High Capacity Liquid Asphalt Storage Tank System - Reliable China Suppliers & Factory for Road Construction Needs
Product Description
A liquid asphalt storage tank is a sealed steel tank used for long-term, large-capacity storage of high-temperature liquid asphalt. It is the core equipment for material storage, thermal insulation, and transfer in asphalt mixing plants, modified asphalt production lines, waterproofing membrane manufacturing, and the carbon industry, providing a stable source of asphalt for the entire production system.
Main Classification
By Structure
- ✓ Horizontal: Most commonly used, 5–100 tons, movable, fast installation.
- ✓ Vertical: Large fixed storage, 100–5,000 tons, for depots and large plants.
By Heating Method
- 🔥 Thermal oil circulation (Recommended): Uniform heating, no coking.
- 🔥 Fuel oil/gas direct: Fast temperature rise, suitable for remote sites.
- 🔥 Electric heating: Clean, suitable for small/waterproofing projects.
Core Structure (Three-layer Tank + Systems)
Inner Tank: Q235B carbon steel (6–10 mm), high-temperature corrosion resistant with internal thermal oil coils and localized rapid heating zones.
Insulation Layer: 100–150 mm high-density rock wool or aluminum silicate, aluminum sheet cladding. Temperature drop <1°C/h.
Outer Shell: Weatherproof carbon steel protective cladding for rain and sun protection.
Auxiliary Systems: Automatic temperature control (130–160°C), asphalt pump, feed/discharge piping, level/pressure gauges, breather valve, and optional mixing devices.
Key Technical Features
Common Specifications
| Small Job Sites | 5t, 10t, 20t Horizontal Tanks |
| Medium Mixing Plants | 30t, 50t, 80t, 100t Horizontal Tanks |
| Large Asphalt Depots | 200t–2000t Vertical Tanks |
Operating Principle
Hot liquid asphalt is fed into the tank from an asphalt melter or unloading system.
Internal coils maintain constant temperature to keep the asphalt in a fluid state.
Asphalt pump draws material from the bottom through filters for production delivery.
Impurities are periodically removed through the dedicated drain port at the tank bottom.
Difference from Buffer Tank
Storage Tank
Large capacity, designed for long-term storage and overall heating. Acts as the main material reservoir.
Buffer Tank
Small capacity, designed for short-term transfer, pressure stabilization, and degassing.
