Water-Blasting / Hydro-Blasting

Water-Blasting or Hydro-blasting can clean some of the toughest materials in your facility. We understand the advantages of this technology and we continually invest in the newest state of- the-art equipment .We also performs our research and development and fabrication of specialized automated and robotic cleaning equipment designed specifically for our customer needs. Mg service s Water-Blasting / hydro- blasting fleets and seasoned field technicians effectively remove the toughest deposits from boilers, tanks, exchangers, condensers, vessels, pipelines and any other surfaces requiring superior water-blasting results up to 40K P.S.I. Also utilizing up to 700hp "Big Water" pumps which produce high volumes of water at low pressure to flush Air pre-heater fly ash, or lance plugged drain lines efficiently. The sheer power of these units allows several rotary nozzles to run at once while cleaning utility boilers. They can also power multiple handguns or lances when cleaning large condensers or evaporators.

Abrasive Blasting

MG Services has improved the use of soft abrasives for cleaning industrial process equipment. In some cases, abrasive blast cleaning is superior to hydroblasting or chemical cleaning. Our abrasive blasting services can be used on surfaces to remove coatings, soils, or discolorations. This is now an accepted service for IRIS and other NDT inspections. Abrasive blasting services can be used on floor coatings, industrial structures, tank linings, process units and equipment, piping and containment structures.

One of the benefits to using abrasive cleaning is that it is environmentally friendly (non hazardous and biodegradable). It is safe to use around rotating equipment and worker safety is enhanced due to low pressures. The end result is cleaner tubes for IRIS and other NDT inspections.

• Exchanger tube cleaning for IRIS and other NDT inspections
• Fin-Fan cleaning for IRIS and other NDT inspections
• Cosmetic cleaning
• Dry abrasive tube cleaning (ID and OD)
• Slurry blast tube cleaning (high pressure water and abrasives)
• Surface preparation, with the use of soluble and non-soluble abrasives
• Expert matching of blast media to metallurgy

What is Abrasive Blasting?

Abrasive blasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants. A pressurized fluid, typically air, or a centrifugal wheel is used to propel the blasting material (often called the media). The first abrasive blasting process was patented by Benjamin Chew Tilghman on 18 October 1870. There are several variants of the process, such as bead blasting, sandblasting, sodablasting, and shot blasting.  

Media

In the early 1900’s, it was assumed that sharp-edged grains provided the best performance, but this was later demonstrated not to be correct.

Mineral: Silica sand can be used as a type of mineral abrasive. It tends to break up quickly, creating large quantities of dust, exposing the operator to the potential development of silicosis, a debilitating lung disease. To counter this hazard, silica sand for blasting is often coated with resins to control the dust. Using silica as an abrasive is not allowed in Germany, United Kingdom, Sweden, or Belgium for this reason.

Another common mineral abrasive is garnet. Garnet is more expensive than silica sand, but if used correctly, will offer equivalent production rates while producing less dust and no safety hazards from ingesting the dust. Magnesium sulfate, or kieserite, is often used as an alternative to baking soda.

Agricultural: Typically, crushed nut shells or fruit kernels. These soft abrasives are used to avoid damaging the underlying material such when cleaning brick or stone, removing graffiti, or the removal of coatings from printed circuit boards being repaired.

Synthetic: This category includes corn starch, wheat starch, sodium bicarbonate, and dry ice. These “soft” abrasives are also used to avoid damaging the underlying material such when cleaning brick or stone, removing graffiti, or the removal of coatings from printed circuit boards being repaired. Sodablasting uses baking soda (sodium bicarbonate) which is extremely friable, the micro fragmentation on impact exploding away surface materials without damage to the substrate. Additional synthetic abrasives include process byproducts (e.g., copper slag, nickel slag, and coal slag), engineered abrasives (e.g., aluminum oxide, silicon carbide or carborundum, glass beads, ceramic shot/grit), and recycled products (e.g., plastic abrasive, glass grit).

Metallic: Steel shot, steel grit, stainless steel shot, cut wire, copper shot, aluminum shot, zinc shot. Many coarser media used in sandblasting often result in energy being given off as sparks or light on impact. The colors and size of the spark or glow varies significantly, with heavy bright orange sparks from steel shot blasting, to a faint blue glow (often invisible in sunlight or brightly lit work areas) from garnet abrasive.
