Supplied Equipment: Vertical / Horizontal Asphalt Storage Tanks, Thermal Oil Heating System, Thermal Insulation & Protection Structure, Asphalt Transfer Pipelines, Intelligent Temperature Control System, Liquid Level Monitoring System, Safety Pressure Relief and Anti-Seepage Supporting Systems (Customizable volume, material and explosion-proof configuration for export projects) Project Objective: To build a stable and reliable constant-temperature asphalt storage system, maintain asphalt fluidity and prevent asphalt aging, coking and solidification. It meets the continuous feeding requirements of the asphalt storage base, complies with local environmental protection and safety regulations, and supports remote monitoring and low-energy operation.

Customer Pain Points The original storage tanks suffer from poor thermal insulation, massive heat loss and high energy consumption. Insufficient temperature control accuracy leads to asphalt deterioration and aging at excessive temperatures, or asphalt solidification and pipeline blockage at low temperatures. Lack of reliable liquid level and pressure monitoring brings high safety risks. Weak anti-corrosion performance of the tank shell results in a short service life. Manual on-duty operation is cumbersome and cannot guarantee stable and continuous feeding, disrupting the production rhythm of the mixing plant. Our Solution Carbon steel tank body with internal and external anti-corrosion coatings is adopted, equipped with thickened rock wool insulation layer and outer cladding panels. Zoned heating via thermal oil coils together with PLC intelligent temperature control realizes automatic constant temperature, with high/low temperature alarm functions. It is fitted with liquid level gauges, pressure safety valves, emergency discharge and anti-seepage collection structures. Integrated remote data acquisition module enables real-time viewing of temperature, liquid level and operating status. The equipment is manufactured in modular form with factory prefabrication for fast on-site assembly and commissioning. Export packaging, technical briefing and operation & maintenance training are provided. Project Outcomes The asphalt storage temperature is stably controlled, effectively preventing asphalt aging, caking and pipeline blockage. The insulation system greatly cuts heating energy consumption and reduces operating costs. A complete set of safety monitoring and interlock devices improves on-site safety production. Stable asphalt conveyance is achieved to ensure continuous operation of the mixing production line. The equipment features good anti-corrosion property and long service life to meet the requirements of long-term stable operation of the project, and has passed acceptance smoothly.
