What is Bitumen Tank?
Bitumen tank is a sort of industrial equipment specially designed for storing and transporting liquid bitumen and its mixtures with excellent structural strength and durability. Relying on the high-strength and highly corrosion-resistant metal materials used, bitumen tanks always have stable performance even in high temperatures or corrosive environments.

Main Roles of Bitumen Tank
1. Storage of Bitumen
Large capacity design and advanced sealing technology not only ensure safe storage of bitumen but also effectively prevent any possible leakage and external contamination, meeting the requirement of bitumen storage tanks specifications. This makes bitumen tanks the ideal choice for the storage of bitumen.
2. Transportation of Bitumen
Whether by road, rail or waterway, bitumen tanks deliver bitumen to its destination in a stable and efficient manner. This mode of transport enhances logistical efficiency and meanwhile significantly reduces the losses that can occur during transit. That’s why bitumen tanks occupy an important position in the whole transport sector.
Types of Bitumen Tanks
The diverse range of bitumen tanks can cater for the bitumen storage needs of different businesses.
1. Fixed and Mobile
In terms of mobility, there are fixed bitumen tanks and mobile bitumen tanks. The former can be firmly installed in the construction site, suitable for long-term storage, while the latter featuring lightweight and movability can meet the temporary or short-term storage needs, especially suitable for users who need to change their workplace frequently.
2. Horizontal and Vertical
Horizontal bitumen tanks and vertical bitumen tanks are divided by structural form. The former can be placed horizontally and has a large storage capacity, making it suitable for large-scale storage, while the latter needs to be installed vertically and can save floor space, so it is suitable for space-limited scenarios.
There are also bitumen tank container. Designed in combination with standard containers, they are easy to transport and stack, and hence are applicable to frequently moving scenes.
3. Direct Heating and Thermal Oil Heating
In accordance with the heating method, bitumen tanks are divided into the direct heating ones and thermal oil heating ones. The former can directly and efficiently heat bitumen, but the temperature control requirements are higher, whereas the latter are indirectly heated by thermal oil, which allows for more accurate temperature control, therefore suitable for users who require high-quality bitumen.
4. Storage-specific and Transport-specific
By purpose of usage, bitumen tanks can be further sub-divided into storage-dedicated bitumen tanks and transport-dedicated bitumen tanks. The former focuses on long-term, stable bitumen storage, while the latter is specially designed for bitumen transport to ensure the safety and stability during transportation.
5. Small, Medium and Large
Capacity is the most common way to classify tanks, typically measured in liters, gallons, or cubic meters. There is no universal standard, though following figures can give you a rough perception: up to 25,000 liters (small), 25,000 liters to 80,000 liters (medium), over 80,000 liters (large).
Besides capacity, mobility is a factor to consider when it comes to the bitumen tank size. Skid-mounted tanks for easy transport might be considered "small" even with a decent capacity, and permanently installed tanks would likely be considered "large" regardless of specific capacity.

Structure and Characteristics of Bitumen Tanks
1. Components of A Bitumen Tank
The main components of an asphalt tank include tank, heating system, insulation, level gauge and safety devices.
- Tank: Responsible for storing bitumen, with high strength and good sealing to prevent leakage and impurity intrusion.
- Heating System: Controls the heating temperature to keep the bitumen in the best working condition to fulfil the construction demand.
- Insulation layer: Advanced materials and designs are used with the aim of locking the heat, keeping the bitumen at a stable temperature and improving efficiency.
- Safety devices: Including explosion-proof, temperature control and emergency stop, etc. to ensure the safety of equipment and personnel.
2. Factors Affecting The Capacity of Bitumen Tank
The capacity of bitumen container is affected by factors such as tank size, thickness of insulation layer and efficiency of heating system.
3. Working Principle of The Bitumen Tank
The bitumen storage tank utilizes organic heat carrier (thermal oil) as the heat transfer medium, with coal, gas, or oil-fired burners as the heat source. The bitumen is heated to the required temperature through forced circulation by a thermal oil pump. With careful design and configuration, the heated bitumen is smoothly transported from the storage tank to the construction equipment or storage facilities.
1. Heating System: Typically located at the bottom of the tank, the heating system raises the bitumen to the desired temperature, achieved through direct combustion, thermal oil circulation, or electric heating.
2. Temperature Control: Temperature control is achieved through temperature sensors and control systems, ensuring precise regulation by operators to maintain optimal heating conditions.
3. Insulation: Insulation layers surround the tank, minimizing heat loss and aiding in the stabilization of internal temperatures.
4. Mixing System: Some bitumen tanks may feature mixing systems to prevent sedimentation and ensure uniform heating and mixing of the bitumen.
5. Safety Features: Safety valves, pressure gauges, and emergency shutdown mechanisms are employed to ensure safe operation and prevent overpressure situations.
6. Accessories: Additional components such as pumps, valves, and temperature monitoring devices contribute to the efficient operation and maintenance of the bitumen tank.
Application Scenarios of Bitumen Storage Tank
1. Asphalt Mixing Plant
Bitumen tank is one of the core components of asphalt mixing equipment and is used to properly store bitumen on-site, continuously supplying the pavement material producing device with the required base bitumen to enable the production of high-quality asphalt mixtures.
2. Bitumen Refining and Distribution
Bitumen tanks are the key to receiving, storing and delivering bitumen, thereby facilitating a smooth and efficient bitumen supply chain.
3. Building and Waterproofing
Bitumen is a key material, whether for paving roads, building car parks or waterproofing roofs.
