• Sand Blasting Surface Treatment SA2.5
1. Comprehensive sandblasting on both the interior and exterior of the valve body for a pristine finish and optimal surface preparation.
2. Achieve a refined surface post-sandblasting, ensuring robust paint adhesion for enduring performance.
3. Should the oxygen content within the medium exceed 23.5%, opt for external sandblasting only, as internal sandblasting becomes unnecessary.•
