What are poly fuel tanks made of?
Poly fuel tanks are typically made from high-density polyethylene (HDPE), a durable and lightweight plastic known for its chemical resistance and strength. Some tanks may also have multi-layer construction for added protection.
Are poly fuel tanks safe for storing diesel or petrol?
Yes. Modern poly fuel tanks are designed to safely store diesel, petrol, and other compatible fuels. They resist rust and corrosion, making them ideal for long-term use in various environments.
How long do poly fuel tanks last?
With proper care, poly fuel tanks can last 15 to 20 years or more. Tanks that are UV-stabilised and regularly maintained tend to have a longer lifespan, even in harsh outdoor conditions.
What are the pros and cons compared to steel tanks?
Advantages:
- Lightweight and easy to handle
- Corrosion-resistant
- Typically more affordable
Do poly fuel tanks need internal linings or barriers?
For diesel and petrol, most poly tanks made from HDPE are sufficient without additional linings. However, some applications may require barrier layers to reduce vapour permeation or meet specific regulations.
Can poly fuel tanks be used for other fluids?
Yes. Poly tanks are suitable for storing a wide range of liquids, including petrochemicals, water, oil, and certain chemicals. Always verify compatibility before use.
Are poly fuel tanks repairable if damaged?
Yes. Many poly tanks can be repaired using plastic welding techniques or by replacing damaged fittings, depending on the tank’s design and material.
What maintenance do poly fuel tanks need?
Routine maintenance includes:
-
- Inspecting for cracks or UV damage
- Draining water and sediment if present
- Checking fittings and seals
- Keeping the tank shaded when possible
