Mali customers repeatedly negotiated with our technical team through online meetings and clearly proposed the need to purchase 15 oil tank semi-trailers for cross-border transportation of refined oil. After an in-depth analysis of Africa's high-temperature road conditions and long-distance transportation needs, our company recommended a 40-cubic-meter three-axle oil tank semi-trailer. This model uses a double-layer vacuum insulated tank body and an intelligent pressure monitoring system, which can transport gasoline and diesel at the same time, and has outstanding performance in safety and multi-media compatibility. After the customer confirmed the design plan through a 3D model demonstration, the project cooperation was officially launched.
In order to ensure the compliance of oil transportation, the customer sent the technical director to the Liangshan production base in Shandong to inspect the production process of core components such as explosion-proof manhole covers and emergency shut-off valves. The two parties jointly completed the full-load rollover test and electrostatic release test at the plant test site, and finally reached a technical consensus on the tank material standard (using WDB620 high-strength steel) and compliance with the European standard ADR certification standard, and signed the first batch of orders.
The oil tank semi-trailers exported to Mali adopt a honeycomb compartment structure, with 8 sets of built-in wave-breaking plates, and the tank body is divided into 6 independent spaces. Equipped with high-precision liquid level sensors, it can realize the simultaneous transportation and real-time monitoring of multiple oil products. In view of the large temperature difference between day and night in Africa, the tank body is covered with a nano-aerogel insulation layer to ensure that the temperature fluctuation of the oil does not exceed ±2℃.
In terms of safety protection system, the vehicle is equipped with triple safety guarantees:
The explosion-proof breathing valve on the top of the tank is made of titanium alloy and can maintain stable operation in a high temperature environment of 60°C
The response time of the emergency cut-off device at the bottom is less than 0.8 seconds, which is 40% higher than the industry standard
The electrostatic removal system is equipped with a copper belt grounding chain to ensure that the resistance value per kilometer is less than 4Ω
Its intelligent unloading system is particularly outstanding, integrating hydraulic drive and Internet of Things modules, and supporting remote control of multi-position precise oil unloading. According to actual measurements, 35m³ of oil in a single warehouse can be discharged without residue within 7 minutes, and the operating efficiency is 60% higher than that of traditional models. The hydraulic pump station is specially equipped with a dual redundant system, which can work continuously for 200 hours without failure even in sandstorm weather.
The surface of the tank adopts a military-grade composite coating process, with the bottom epoxy zinc-rich primer and the surface polyurethane fluorocarbon paint forming a double protection, and the ability to resist salt spray corrosion is more than 3,000 hours. With a detachable anti-collision guardrail, it is suitable for mechanical loading and unloading operations in Mali ports, and can effectively resist scratches from hard objects such as branches and rocks during transportation.
