Bitumen, often referred to as asphalt binder, is a dark, sticky, highly viscous hydrocarbon derived from crude oil refining. For the material to be handled, pumped, and used effectively in paving and construction applications, it must be stored and transported at elevated temperatures, typically well over [Omitted specific numerical value] degrees Fahrenheit. The storage of this high-temperature, highly viscous material presents unique engineering challenges that govern the entire tank design:
Extreme Thermal Management: The tank must reliably and efficiently maintain a high, uniform temperature to ensure the bitumen remains in a liquid, pumpable state, preventing solidification and operational failure.
Structural Integrity Against Viscosity: The tank structure, particularly internal components and connections, must withstand the immense force and drag exerted by the highly viscous liquid during heating, mixing, and pumping operations.
Heat Transfer Efficiency: The heating system must be designed for maximum fuel efficiency and minimum risk of localized overheating (coking) of the bitumen, which can degrade the product and damage the heating elements.
The industry-standard solution for high-volume, continuous thermal storage is the custom-engineered welded steel tank. Its monolithic structure provides the necessary structural resilience to manage both the high thermal stress and the physical demands of the viscous product, while offering the versatility to integrate complex heating systems.
Shijiazhuang Zhengzhong Technology Co., Ltd, known globally as Center Enamel, leverages its deep experience in high-integrity steel fabrication and specialized quality management to excel as a China Bitumen Tanks Manufacturer. We deliver custom-engineered welded steel tanks that strictly adhere to relevant international codes, such as those set by the American Petroleum Institute (API [Omitted specific numerical value]) and various thermal process engineering standards. Our commitment ensures our clients receive storage assets engineered for maximum thermal efficiency and operational longevity in the demanding infrastructure sector.
The design and manufacture of Bitumen Tanks are fundamentally driven by the necessity of precise thermal control, managing high internal viscosity, and ensuring safety. Our expertise in specialized welded tank fabrication ensures every critical aspect is addressed, guaranteeing reliability across terminal, refinery, and road construction environments.
Maintaining a uniform, elevated temperature is the primary function of a bitumen storage tank. Our designs focus on efficiency and product quality preservation.
Integrated Heating Systems (Thermal Fluid or Direct): Our Bitumen Tanks are custom-designed with highly efficient heating systems. The most common is the use of thermal fluid (hot oil) circulated through internal pipe coils. These coils are strategically placed near the tank floor and around the pump suction points, ensuring uniform heat distribution and maintaining pumpable viscosity. Direct heating systems (e.g., electric resistance elements) are also precisely integrated where required.
Heating Coil Design and Spacing: The geometry, spacing, and surface area of the heating coils are carefully calculated to prevent localized overheating of the bitumen, which leads to coking—a process that degrades the product and reduces the efficiency of the heating element. Our precision welded coil systems maximize heat transfer while minimizing coking risk.
External Insulation and Cladding: To drastically minimize heat loss and maximize energy efficiency, all tanks are fitted with robust thermal insulation systems (often mineral wool or specialized foam). This insulation is protected by a durable, weather-resistant external cladding (typically aluminum or galvanized steel), ensuring the required operational temperature is maintained with minimal energy consumption.
The highly viscous nature of bitumen exerts significant drag and pressure on internal components, especially during filling and pumping.
Robust Welded Construction: We utilize certified, high-grade steel, processed and joined using advanced, automated welding procedures. The commitment to full-penetration, leak-proof welding ensures the monolithic welded tank structure provides a reliable barrier against high hydrostatic pressure and the physical stresses induced by the viscous product.
Structural Support for Heating Systems: The internal structure, including the supports for the heating coils and the thermal fluid piping, is meticulously welded to the tank shell and floor. These connections are engineered to withstand the thermal expansion/contraction cycles and the immense drag created by the bitumen, preventing internal failure.
Slope and Drainage: The tank floor is engineered with a slight slope towards the drain or pump suction point. This prevents dead zones where cold spots could develop and facilitates complete drainage during maintenance or product changeover.
The tanks are designed to be an integrated, functional part of the logistics chain, focusing on reliable transfer and environmental safety.
Pump Suction Heating: The most common point of failure is the pump suction line, where bitumen can cool and solidify. Our tanks feature a dedicated, isolated heating system for the pump suction box (often called a "hot well") to ensure the bitumen is always at the required temperature for immediate and continuous pumping.
Safety Vents and Hatches: Given the high temperatures, tanks are equipped with specialized pressure/vacuum relief vents to manage thermal expansion and prevent structural overstress. Large access hatches are provided for inspection and maintenance, fabricated with high-integrity seals to minimize heat loss.
Level Monitoring and Alarms: Tanks are fitted with precision instrumentation ports for continuous level monitoring, high-temperature alarms, and automatic shutdown systems to prevent hazardous conditions.
While bitumen itself is not highly corrosive, water ingress and the nature of the heating systems can introduce corrosive factors.
External Protective Coatings: Tank exteriors receive multi-layer, high-performance coating systems tailored to resist UV exposure, weathering, and industrial atmosphere corrosion, protecting the structural steel shell.
Material Selection for Coils: Heating coils are often fabricated from specialized alloys or high-strength steel to resist thermal stress and potential corrosion from the circulating thermal fluid. The integrity of the welded joints on these coils is tested rigorously to prevent leaks.
Foundation Integrity: Tanks are designed to be mounted on robust concrete ring beam foundations, protecting the tank floor from ground moisture and facilitating inspection of the tank bottom.
