint manufacturers offer extended warranties when working with this method. Limited warranties. It is necessary to use the Bresle method to ensure proper cleaning.
Interference It does not interfere with other works. Other works can be performed simultaneously with the treatment. No tasks can be performed nearby.
Times Being automatic, this is a constant process that reduces project times by more than 60%. It depends on the weather and the mood of the workers.
Lead paint It can be removed without coming into contact with staff. It is impossible to remove without generating dust in surface and affecting the health of the workers.
Elastomeric paint/fiberglass Easily removed. It is very slow and it is often necessary to use a mace before blasting to remove it manually.
Security Being a robot the one that executes the work, it is a highly secure task. It is a highly risky task. Staff in height with pollution present, assisted air masks and hoses under pressure in their hands ...
Technology Last generation. Used and recommended by the most advanced oil companies and the most important navies of the world, from the US to the Brazilian, Chilean, Uruguayan and Argentinean navies. Both outdated and prohibited in all developed countries as well as in Brazil, Chile and Uruguay as it is considered extremely harmful to health.
