Product Introduction
Product Overview
Titanium storage tanks are the most durable and corrosion-resistant solution for storing sodium hypochlorite (NaOCl). Due to titanium's excellent resistance to strong oxidizing chemicals, the service life of titanium tanks can reach 30 years or longer, significantly reducing long-term maintenance and replacement costs.
Commercially pure Grade 2 titanium is the most commonly used material for NaOCl storage applications.

Product Advantages
Excellent Corrosion Resistance
Titanium provides outstanding resistance to:
Sodium hypochlorite
Seawater
Aqua regia
Chlorine-based oxidizing media
Titanium naturally forms a protective oxide passivation layer that prevents further corrosion.
Lightweight & High Strength
Compared with steel tanks, titanium tanks provide:
Lower structural weight
Higher mechanical durability
Better safety performance
Low Long-Term Operating Cost
Although the initial purchase cost is higher, titanium tanks provide:
Extremely low maintenance costs
Long service life
Reduced downtime risk
Sodium Hypochlorite Storage Requirements
Sodium hypochlorite is a strong oxidizing solution used for disinfection and industrial cleaning. Proper storage is critical because NaOCl can decompose and release oxygen gas under poor storage conditions.
Key Storage Considerations
1. UV Protection
Ultraviolet radiation accelerates NaOCl decomposition.
Storage tanks should minimize light exposure.
2. Metal Ion Contamination Control
NaOCl is highly sensitive to transition metal contamination.
Compatible metals include:
Titanium
Platinum
Gold
Silver
Tantalum
Metals that should be avoided:
Stainless steel
Copper
Brass
Hastelloy
Monel
Copper contamination is particularly harmful because Cu²⁺ ions accelerate NaOCl decomposition and increase oxygen gas production.
3. Corrosion Resistance Requirements
The storage tank material must resist oxidation and chemical attack to maintain solution stability.
Material Comparison of Storage Tanks
| Storage Material | Estimated Service Life | Purchase Cost | Maintenance Cost | Notes |
|---|---|---|---|---|
| HDPE / XLPE Tanks | 4 – 7 years | Low | Low | Economical but shorter lifespan |
| Rubber-Lined Steel Tanks | 3 – 6 years (lining) | Medium | Medium | Lining requires periodic replacement |
| Fiberglass Tanks | 10 – 15 years | Medium | Medium | Requires corrosion barrier maintenance |
| Titanium Tanks | 30+ years | High | Very Low | Best long-term performance |
