Application of white corundum 60# in sandblasting of petroleum machinery?
White corundum 60# is very suitable for sandblasting in the field of petroleum machinery due to its high hardness, cleanliness and good roughness, especially in high-demand occasions:
Typical application objects:
Oil drilling equipment: drill pipe, drill collar, casing, tubing, wellhead equipment, blowout preventer, etc. At the oil field site, these equipment often face mud and salt water corrosion, and the surface needs to be thoroughly cleaned.
Refining equipment: pressure vessels (such as reactors, towers, storage tanks), heat exchangers, pipelines, valves, etc. The inner walls of these equipment often need to be treated to remove coking or old coatings.
Offshore platform equipment: various steel structures, pipelines, decks, etc., are exposed to harsh marine environments for a long time.
Main purpose:
Surface cleaning: Thoroughly remove rust, scale, welding slag, oil stains, old coatings, etc. on the surface.
Surface roughening: Form a uniform, clean, anchor structure with appropriate roughness, providing an excellent anti-corrosion foundation for subsequent high-performance anti-corrosion coatings (such as epoxy, polyurethane, glass flake mastic, etc.). This is the core of long-term anti-corrosion for oil equipment.
Eliminate slack: Sandblasting also helps to eliminate some surface slack.
Beautify the appearance: Get a consistent and consistent metal appearance.
