A Metal Asphalt Hose is a specially engineered metal flexible pipe designed for the safe and efficient transfer of asphalt, bitumen, pitch, and other high-temperature viscous materials. Unlike rubber or composite hoses, metal asphalt hoses are built entirely from metal materials, making them ideal for extreme temperature, pressure, and harsh operating environments.
These hoses are widely used in road construction, asphalt mixing plants, bitumen storage systems, tanker loading/unloading, and industrial heating pipelines, where reliability and safety are critical.
Why Metal Asphalt Hose Instead of Rubber Hose?
Asphalt and bitumen are typically transported at high temperatures (160–220°C or higher). Conventional rubber hoses are prone to aging, hardening, cracking, or swelling under such conditions.
Metal asphalt hoses eliminate these risks by offering:
Excellent resistance to high temperature
No risk of rubber degradation or delamination
Longer service life in continuous hot-media applications
Higher safety margin for heavy-duty operations
Structure and Design
A typical metal asphalt hose consists of:
Inner Metal Corrugated Tube
Usually made from stainless steel, providing flexibility while maintaining structural strength and smooth flow for viscous media.Outer Reinforcement Layer (Optional)
Single or double stainless-steel wire braiding can be applied to enhance pressure resistance and mechanical protection.End Connections
Flanges, threaded fittings, or customized connections are available to match asphalt tanks, pumps, heaters, and pipelines.
The corrugated metal structure allows the hose to absorb thermal expansion, vibration, and slight misalignment, making it suitable for dynamic working conditions.
Key Performance Advantages
High-Temperature Resistance
Designed for continuous operation with hot asphalt and bitumen without material degradation.High Pressure Capability
Suitable for pumping and circulation systems in asphalt plants and tanker applications.Excellent Chemical Resistance
Resistant to petroleum-based products, bitumen additives, and cleaning media.Mechanical Strength & Flexibility
Maintains flexibility while offering superior resistance to crushing, abrasion, and external impact.Long Service Life
Reduced maintenance and replacement frequency compared to non-metal hoses.
Typical Applications
Metal asphalt hoses are commonly used in:
Asphalt mixing plants
Bitumen storage and heating systems
Road construction equipment
Asphalt tanker trucks and terminals
Industrial pipelines handling hot viscous fluids
They are especially suitable for loading and unloading asphalt, circulation of heated bitumen, and connections between heaters, pumps, and storage tanks.
Customization Options
To meet different project requirements, metal asphalt hoses can be customized in terms of:
Hose diameter and length
Corrugation type and flexibility level
Single or double wire braiding
End fitting standards and sizes
Working temperature and pressure ratings
Our engineering team works closely with customers to ensure each hose is optimized for its actual operating conditions.
