Product Description
Double-walled fuel tanks are specialized storage containers for fuel, featuring leak prevention and corrosion resistance, making them widely used in the petroleum, chemical, food, medical, wastewater treatment, energy, and agricultural industries. Here is a detailed introduction to double-walled fuel tanks:
I. Definition and Classification
Double-walled fuel tanks primarily consist of three types: SS, SF, and FF.
- SS Storage Tank: Fully known as Steel Strengthened Double-walled Storage Tank, it comprises an inner steel tank and an outer steel tank, with a uniform interstitial space between them. Equipped with leak detection instruments.
- SF Storage Tank: Known as Steel Fiberglass Reinforced Plastic (FRP) Double-walled Storage Container, it adds an FRP (or fiberglass) anti-leakage outer jacket to a single-walled steel tank, creating a double-walled structure.
- FF Storage Tank: Fully known as Fiberglass Reinforced Plastic Double-walled Fuel Tank, both the inner and outer layers are made of FRP, with an interstitial space between them.
II. Structure and Characteristics
- SF Double-walled Fuel Tank Structure
- Inner Layer: Made of 6mm thick Q235-B steel plate, providing higher strength compared to single-walled tanks.
- Outer Layer: Reinforced fiberglass layer, over 2.5mm thick, offering excellent compressive, seismic, corrosion, and electrical erosion resistance.
- Interstitial Space: Between the steel inner tank and FRP outer tank, ranging from 0.1 to 3.5mm, without solid support.
- Reinforced Structure: Inner tank reinforcement for enhanced overall stability.
- Detection Equipment: Equipped with leak detection instruments for 24/7 monitoring of the interstitial space, triggering alarms upon detecting liquid level changes.
- FF Double-walled Fuel Tank Structure
- Inner and Outer Layers: Both made of FRP, with thicknesses not less than 4.5mm and 4mm respectively. The outer wall has integrated reinforcing ribs for structural strength.
- Interstitial Space: Complete 360° interstitial space, occupying 0.2% to 2% of the tank's capacity, with solid support.
- Detection Equipment: Also equipped with leak detection instruments for continuous 24/7 monitoring, compatible with vacuum or pressure detection as primary detection equipment.
III. Working Principle
Double-walled fuel tanks provide additional protection and isolation layers through their double-wall construction, ensuring the safety of stored petroleum products. The outer wall offers mechanical protection against external damage to the inner tank, while the inner tank contains the fuel, preventing contact with the external environment. The interstitial space between the layers provides insulation and isolation, minimizing temperature fluctuations' impact on the stored fuel. Safety features such as level, temperature, pressure monitoring, and leak detection ensure the tank's smooth operation and safety.
IV. Advantages and Applications
Advantages
- High Safety: The double-wall structure effectively prevents leaks, ensuring that even if the inner layer leaks, the hazardous material remains within the interstitial space, preventing environmental contamination.
- Environmental Friendliness: The outer layer's corrosion resistance prevents electrolytic corrosion with groundwater, and the leak detection system monitors 24/7 to eliminate pollution risks.
- Economic Efficiency: Long service life and low maintenance requirements reduce operational costs. Easy installation shortens project timelines and further cuts costs.
Applications
- Petroleum Industry: For petroleum storage and transportation, ensuring product safety and environmental protection.
- Chemical Industry: Storing various chemical liquids and gases, safeguarding the environment and human health.
- Food Industry: Storing oils, beverages, and other food ingredients, preserving product quality.
- Medical Industry: Keeping drugs, vaccines, and other sensitive materials safe and contamination-free.
- Wastewater Treatment Industry: Collecting and separating oily wastewater, protecting the environment.
- Energy Sector: Widely used in energy storage and transportation, ensuring energy security.
- Agriculture: Storing liquid fertilizers, pesticides, and other agricultural materials, minimizing environmental pollution.
In conclusion, double-walled fuel tanks play a crucial role in various industries due to their unique structure and advantages, making them a top choice for modern fuel storage equipment.
