4 Advice to Choose a Liquefied Gas Semi-Trailer

Tank type semi-trailer refers to a semi-trailer with a tank structure in the cargo box. It is commonly used in transportation operations and is generally widely used in industries, agriculture, commerce, and other fields. It is mainly used for transporting oil, gas, bulk materials, etc. Fuel tank semi-trailers are often used to transport liquid substances such as gasoline, kerosene, diesel, vegetable oil, edible oil, etc. Compared to ordinary integrated tank trucks, they have lower transportation costs and lower fuel consumption under the same load conditions, effectively improving transportation efficiency. The fuel tank semi trailer can be further subdivided according to different aspects, and the specific selection should also be based on personal needs. This article will discuss how to more clearly select fuel tank semi trailer from four aspects: tank material, compartment design, the number of axles, and discharging.

1.Tank material

Carbon steel, aluminum alloy, and stainless steel are commonly used in fuel tank semi-trailers, among which carbon steel tanks are more commonly used. Choosing a suitable tank body can transport goods more safely and efficiently.

Carbon steel tank: Made of high-strength steel with high hardness and good wear resistance, with a high cost performance.

Aluminum alloy tank: Aluminum alloy material itself is relatively light, so under the same load conditions, the weight of aluminum alloy tanks is generally about 4 tons lighter than carbon steel tnaks, which is more suitable for countries with strict weight restrictions, such as Zimbabwe.

Stainless steel tank: Generally, 304 food grade stainless steel materials are used to transport drinking water such as milk, or 316L industrial stainless steel is used to transport corrosive liquids such as sulfuric acid.

2.The number of axles

The number of axles is often designed based on the vehicle's load capacity. The higher the load capacity, the greater the required chassis carrying capacity, and the more axles are required. Moreover, multi axle lifting can also be done on the front axle, and there is no frictional resistance between the tires of the lifting axle and the ground under no-load conditions, which can reduce fuel consumption.

3.Compartment quantity selection

The number of compartments in the fuel tank can be determined according to demand, and one or more compartments can be customized. Multiple compartments can also be used to transport different materials separately, ensuring that multiple materials are transported in one tank without mixing different liquids. And each compartment can be of equal size or different capacity sizes, thereby better improving utilization.

Tank trailers are key equipment for transporting hazardous materials, ensuring the safe delivery of substances such as oil and chemicals. Their role in industry, agriculture and commerce is becoming increasingly important as the global economy and energy demand grows. These trailers incorporate advanced designs and technologies, such as multi-compartment and vapour recovery systems, to effectively reduce the risk of leaks, explosions and corrosion. As a specialist manufacturer, Truckman Auto offers a wide range of tank trailers to meet different transport needs. There is no substitute for a tank trailer in transporting hazardous materials, and each type has its specific purpose. In this article, we will introduce the types of tank trailers, selection points and safety measures in detail to help you improve transport efficiency and safety.

Tank trailer is a special vehicle designed for transporting dangerous goods. It is widely used in industrial, agricultural and commercial fields, mainly undertaking the task of transporting oil, natural gas, chemicals, food liquids and bulk materials to ensure the safe delivery of goods.

This type of trailer adopts a variety of design structures to adapt to different needs. The baffle type has a perforated internal divider to minimise liquid sloshing. The bulkhead divides the tank into separate storage compartments for easy separation of different cargoes. Smooth-bore tanks are smooth and barrier-free, easy to clean and suitable for single-category transport.

The choice of tank material has a direct impact on transport safety. Lightweight aluminium reduces deadweight. Stainless steel offers high corrosion resistance. Carbon steel is known for its high strength and durability. A reasonable combination of different materials can improve transport efficiency and safety.

According to the differences in transport objects, tank trailers are also subdivided into four professional categories: liquid tankers, gas tankers, powder material tankers and bulk cement trailers. Reasonable selection can not only improve the economic efficiency of transport, but also ensure compliance with the strict safety regulations for the transport of dangerous goods.

Small Mobile Tanker: Small Mobile Tanker 1,000-3,000 gallon capacity design, suitable for pickup truck towing. Flexible, suitable for farm irrigation, construction site oil supply and emergency response in disaster areas, etc. It can enter areas that are difficult to reach by large vehicles.

Gas Transport Semi-trailer: Gas transport semi-trailer adopts high-pressure carbon steel tank to transport LPG/LNG and other gas fuels. Equipped with multiple safety valves and pressure control systems, it is commonly used for LPG distribution in residential areas to meet the needs of domestic and industrial/commercial gas consumption.

All types of tanker trucks are designed for specific transport needs, with differentiated features in material selection, safety configuration and functional design, which together form an important part of the modern logistics and transport system.

The design and capacity of a tank trailer directly determine the safety and efficiency of dangerous goods transport. Below are the key features to ensure efficient and stable cargo transport.

Baffle Design: Reduces liquid shaking and improves driving stability through perforated bulkheads. Commonly used in fuel and chemical trailers to prevent liquid surge during transport.

Bulkhead design: Separates the tank into multiple storage compartments to avoid cargo mixing. Ideal for food-grade and crude oil trailers where multiple liquids can be transported at the same time.

Smooth-bore design: Smooth interior without dividers for easy cleaning and sterilisation. Suitable for single bulk materials such as powdered cement, ensuring smooth unloading.

Stainless steel material: corrosion-resistant and conforms to food hygiene standards, prolonging service life. Widely used in food and chemical trailers to ensure cargo purity.

Aluminium: Lightweight design improves load efficiency and fuel economy. Commonly used in fuel trailers to reduce transport costs.

Carbon Steel: Tough and pressure resistant, withstands high temperature and pressure conditions. Suitable for gas and asphalt trailers to ensure structural strength.

Small Capacity Range: 1,000 to 3,000 gallon capacity for short-distance local distribution. Commonly used in mobile trailers for flexible service to job sites or disaster areas.

Large Capacity Range: Capacities of 5,000 to 11,600 gallons for long-haul needs. Used in fuel and chemical trailers to support bulk transport.

Dry Bulk Capacity Range: Capacities from 560 to 3,120 cubic feet designed for bulk materials. For powdered cement trailers to ensure efficient loading and unloading.

Choosing the right tank trailer requires a number of factors to be considered, both to ensure safe transport and to achieve economic efficiency. Here are the key points to help you make the best choice for your needs and budget:

Cargo: Defining the type of cargo to be transported is the first step. Food-grade trailers are suitable for milk, fruit juices, etc. Chemical trailers are suitable for nitric acid, ethanol and so on. Fuel trailers are for petrol and diesel. Choosing the right trailer can effectively prevent pollution and safety hazards.

Capacity: The capacity of a tank trailer determines transport capacity and cost. Capacity ranges from 1,000 gallons to 11,600 gallons, and price increases with load capacity. Choosing the right model for your volume and budget ensures efficient operation.

Distance: Distance is also an important consideration. Short distance deliveries (e.g., local job sites) can be made with a small trailer. Long-distance transport (e.g. cross-city fuel) requires a large-capacity trailer. When transporting long distances, efficiency and durability are important considerations.

Safety equipment: Dangerous goods transport requires that trailers are well equipped with safety systems. Submarine, emergency shut-off and overflow valves prevent leaks; pressure relief valves are used to manage pressure; and fire extinguishers respond to fires. Ensuring that the trailer meets DOT standards enhances overall safety.

Industry Suitability: Different industries have different needs for trailers. Agriculture typically chooses water tanks or small trailers; the construction industry requires powdered cement or asphalt trailers; and the energy industry relies on fuel and gas trailers. Choosing the more appropriate equipment for the industry helps to optimise transport efficiency.

Regulatory Requirements: Regulatory compliance is critical. Food trailers need to meet FDA sanitation standards, and chemical and fuel trailers should follow DOT-406 or 407 specifications. Also, make sure the trailer and driver are legally qualified (e.g., CDL) to avoid penalties.

Tank trailer maintenance and safety measures are directly related to the reliability and safety of hazardous materials transport. The following are key points to ensure trailer performance and compliance.

Tank cleaning: Clean the inside of the tank once a month to remove dirt and debris. Food-grade trailers need to be thoroughly sanitised and chemical trailers need to be rinsed of residue to prolong service life and ensure cargo quality.

Regular inspections: Check valves, hoses and sumps every three weeks to confirm no leaks or wear. Annual comprehensive testing, including brake systems and safety equipment, ensures compliance with DOT standards.

Safety equipment maintenance: test subsea valves, emergency shut-off valves and pressure relief valves monthly to ensure proper function. Check fire extinguishers for expiration dates and keep them readily available to address fire risks.

Work area safety: No matches, lighters or open flames are allowed in the work area. Electrical equipment needs explosion-proof certification to avoid accidents caused by static electricity or sparks.

Standardise the use of tools: use copper or alloy spanners when overhauling to avoid sparks caused by knocking iron tools. Ensure safe operation and reduce the risk of explosion.

Driver training: Drivers need to receive dangerous goods transport training, updated annually, to master the loading and unloading process and emergency handling. Hold CDL certification to ensure compliant operation.
