Ultra-high pressure, as defined by the National Association of Corrosion Engineers (NACE) is water pressures over 30,000 psi. UHP Water Jetting removes coatings, rust, and other tough adherents without the hazards of abrasive blasting. The resulting surface meets or exceeds all recognised standards (including the WJ-1 or “white metal” specification of NACE No. 5/ SSPC-SP 12).
Water Jetting is also the only way to meet the SC-2 standard for removing soluble salts, which hamper adhesion and often lead to coating failure.
During abrasive blasting, these contaminants are often trapped in cavities within the metal. UHP water jetting cleans deeply enough to prevent these invisible “corrosion cells” from forming, and restores the surface’s original profile.
The benefits of Ultra High Pressure Water Jetting:
Surface preparation - Removal of coatings - Concrete demolition - Automated flex lance tube cleaning - Tank & vessel cleaning - Pipe de-scaling & cleaning - Line marking removal - Drain cleaning - CCTV pipeline inspection - Underwater inspections
Construction - Shipping - Defence - Agriculture - Mining
