What is hydro blasting ?
Hydro blasting is the use of high speed streams of high pressure water with different flow rate to cut through almost all solid materials and to clean various surfaces.
Hydro blasting can be just pure water or water with sand to clean chemicals or other additives at an operating pressure of between 10,000 to 25,000 psi (70 to 170 MPa) from a system . That includes an engine, pump, water storage tank hose, specialized nozzle and other accessories. The terms “pure water jetting” and “abrasive jetting” are also used.
Manual hydro blasting can be hazardous to untrained or unskilled users.
Hydro blasting has been used since the 1950s and more features have been added to the basic components. Some hydro jetting machines are now computerized. In many industries, it is replacing or used along with other machining and cleaning methods or procedures. It offers many advantages in terms of performance capability, flexibility, safety and operational costs as briefly discussed .
Coating removal and surface preparation
Many current models of high pressure water blasting equipment have better process controls and more efficient nozzles that meet the needs of various users as well as the standards established by the Atex.
High pressure hydro blasting also operates with fewer environmental and health issues. And does not damage the substrate surface profile like “overblasting” compared to abrasive blasting.
Hydrodemolition
Ultra high pressure water blasting has provided construction engineers and contractors with the effective, fast, less costly, much more precise and quiet alternative to jackhammers, to cut and remove concrete, stone and similar hard surfaces.
Hydro blasting is forced to pass through the small hole or orifice of the jet nozzle. Where the restriction of the small orifice results in a high pressure water stream.
Sewage system preventive maintenance
Hydro blasting machine is the complete solution to pipe clogging problems because after breaking up clogs. It also thoroughly cleans the pipe walls.
Machining
Like laser cutting, high pressure water cutting can be set to cut intricate shapes without tools. it is sometimes called a “water cutter.” One advantage it has over laser cutting is that any heat produced is absorbed by water. Which makes it capable of cutting some plastics, stone, brass, bronze and composite material which lasers can’t cut because the heat generated will produce toxic fumes and dust, or deform the edges.
