Products Description
Large Capacity Bitumen Tank is the core storage equipment for road engineering and asphalt mixing plants, mainly used for mass storage of high‑temperature liquid asphalt. Mostly manufactured from carbon steel, it is available in vertical and horizontal configurations with a wide range of single‑tank capacities to meet continuous material‑supply demands for large‑scale storage yards and mixing plants. Equipped with thermal‑oil heating coils internally and wrapped with thermal insulation layers externally, the tank maintains a stable operating temperature for asphalt to prevent solidification, aging and caking, and ensure smooth discharging. Widely applied in highway construction, modified‑asphalt production and asphalt storage depots, it achieves high storage‑and‑turnover efficiency, supports continuous and stable production for engineering projects, and lowers the risk of material‑supply interruptions.
Product Structure
Outer Protection Layer
High‑strength metal plates form the outer tank body to resist wind, rain and external impacts, and protect the internal thermal‑insulation structure.
01
Thermal Insulation Layer
High‑performance thermal‑insulation material fills the middle layer, greatly blocking internal‑external heat transfer and slowing down internal heat loss.
02
Inner Storage Chamber
Temperature‑resistant and anti‑corrosion materials form the inner cavity in direct contact with asphalt. Its smooth surface minimizes asphalt adhesion and residual buildup.
03
Temperature Control System
Evenly distributed heating and temperature‑measuring components are installed inside to detect tank temperature in real time and activate heating as required to maintain a constant temperature.
04
Auxiliary Operating Components
Manholes, discharge valves, vent valves and other accessories are provided to support full‑process operations including feeding, discharging, maintenance and ventilation.

Process Technology
Plate Pre‑treatment
Tank plates undergo rust removal and passivation pre‑treatment to improve corrosion resistance from the source and prevent rust penetration in later service.
Integrated Welding
Continuous hermetic welding is adopted. All tank welds are anti‑seepage treated to avoid medium leakage during long‑term service.
Thermal‑Insulation Filling
Gap‑free integral filling technology ensures thermal‑insulation material fully fills the interlayer and avoids local voids that would compromise insulation performance.
Application Scope
Road Construction: Suitable for various highway construction sites. It provides on‑site large‑capacity asphalt storage and temperature control for paving operations.
Building‑Material Storage & Transportation: Applicable to asphalt storage and transfer stations for bulk storage of asphalt products pending distribution and maintaining stable medium conditions during transit.
Municipal Maintenance: Ideal for urban‑road maintenance units to store asphalt for daily pavement repair. On‑demand material access improves maintenance efficiency.
Mixing Plant Matching: Matches asphalt concrete mixing plants by supplying stable hot asphalt for mixing procedures and ensuring a continuous production rhythm.
Field Engineering: Suitable for remote field road‑and‑bridge projects. It supports long‑time insulated asphalt storage independently without frequent heat‑source replenishment.
Operation Instructions
Pre‑heat the tank cavity before initial feeding. Avoid injecting hot asphalt into a cold tank, as this may cause local temperature drop and solidification.
Set the temperature control range according to process requirements during operation. Avoid prolonged over‑temperature heating to reduce unnecessary performance loss.
Activate local heating systems before discharging to pre‑heat asphalt around discharge outlets to a flowable state, then open valves for discharging.
Carry out regular inspections of tank temperature and sealing status, and record operating parameters to detect potential hidden risks in advance.
Drain residual asphalt and clean and dry the interior for long‑term idling to prevent cured medium from adhering to inner walls.
