Product Overview
Bulk bitumen storage terminal tanks are engineered for storing, heating and transferring paving bitumen at ports, distribution depots and asphalt production facilities. System configuration depends on storage capacity, bitumen grade, operating temperature, throughput and site conditions.
Large-Capacity Storage: Vertical or horizontal tanks can be selected according to inventory requirements, available footprint and installation constraints.
Integrated Heating and Transfer: Thermal-oil heating, insulated piping, transfer pumps and instrumentation can be specified to suit the required operating conditions.
Project-Based Engineering: Tank dimensions, materials, heating duty, connections and control functions are defined according to the approved design basis.
Flexible Supply Scope: Supply can be specified for individual tanks, tank groups or integrated storage and transfer systems, subject to confirmed engineering and project scope.
Tank Configurations & System Selection
Tank Structure
Vertical Bitumen Storage Tanks: Suitable for large storage volumes where site layout, foundation design and available height support vertical installation.
Horizontal Bitumen Storage Tanks: Suitable for smaller storage installations, distribution depots and sites with specific layout or installation constraints.
Multi-Tank Terminal Systems: Multiple tanks can be configured for separate bitumen grades, inventory management and planned maintenance, with transfer arrangements defined during engineering.
Heating & Insulation
Thermal-Oil Heating: An indirect heating option using a circulating heat-transfer fluid and a suitably designed heating circuit.
Electric Heating: An alternative for projects where electrical supply, required heating duty and operating costs support this configuration.
Thermal Insulation & Cladding: Mineral wool or another specified insulation system can be selected according to heat-loss calculations, operating temperature and ambient conditions.
Transfer & Control
Heated Transfer Pipelines: Jacketed or heat-traced piping can be specified to maintain the required bitumen temperature during transfer and standby periods.
Pumps & Manifolds: Pump type, capacity, connections and routing are selected according to bitumen viscosity, required flow rate and system pressure losses.
Monitoring & Protection: Level instruments, temperature sensors, alarms and shutdown interfaces can be incorporated according to the project control philosophy and risk assessment.

Heating, Insulation & Operating Requirements
Heating Duty Calculation: Heating capacity is determined by the initial and target bitumen temperatures, required heat-up time, tank contents, ambient conditions and thermal losses.
Temperature Management: Instrumentation and control settings are specified according to the bitumen grade and project operating requirements. Maximum allowable temperatures must be confirmed for the stored material.
Heat-Loss Control: Insulation materials and thicknesses are selected through thermal calculations rather than assumed percentage savings.
Transfer-Line Temperature Maintenance: Pipeline insulation, tracing or jacketing, together with suitable pump and valve arrangements, is evaluated to address cooling and solidification risks.
Manufacturing & Quality Control
Inspection and documentation requirements should be defined in the project quality plan and aligned with the applicable design code.
Material Traceability: Material certificates and identification records are reviewed against approved material specifications and traceability requirements.
Welding Quality: Welding procedures, welder qualifications and inspection requirements are established according to the governing code and approved inspection plan.
Non-Destructive Testing: Visual inspection and applicable methods such as radiographic testing (RT), ultrasonic testing (UT) or penetrant testing (PT) are specified according to the relevant weld category and code requirements.
Tank & Piping Testing: Tank testing and piping pressure or leak testing are defined separately according to the applicable design, construction and testing requirements.
Handover Documentation: The agreed documentation package may include approved drawings, material certificates, welding records, NDT reports, test records and operation and maintenance manuals.

Frequently Asked Questions
Q: How do I determine the required tank capacity?
A: Start with peak demand, delivery intervals, inventory policy and replenishment lead time. Calculate usable storage volume rather than relying solely on nominal tank capacity, and account for operating limits and unusable volume.
Q: Which heating method should I select?
A: Thermal-oil and electric heating should be evaluated against heating duty, energy availability, operating schedule, maintenance requirements and lifecycle cost. The appropriate choice depends on the specific project rather than a universal capacity threshold.
Q: How can bitumen solidification in transfer lines be addressed?
A: Pipeline insulation, heat tracing or jacketing, suitable pump selection and temperature monitoring can be incorporated according to the bitumen properties and operating conditions. Standby and shutdown procedures should also be considered.
Q: Can different bitumen grades be stored in one terminal?
A: Yes. A multi-tank layout can accommodate different grades when tank allocation, piping segregation, valve arrangements and transfer procedures are appropriately specified. PMB and other specialized materials require a compatibility and handling review.
Q: What inspection and handover documents are available?
A: The required package can be defined in the purchase specification and may include material certificates, welding records, NDT reports, applicable tank and piping test records, approved drawings and operating manuals. Availability and scope should be confirmed before contract award.
