Tank truck aluminum plate

What is tank truck aluminum plate

“Tank truck aluminum plate” is a special aluminum alloy plate, which refers to the aluminum alloy plate used to manufacture the main structure or internal storage tanks of tank trucks (such as oil tank trucks, liquefied gas tank trucks, chemical transport tank trucks, etc.). This type of aluminum plate needs to have specific performance characteristics to meet the safety and durability requirements of tank trucks during transportation.

Tank truck introduction

Tank truck is a transport vehicle with a tank-shaped body, used to carry various liquids, liquefied gases, powdery goods, etc. The body of the aluminum alloy tank truck is composed of side panels, fenders, tank mouth and other parts.

The aluminum plates commonly used for tank trucks on the market are generally less than 12.5 meters in length and less than 2.2 meters in width. Common thicknesses are 5mm, 6mm, 7mm, and 8mm. A complete tank truck body usually requires 4-6 aluminum plates welded together.

Common alloys for tank truck aluminum plates

Specific applications of tank truck aluminum plates

The can body is made of 5083-H111 aluminum plate, and the lids on both sides are made of 5083-O aluminum plates. The O-temper is softer, but the lid needs to be bent, and the partition part is also made of 5083-O. In addition, some manufacturers use 5454-H111 aluminum plates to produce tanks.

Why use tank truck aluminum plate

• Light weight: The density of aluminum alloy is only one-third that of steel, so tank trucks made of aluminum plates are lighter than those made of steel. This means that aluminum alloy tank trucks can carry more goods, thereby improving transportation efficiency.
• Strong corrosion resistance: Aluminum alloy has good corrosion resistance, which gives aluminum alloy tank trucks an advantage when transporting chemicals or other corrosive substances.
• Long service life: Due to the corrosion resistance of aluminum alloys, aluminum alloy tank trucks usually have a longer service life than steel tank trucks.
• Beautiful appearance: The surface of the aluminum alloy tank truck is smooth and the color is bright, giving people a high-end and professional feeling.
• Superior performance: Aluminum alloy tank trucks have high hardness and good weldability, which makes aluminum alloy tank trucks more flexible in the manufacturing process and can meet various complex design requirements.
• High safety: Aluminum alloy can absorb more energy in a collision, so aluminum alloy tank trucks can provide better protection in the event of an accident.
• High recycling value: The recycling value of aluminum alloy is higher than that of steel, so even if the tanker is scrapped, it can be recycled and used to reduce waste.

Instructions for purchasing and using aluminum plates for tank trucks

How to avoid welding failure of aluminum plate of tank truck

• Choose the appropriate welding method: Choose the appropriate welding method for different aluminum plate materials and thicknesses, such as MIG (metal inert gas welding), TIG (argon arc welding), or resistance welding, etc.
• Select appropriate welding materials: Select welding materials that meet the requirements. Usually, the same or similar alloy materials as the aluminum plates are used for welding to ensure that the weld performance meets the requirements.
• Control welding parameters: Strictly control welding current, voltage, welding speed and other parameters to ensure welding quality.
• Preheating and post-heat treatment: For thicker aluminum plates or welding parts with special requirements, appropriate preheating and post-heat treatment can be performed to reduce welding stress and avoid cracks.
• Keep the welding environment clean and dry: Keep the welding environment clean during the welding process to avoid impurities such as oil, water vapor, etc. from entering the welding area and affecting the welding quality.
• Avoid excessive welding: Avoid excessive welding time or high welding temperature to avoid excessive thermal deformation of the aluminum plate or hardening of the weld area, which will affect the welding quality.
• Quality control: Implement strict quality control measures, including monitoring and testing of the welding process, to ensure that the welding quality meets the requirements.
• Training and technical support: Provide training to welding operators to improve their welding technical level. At the same time, they can seek professional welding technical support to solve problems encountered during the welding process.

How to reduce corrosion of aluminum alloy tanks?

Alloy selection and optimization:

Choose corrosion-resistant aluminum alloys: Choose aluminum alloys containing appropriate amounts of magnesium, manganese, chromium, silicon and other elements, such as 5000 series aluminum alloy (containing magnesium), 6XXX series (containing magnesium and silicon) or part of the 7XXX series (containing zinc). These alloys have Better natural corrosion resistance.

Alloy purity: Improving the purity of aluminum alloys and reducing the content of impurity elements, especially iron, copper and other elements that easily cause corrosion, will help improve the overall corrosion resistance.

Surface treatment:

Anodizing: Anodize the surface of aluminum alloy to form a dense aluminum oxide film (Al₂O₃) to improve its corrosion resistance and wear resistance. The color of the anodized film can be controlled by adjusting process parameters, and has a good decorative effect.

Special coating: Select special coating suitable for aluminum alloy, such as epoxy resin, polyurethane, fluorocarbon coating, etc., to ensure good adhesion and anti-corrosion performance between the coating and the aluminum alloy substrate. Coatings should have good chemical resistance, weather resistance and mechanical properties.

maintenance:

Regular inspection: Establish a regular inspection system to conduct visual inspection, thickness measurement, corrosion monitoring, etc. on the surface of the tank to promptly detect and repair coating damage and corrosion signs.

Cleaning and protection: After transporting special media, thoroughly clean the inside of the tank to remove residues, and take appropriate methods (such as drying, nitrogen filling, etc.) to prevent moisture retention and corrosion.

Repair and recoating: Once corrosion or coating damage is found, anti-corrosion treatments such as rust removal, repair, and recoating should be carried out in a timely manner.

How to avoid cracking of aluminum plates during the production process of tank truck bodies?

Due to the particularity of transporting goods, tank trucks must avoid problems such as tank cracks. This requires the aluminum plate to have strong resistance to stress cracking. Chinalco’s cold rolling project uses a German Simark six-roller cold rolling mill to eliminate internal stress, prevent deformation during cutting, and effectively avoid cracking problems.

Tank truck aluminum plate price

The price of aluminum plate for tank cars will vary based on several factors, including the alloy type, thickness, size, surface treatment and market supply and demand of the aluminum plate.

Generally speaking, the price of aluminum plates will vary according to the type of alloy. The price of alloys with high strength and better corrosion resistance may be higher.

In addition, the thickness and size of the aluminum plate will also affect the price. Aluminum plates with thicker thickness and larger size will usually be more expensive. Surface treatment will also affect the price, such as anodizing, mirror treatment, painting treatment, etc., which will increase the cost.
