One of the major growth areas in water jet utilisation is the removal of paint, coatings, and corrosion as a surface preparation method prior to recoating, commonly referred to as Hydroblasting.

The method has several advantages over abrasive blasting; i.e. no abrasives are used, eliminating dust, grit contamination and damage to surrounding equipment such as pumps, compressors, instrumentation etc.

Other trades can work in the vicinity without exposure to health risks associated with dust inhalation.

No grit clean up or disposal costs and the ability to selectively remove coatings and improved feathering of edges for spot blasting.

Hydroblasting can be carried out on equipment in service such as storage tanks, pipelines, production plant, vessels at sea etc, so the costs involved in completing tight work schedules during plant shutdown or vessel docking can be dramatically reduced.

Hydroblasting is environmentally friendly, and most importantly, dramatically reduces levels of chloride contamination on the prepared surface, limiting the potential for future corrosion. Hydroblasting removes the electrolytes that cause corrosion, leaving a cleaner surface, resulting in longer coating life.

When used to remove materials that are resistant to abrasive blasting, such as fiberglass, rubber linings, glassflake paints, and fireproofing coatings, hydroblasting can be up to twenty times faster

If you would like to know more about hydroblasting, we will be happy to give a technical presentation at your facility.
