What is ultra high pressure water jetting?
Ultra high-pressure water jetting, or UHP water jetting, is simply the practice of using highly pressurized water to remove a coating or contaminant from a substrate. Sometimes this is achieved by blasting glass, grit or another abrasive material at high pressures onto a surface.
What pressure is Hydroblasting?
5,000 to 30,000 psi
There are two levels of high pressure washing, based on the water pressure used: High pressure waterblasting–5,000 to 30,000 psi. Ultra high pressure jetting – greater than 30,000 psi.
What is SSPC SP12?
SSPC-SP12 / NACE 5 Surface Preparation and Cleaning of Steel and Other Hard. Materials by High- and Ultra High- Pressure Water Jetting Prior to Recoating. This standard requires water jetting at high- or ultra high-pressure to prepare a surface for recoating using pressure above 10,000 psi.
What is UHP water blasting?
When you blast with ultra-high pressure water jetting you can increase your performance by using a rotating lance gun that gives you a wider blasting pattern, because they have multi-orifice heads. UHP rotating lances use an air-driven motor that drives the nozzle assemblage.
What is considered high pressure water?
Your home’s water pressure typically ranges between 40 and 80 psi (pounds per square inch). Water pressure below 40 psi is considered low, and water pressure above 80 psi is considered too high. Having the water pressure set too high, over 80 psi, can lead to broken water pipes and costly bills.
What is Hydroblast?
Hydroblasting is a technique for cleaning surfaces, which relies entirely on the energy of water striking a surface to achieve its cleaning effect. Abrasives are NOT used in hydroblasting systems. Consequently the problems caused by dust pollution and by the disposal of spent abrasives are eliminated.
Is Hydroblasting the same as pressure washing?
If you need a more heavy-duty industrial cleaning solution, you need a water blaster. As well as cleaning and lifting dirt like pressure washing, water blasting also removes a thin layer of the surface being sprayed.
What does Hydroblasting mean?
What is SSPC SP2?
SSPC-SP2- Hand Tool Cleaning Hand tool cleaning refers to surface preparation that uses non-power handheld tools to clean a steel surface. Hand tool cleaning is intended to remove all loose mill scale, rust, paint and other contaminants that may be detrimental to a coating application.
What is SSPC sp16?
SSPC-SP 16, Brush-Off Blast Cleaning of Coated and Uncoated Galvanized Steel, Stainless Steels, and Non-Ferrous Metals, is a surface preparation standard from the Society for Protective Coatings covering preparation of galvanized steel prior to the application of paint or powder coat.
What is soda blasting?
Soda blasting is a method of removing surface contaminants and coatings by using sodium bicarbonate (baking soda). Compressed air from specialized blasting machines propel particles against the surface to be cleaned.
Is the standard applicable to all surfaces produced by hydroblasting?
The standard however is applicable to surfaces produced by a whole range of hydroblasting pressures, providing the equipment used is capable of cleaning to the visual standard depicted. The steel surfaces produced by hydroblasting do NOT look the same as those
What is the difference between high pressure and ultra high pressure hydroblasting?
•High pressure hydroblasting, operating at pressures between 10,000 and 25,000 p.s.i. (70-170 Mpa). •Ultra high pressure hydroblasting, operating at pressures above 25,000 p.s.i. (170 Mpa) and typically between 30,000 and 36,000 p.s.i. (207-250 Mpa) – See note 5.1. This visual standard has been prepared by the use of ultra high pressure
How can I make sure the job is blasting to standard?
required standard by blasting a small test area prior to the main blast may help, providing the rest of the job is blasted to the same standard. Methods for ensuring the rest of the job is blasted to the same standard will vary from project to project.
What is the maximum pressure of hydroblasting?
pressures are commonly encountered. •High pressure hydroblasting, operating at pressures between 10,000 and 25,000 p.s.i. (70-170 Mpa). •Ultra high pressure hydroblasting, operating at pressures above 25,000 p.s.i. (170 Mpa)
