NLB waterjetting is a highly productive, economical surface preparation method that produces a "white metal" finish - up to the WJ-1 (International Standard).
The process leaves a surface contaminant-free and exposes the underlying blasting profile 100%. There is no risk of bent peaks, which traps corrosion causing contaminants (soluble salts), dust contamination or grit embedment. All these defects are commonly associated with the incorrect application of abrasive blasting.
Water jetting is “spark-free”, making the surface preparation process intrinsically safe, which is of paramount importance in maintenance for the oil and gas industry. Furthermore water jetting is a dust-free process which makes it an ideal surface preparation method in locations where dust generation can cause damage to nearby machinery or equipment.
