Liquid Asphalt Transportation System - Reliable High-Temperature Conveying Solutions from China Suppliers & Factory
Product Description
The liquid asphalt transportation system is a complete set of transportation equipment that safely, continuously and stably transports the high-temperature liquid asphalt from storage tanks and melting devices to various production stations. Throughout the process, insulation, temperature control, anti-solidification and anti-blockage measures are required. It is the "blood vessel" of the asphalt production line.
Main Functions of the System
Continuous Transportation
Enables the asphalt to be transported from the melting tank, storage tank to the buffer tank, filter, heater, and finally to the production equipment throughout the process.
Thermal Insulation & Anti-condensation
Ensure that the asphalt temperature remains stable during transportation, without solidification or increased viscosity.
Stable Pressure & Flow
Provide stable pressure and flow for metering, spraying, impregnation, and mixing.
Safety & Sealing
Reduce the volatilization of smoke, prevent leakage, scalding, and fire hazards.
Core Components
- Common types: asphalt gear pump, screw pump, centrifugal pump
- Function: Provide power to overcome pipeline resistance and transport hot asphalt
- Seamless steel pipe, smooth inner wall to reduce resistance and coking
- Heating and insulation system: Heat transfer oil heating, steam heating or electric heating
- Wrapped with external insulation layer to prevent temperature drop
- Specialized asphalt-specific valves, ball valves, gate valves
- All with heating to prevent jamming and blockage
- Filter: impurity removal protection pump and instruments
- Buffer tank: pressure stabilization, elimination of pulsation
- Flow meter: measurement and ratio control
- Temperature and pressure monitoring and control system
Work Flow (Typical)
Operating Characteristics
Working temperature: 130℃ - 200℃
The entire process is sealed and heated, and there should be no "cold spots"
Starting and stopping require preheating and heating before starting the pump; stopping requires purging or maintaining a temperature-controlled circulation
Suitable for continuous and automated production lines
