Ultra-High-Pressure (UHP) water blasting
Plastocor Introduces PLC controlled Ultra High Pressure water blasting equipment for increased efficiency in surface preparation.
In order to safely remove coatings and other durable linings such as rubber, Plastocor, Inc. has relied on Ultra High Pressure (UHP) water blasting. When used properly UHP will clean and decontaminate without damaging a metal substrate. The vital elements of UHP are:
– 30,000 to 40,000 psi: ultra high pressure to perform the work
– 4 to 5 gpm: low flow to keep the “kick back” of the gun manageable
– Very small orifice size: provides high pressure at low flow
– Multiple orifices on one gun head: provides greater working area
– Gun head rotates: provides sweeping motion of the multiple jets to maximize efficiency and
The keys to success when using UHP are:
– Experienced and skilled technicians who work SAFELY and efficiently
– Having proper and reliable equipment and protective gear
While Plastocor, Inc. has always performed the UHP work with our skilled technicians, we have traditionally relied on sub-contractors to provide the equipment. This equipment has consisted of diesel driven pumps that get a lot of run-time. These pumps must be located outside often necessitating long hose-runs and wall penetrations. Additionally, the diesel engines needs to be maintained, permitted, and the fuel carefully controlled.
Pumps driven by electric motors avoid these issues. They can be quickly setup inside, near the work area, without emission or fuel issues. Modern electric motors are PLC controlled which allows for precise pressure control with minimal starting amp requirements. And reliability is rock solid.
For these reasons, Plastocor, Inc. has acquired a dedicated fleet of electric pumps. The combination of our highly skilled UHP technicians and these low-hour/high efficiency electric pumps makes for an enhanced level of service.
Plastocor, Inc. welcomes the opportunity to address your UHP needs.
