Corrosion is the process by which a metal is gradually destroyed by chemical or electrochemical reaction with its environment. Corrosion can cause significant damage to metal structures and equipment, leading to costly repairs and replacements.
Hot dip galvanising is a process that coats steel with a layer of zinc to protect it from corrosion. The zinc coating acts as a barrier between the steel and the environment, preventing corrosive substances from reaching the steel surface.
The science of corrosion resistance in hot dip galvanised panel tanks
The corrosion resistance of hot dip galvanised panel tanks is based on two key scientific principles:
- Barrier protection: The zinc coating on hot dip galvanised panel tanks acts as a barrier between the steel and the environment, preventing corrosive substances from reaching the steel surface.
2. Sacrificial protection: If the zinc coating is damaged, the zinc will corrode preferentially to protect the underlying steel. This is because zinc is more anodic than steel, meaning that it will corrode first in an electrochemical cell.
Barrier protection
The zinc coating on hot dip galvanised panel tanks is formed by immersing the steel in a molten zinc bath at a temperature of around 450 degrees Celsius. The zinc reacts with the iron in the steel to form a tightly bonded alloy layer.
The alloy layer is impermeable to corrosive substances, such as water, oxygen, and acids. This prevents the corrosive substances from reaching the steel surface and causing corrosion.
Sacrificial protection
If the zinc coating on a hot dip galvanised panel tank is damaged, the zinc will corrode preferentially to protect the underlying steel. This is because zinc is more anodic than steel, meaning that it will corrode first in an electrochemical cell.
When the zinc corrodes, it forms a white layer of zinc oxide, which is also protective. The zinc oxide layer acts as a barrier between the steel and the environment, preventing further corrosion.
Benefits of hot dip galvanised panel tanks
Hot dip galvanised panel tanks offer a number of benefits over traditional tank materials, such as concrete and steel. These benefits include:
- Superior corrosion resistance: Hot dip galvanised panel tanks are highly resistant to corrosion, even in harsh environments.
- Long lifespan: Hot dip galvanised panel tanks have a long lifespan of up to 50 years.
- Low maintenance: Hot dip galvanised panel tanks require minimal maintenance.
- Environmental sustainability: Hot dip galvanised panel tanks are made from recycled materials and can be recycled at the end of their lifespan.
Applications of hot dip galvanised panel tanks
Hot dip galvanised panel tanks are used in a wide range of applications, including:
- Water storage: Hot dip galvanised panel tanks are ideal for storing water, both for drinking water and irrigation water. They are also used to store rainwater for harvesting and reuse.
- Wastewater storage: Hot dip galvanised panel tanks are also used to store wastewater for treatment and disposal.
- Chemical storage: Hot dip galvanised panel tanks are resistant to corrosion and can be used to store a variety of chemicals, including acids, bases, and solvents.
- Food and beverage storage: Hot dip galvanised panel tanks are non-toxic and can be used to store food and beverage products.
- Other applications: Hot dip galvanised panel tanks are also used in a variety of other applications, such as mining, oil and gas, and fire protection.
Conclusion
Hot dip galvanised panel tanks offer superior corrosion resistance, a long lifespan, and low maintenance requirements. They are also an environmentally sustainable choice for storage.
