• Sand Blasting Surface Treatment SA2.5
1. To ensure impeccable quality, we sandblast both the interior and exterior of the valve body, achieving an unparalleled smoothness.
2. Post-sandblasting, the surface is incredibly fine, ensuring exceptional paint adhesion that enhances durability.
3. If the oxygen content in the medium exceeds 23.5%, we conduct external sandblasting only, as internal sandblasting becomes unnecessary.•
