Acclaimed for its speed and versatility, ultrahigh-pressure (UHP) waterjetting technology is quickly becoming the surface preparation industry’s standard for coatings removal. Here are a few reasons why:
Lower Costs Than Grit Blasting
Because only pure water is used to remove coatings with ISP equipment, waterjetting costs less than grit blasting by eliminating the need for collection, containment, and disposal of abrasive. High productivity and no cleaning means you can focus purely on your job’s success.
Reduced Overall Project Time
Removal of coatings with water instead of grit allows for other work to be completed during waterjet operation. Steel, mechanical, and electrical work, or even painting, can be performed concurrently with waterjet surface preparation, which means projects are completed in less time.
Produces A Cleaner Surface
A cleaner surface means reapplied coatings will last longer. ISP equipment removes coatings and leaves a near white metal surface with the original profile intact. Also, corrosion products are removed deep into the pits and leave your surface with a much lower level of residual chlorides than when produced with abrasive blasting.
Simply stated, UHP waterjetting prepares a superior surface faster, and at less cost. The first 40,000 psi waterjetting pump was developed as a direct result of Flow’s dedication to innovate the newest waterjet technologies for surface preparation. Now ISP offers 55,000 PSI pumps, the highest operating pressure available.
Our enthusiasm to produce the best ultra high-pressure waterjetting equipment has continued to rapidly evolve as the surface preparation industry has continued to grow. Today, we offer a wide range of surface preparation equipment rental that will improve your productivity and profitability.
UHP Water Blasting compared to Grit Blasting
- Cleaner surface- water-soluble chlorides and other interference materials are removed which allow the new coating to last longer. When the coating lasts longer, it will need to be painted less, with less money spent.
- UHP has the ability to work alongside other trades. With water you do not have to shut down the work area because of the sand cloud. This allows the other trades to continue working which results in greater productivity on the job. Grit does not get into your bearings, ventilation, and other mechanical equipment by way of grit blasting.
- Reduced clean up and associated labor. No longer do you have to spend days cleaning up the dry dock or work area. Another significant labor reduction.
- Increasing environmental scrutiny. Regulations regarding open grit blasting have become stricter. As public housing continues to encroach on shipyards & refiners the complaints and concerns will continue to increase.
- Grit disposal costs continue to rise and landfill options are becoming limited. Less waste reduces the need for complicated procedures.
- Increased water blast productivity. From water blast hand tools to the Deckhog & HydroCat the productivity jumps. The new increase now comes from the new generation 55K UHP unit. With the additional productivity, the race on who is faster really falls to water especially when you consider overall job costs.
- Industry acceptance. We are now at the point with UHP Water Blasting for surface prep that it is no longer an experiment or new technology. The industry has accepted the benefits, specifications are available and numerous coatings are made to be applied to water blasted surfaces.
- Tarps and JLG’s – Less are needed with UHP.
- Job footprint. Equipment location and footprint on a jobsite can be very critical.The overall job footprint is reduced compared to grit when you remove the Large Blast Pots, Large Compressors, Grit Bags, Storage Hoppers and other associated blasting equipment.
- During inclement weather, rain, UHP work can continue while grit blasting should be shut down.
