PTFE Lined Storage Tank for Corrosive Chemical Storage

Our PTFE lined storage tank is designed for safe and reliable storage of highly corrosive chemicals such as sulfuric acid, hydrochloric acid, nitric acid, and alkalis. By combining a strong carbon steel or stainless steel outer shell with a PTFE inner lining, the tank offers both mechanical strength and outstanding chemical resistance.

PTFE (Polytetrafluoroethylene) is widely known for its exceptional anti-corrosion properties and high temperature resistance, making it one of the most durable lining materials available.

Key Features of PTFE Lined Storage Tank

• Excellent chemical resistance against strong acids and alkalis

• Temperature resistance up to 150–180°C

• Non-stick and anti-scaling surface

• Long service life with minimal maintenance

• Strong mechanical support structure

• Customizable capacity and dimensions

Working Principle

The outer steel tank provides structural strength and pressure resistance, while the inner PTFE lining acts as a corrosion-resistant barrier. The lining prevents direct contact between stored chemicals and the metal shell, eliminating corrosion and extending the tank’s lifespan.

The PTFE lining is typically molded, sheet-lined, or spray-lined depending on tank size and application requirements.

Applications

PTFE lined storage tanks are widely used in:

• Chemical processing plants

• Pharmaceutical manufacturing

• Petrochemical industry

• Water treatment facilities

• Acid storage systems

They are especially suitable for storing:
