What is UHP Waterjetting? Description of UHP Technology Method of Cleaning Surface Appearance after Cleaning Advantages of this Cleaning Method Conclusions

Description of UHP Technology Ultra High Pressure surface preparation uses of waterjets at pressures up to 40,000 PSI and flow rates of up to 10 GPM to remove coatings, hard deposits and rust scale which are tightly adhered to the base metal. The high velocity waterjets strike the surface to be cleaned in much the same manner as small solid particles, shearing away unwanted materials from the surface. Our high pressure pumps and variety of rotating tools give great flexibility in the types of applications for which ultra high pressure water can be used. This equipment has been greatly improved in the last 5 years and is now an economically feasible alternative in many cleaning applications. UHP Projects, Inc. uses an internally compensated, positive displacement pump capable of 40,000 PSI discharge pressure. Because it is a direct drive mechanical pump, its efficiency is above 90%. The internal pressure compensation allows us to run multiple surface preparation tools from one pumping unit with no loss in effectiveness. These advantages allow us to get higher productivity with less equipment on the job site. UHP Projects, Inc. also makes several modifications to the units to increase maintenance intervals and decrease downtime. As with all high pressure pumping systems, this equipment requires proper maintenance and care. It is highly dependent on proper operator training to keep downtime to a minimum. Due to the precise nature of replacement parts, the operating costs are also very dependent on operator training. UHP Projects, Inc. takes great pride in the level of expertise found in our supervisory staff. This training cannot be taught in a classroom, it can only be gained by proper training in the field, augmented by an organized training program. Our onsite Project Managers are the reason for our excellent reputation. Because they are well versed in both UHP waterjetting and recoating procedures they are able to ensure quality work. All of our Project Managers are familiar with equipment maintenance, which allows quicker repairs and less maintenance downtime.
