High Temperatures Intensify Corrosion: Material and Lining Design in Acid Tanker Trucks Under Industry Focus

In many regions across Africa, particularly in mining and chemical zones, ambient temperatures often exceed 30°C. Under such conditions, corrosive media like sulfuric acid can react more aggressively with metal surfaces, accelerating material degradation.
This has brought increased attention to material selection and internal lining design in acid and alkali tanker trucks.

Carbon steel, such as Q235, is commonly used for tanker construction due to its structural strength (typically around 5 mm for the shell and 6 mm for the head). However, when transporting highly corrosive liquids, it requires an effective internal lining system to prevent direct exposure.

Under high temperatures and long transport cycles, lining thickness plays a critical role. For example, a 16 mm PE lining can act as a stable barrier between the acid and the steel structure, reducing corrosion risks.
Equally important is the uniformity and bonding quality of the lining, which affect long-term durability.

Leakage risks are often concentrated in the piping system. The use of fluorine-lined valves, such as 4-inch bottom valves and 3-inch discharge valves, provides enhanced resistance in areas directly exposed to corrosive media.

In copper and gold mining, sulfuric acid is widely used in leaching processes. Transport routes from mining sites to processing plants are often long and involve challenging road conditions, requiring stable tanker structures and controlled liquid movement.

In fertilizer production, sulfuric acid is a key raw material. High-frequency transport demands emphasize equipment durability and reduced maintenance intervals, ensuring continuous operation.

A combination of carbon steel structure with thick PE lining offers a balance between mechanical strength and corrosion protection.

Tankers equipped with internal baffles (e.g., three-wave breaker plates) help reduce liquid surge during transport, improving stability over long distances.

• Anti-static grounding devices to reduce electrostatic risks
• Liquid level monitoring systems (e.g., ultrasonic level gauges)
• Advanced braking systems (e.g., EBS) for improved control

As industrial demand grows across Africa, acid tanker trucks are evolving from basic transport equipment to systems emphasizing durability, safety, and adaptability. Clearly defined material specifications and structural design parameters are expected to play a more critical role in future procurement decisions.
