Benefits of Grit Blasting in Canada
Grit blasting offers numerous advantages that enhance the operational efficiency and longevity of heat exchangers. One significant benefit is the improvement of heat transfer efficiency by blasting away accumulated fouling. By creating a clean surface, grit blasting reduces fouling thermal resistance, which is crucial in applications like heat exchangers.
In addition to enhancing heat transfer, grit blasting significantly improves the surface finish, making it less susceptible to fouling, which in turn makes it more resistant to corrosion via fouling mechanisms. This protective measure extends the lifespan of components, reducing the need for frequent replacements. Furthermore, grit blasting prepares surfaces for coatings or linings, ensuring optimal adhesion and durability.

FAQs
What is the difference between grit blasting and sand blasting?
While often used interchangeably, "grit blasting" and "sandblasting" refer to the same process of surface cleaning and preparation using abrasive particles propelled at high speed, but "sandblasting" is a more general term that can include any abrasive material, while "grit blasting" specifically refers to using grit, like steel grit or recycled glass grit. The materials used in grit blasting are typically softer and more frangible than traditional sand, allowing for more safer metal surface integrity. Sandblasting with actual silica sand has become less common due to health concerns related to silica dust exposure (silicosis). Modern "sandblasting" operations now use a variety of safer media, including glass beads, plastic media, and walnut shells, depending on the application requirements.
Is grit blasting hot work?
Hot work includes welding, cutting, burning, abrasive blasting, and other heat-producing operations. Hot work presents an increased risk of fire and explosion hazards because it is most often performed in confined and enclosed spaces. Grit blasting is indeed classified as hot work in many safety protocols and regulations. The friction generated by high-velocity particles striking surfaces can create sparks and heat, potentially igniting flammable materials or atmospheres. This is particularly concerning in environments with combustible dust, vapors, or gases. For this reason, proper safety measures must be implemented when conducting grit blasting operations, including adequate ventilation, removal of flammable materials, fire watch personnel, and appropriate permits when working in regulated environments. Safety protocols should always be followed to minimize these inherent risks.
Is grit blasting dangerous?
Grit blasting carries several significant hazards when proper safety precautions aren't followed. The primary risks include respiratory dangers from airborne dust particles, which can cause silicosis and other lung diseases if appropriate respiratory protection isn't used. The high-pressure propulsion system creates noise levels that can cause hearing damage without proper ear protection. Additionally, the abrasive particles can cause serious eye injuries or skin abrasions when they ricochet off surfaces. Other hazards include confined space risks, potential fire hazards from sparks, and ergonomic issues from managing heavy equipment. With proper training, ventilation systems, personal protective equipment (including full-face respirators, hearing protection, and protective clothing), and adherence to safety protocols, these risks can be significantly reduced, allowing grit blasting to be performed safely.
