Applications
- High-Temperature Corrosion Protection: Protects equipment and pipelines in high-acid and high-sulfur atmospheric and vacuum distillation units, particularly in the oil phase. Not recommended for high-temperature water-phase applications.
- Phosphorus-Free Corrosion Inhibitor Formulations: Used as a base for formulating phosphorus-free corrosion inhibitors, diluted with diesel, aromatics, or similar solvents.
Usage Instructions
1. **Dilution:** Dilute the product with aromatics, diesel, or other organic solvents. Recommended dilution concentration is 20-35%.
2. **Winter Use:** Heat the product to improve fluidity before dilution if stored in low-temperature conditions.
