Aquablast and Jet Edge have specialised in Ultra High Pressure (UHP)
water jetting technology for 20 years.
Aquablast introduced Jet Edge's stunning 3,800 bar (55,000 psi) UHP water surface preparation system into their
product range five years ago and became the exclusive sales, service and technical service centre for Jet Edge
field operations in Europe and the Middle East.
55,000 psi UHP water jets work at three times the speed of sound!
Jet Edge guns flow at only eight litres per minute but the work rate is
much higher than any other UHP tool. The reaction force from eight litres
is extremely low and this makes Jet Edge UHP the most powerful but least reactive
and safest water blast tool available anywhere.
From their headquarters in Norfolk, United Kingdom and Minneapolis, Minnesota, USA, and service
centres in the Mediterranean and Arabian Gulf, the two companies offer solutions and support
for surface preparation and material separation requirements throughout the world.
Jet Edge and Aquablast are collaborating on new product development and innovative cleaning and cutting solutions
in the marine, petro-chemical, aerospace, food processing, nuclear and industrial waste re-cycling industries.
Jet Edge 55,000 psi UHP water demonstrates outstanding productivity
Comparison tests between surface preparation production rates at 55,000 psi (3,800 bar)
and 40,000 psi (2,750 bar) continue to show impressive results for using higher pressures.
Tests were recently done during a coating removal project on a water storage tank in
Essington, PA and specified removal of a top coat and lead based primer using waterjet
equipment. Comparison tests using both hand held guns and a robotic crawler showed
significant benefits to using the 55,000 psi over 40,000 psi.
Tests using the hand held Jet Edge GyraJet rotating gun showed over 100% increase
in speed when removing coatings at 55,000 psi. Results using 55,000 psi and the
robotic crawler showed more than 100% increase over 40,000 psi.
Comparisons were
also done using 2 different flow rates (12 gpm & 6 gpm / 45 lpm & 23 lpm) at 40,000
psi and surprisingly the 55k @ 4.3 gpm (16 lpm) even outperformed the 40k @ 12 gpm. (45 lpm).
Water blast productivity at 55,000 psi of almost 16 m2 per hour was nearly double that of
40,000 psi using exactly the same pump and application tools.
The coating comprised a lead-based primer and three vinyl topcoats totalling about 425
microns in DFT.
