High / Ultra High Pressure Water Jetting
The ultra-surface preparation.
Ultra-High Pressure Water Jetting
Ultra-high-pressure water jetting is a method of surface preparation that uses water projected onto a surface at pressures between 25,000 and 36,000 psi. No abrasives are used in the operation as water jetting relies on the energy of the water striking the surface to achieve the preparation standard. This is used to remove protective coatings, scale, and rust. This is often used at sensitive sites such as petro-chemical where there is a greater risk of generating a spark.
An additional benefit of using UHP water jetting as a method of surface preparation is that any soluble salts and invisible surface contamination will be removed. Surface tolerant primers must be utilised after the UHP water jetting process to obtain the optimum adhesion strength between the primer and the steel surface.
High Pressure Water Jetting
Similar to ultra-high-pressure water jetting, however high-pressure jetting uses water pressures up to 10,000 psi. A dust free method of surface preparation, high-pressure jetting is used as a pre-treatment to remove surface contaminants such as salts, algae and more prior to application of the protective coating system.
With low water volume usage, this is an environmentally friendly surface preparation technique which has minimal effect on its surroundings.
