Products Description
A Stationary Vertical Asphalt Storage Tank is designed to store paving bitumen and specified grades of polymer-modified bitumen at controlled temperatures before transfer to asphalt mixing or road construction processes.
Key Features
Vertical Storage Design
Provides bulk storage within a defined ground footprint. Tank dimensions and foundation requirements are determined by storage capacity, site conditions, and project engineering.
Configurable Heating System
Thermal oil coils or electric heating options can be evaluated according to asphalt grade, required holding temperature, heating time, and available utilities.
Thermal Insulation
Mineral wool insulation with protective metal cladding is available to limit heat loss. Insulation thickness is selected according to thermal calculations and local ambient conditions.
Integrated Transfer Connections
Inlet, outlet, drain, vent, recirculation, and pump connections can be specified to suit the plant piping layout and operating requirements.

Heating System & Configuration
Thermal Oil Heating
Suitable for projects with a compatible thermal oil heating circuit. Coil arrangement and heating duty are determined by the required temperature rise, storage volume, heat loss, and available heat-source capacity.
Electric Heating
An option where the site has adequate electrical supply. Heater power, arrangement, temperature control, and over-temperature protection require project-specific sizing.
Insulation & Temperature Control
Insulation thickness, sensor locations, and control settings are selected according to the operating temperature, ambient conditions, asphalt grade, and required holding period.
Transfer & Circulation
Pump capacity, pipe diameter, valve arrangement, and pipeline heat tracing or jacketing are specified according to asphalt viscosity, transfer distance, flow rate, and operating temperature.
Manufacturing & Quality Control
Material Verification
Steel materials are checked against the specified grades and available mill test certificates before fabrication.
Welding & Inspection
Welding procedures, welder qualifications, visual inspection, and non-destructive testing are applied according to the approved design code and project inspection requirements.
Dimensional Inspection
Tank geometry, nozzle positions, flange alignment, and connection dimensions are checked against approved engineering drawings.
Surface Protection
External surface preparation, primer, and protective topcoat are selected according to the service environment and specified coating system.
Inspection Documentation
Material records, dimensional inspection results, weld inspection reports, and test documentation can be specified in the project quality plan.
Applications & System Integration
Asphalt Mixing Plants
Provides a storage buffer for bitumen supply to batch or drum mix asphalt production systems.
Road Construction Projects
Supports on-site storage for paving operations, subject to project capacity and heating requirements.
Bitumen Processing & Distribution Terminals
Can be configured for storage between delivery, processing, and subsequent transfer to tankers or other process equipment.
Plant Integration Requirements
Heating utilities, pump specifications, pipeline heating, electrical supply, access platforms, venting, level monitoring, and safety provisions should be coordinated before fabrication.

Frequently Asked Questions
Q: What capacity is available for a stationary vertical asphalt tank?
A: Capacity is determined by the project storage requirement and site conditions. The 30–150 m³ range is a preliminary reference; other capacities require engineering review.
Q: Which heating method should I choose?
A: Thermal oil heating and electric heating are possible configurations. Selection depends on the required heating duty, available utilities, asphalt grade, and operating schedule.
Q: Can the tank store polymer-modified bitumen?
A: Yes, provided the tank heating, temperature monitoring, insulation, and transfer arrangements are suitable for the specified polymer-modified bitumen grade and its handling requirements.
Q: Can the tank be integrated with an existing asphalt plant?
A: Yes, subject to confirmation of the existing plant's piping, pump capacity, heating utilities, electrical interfaces, control signals, and installation constraints.
Q: Which design standards apply?
A: Applicable standards depend on the tank design, operating conditions, installation location, and jurisdiction. The governing design code and inspection requirements should be agreed before fabrication.
