What type of green silicon carbide is used for corrosion protection of pipeline interiors?
Green silicon carbide grades with different particle sizes are available for pipeline interior corrosion protection. The specific selection depends on the construction process and protection requirements. The following are common grades and their applications for reference:
Micronized Powder Grades:
F280/F320/F400 (particle size 40-63μm): Suitable for sandblasting pretreatment, removing the oxide layer on the pipeline interior and roughening the surface to improve coating adhesion.
F600/F800/F1000 (particle size 10-40μm): Used in the preparation of anti-corrosion coatings or wear-resistant coatings, providing a fine filling effect and enhancing coating density.
F120 0/F1500/F2000 (particle size 5-20μm): Suitable for high-precision corrosion protection applications, such as precision pipes or surface treatments requiring a high finish.
Grit sizes:
24#-60# (particle size 0.85-1.5mm): Suitable for rough grinding of pipe interiors, removing burrs and old coatings.
Recommended selections:
To improve coating adhesion, choose F280-F400 micropowders.
For wear-resistant coatings, choose F600-F1000 micropowders.
For roughening, choose 24#-60# grit.
