The transportation medium of the tanker is mainly oil, which materials are usually used for the tank body? How should users choose its tank material? Shanghai Trailer will take you to see:
The commonly used tank materials for tank trucks are carbon steel, 304 stainless steel and aluminum alloy. Among them, carbon steel is the most conventional and has the lowest cost. Most oil tankers in African countries use carbon steel tanks; 304 stainless steel is much more expensive than ordinary carbon steel, so few customers use it, but the advantage is that when the tank body is scrapped, the residual value is higher than that of carbon steel; aluminum alloy oil tanks are in the market used more. Why? What are its advantages?
Aluminum alloy tanker is safer:
The aluminum alloy fuel tanker is more than 4.9 tons lighter than the similar carbon steel tanker. The lighter upper tank lowers the center of gravity of the whole vehicle and makes the vehicle run more smoothly; the light weight reduces tire wear and the probability of tire blowout is greatly reduced; aluminum alloy The material has good electrical conductivity, static electricity is not easy to accumulate, and there will be no instantaneous discharge; when the vehicle collides or overturns, it may be necessary to drill holes for oil, and the aluminum alloy will not generate sparks when drilling, eliminating potential safety hazards.
Aluminum alloy tanks are more durable:
Aluminum alloy can form a dense aluminum oxide protective film on the surface, which can effectively prevent atmospheric and moisture erosion, so it has strong anti-oxidation ability, will not rust, and ensure that the transported oil is not polluted. Aluminum alloy tankers are more durable than carbon steel, with a service life of 15-20 years. Because aluminum alloy tankers will not corrode, their appearance is smooth and beautiful, which can enhance the corporate image.
Aluminum alloy fuel tanker is more environmentally friendly:
Aluminum alloy can be recycled. The recycled aluminum alloy material has no difference in performance with the original aluminum alloy material, and can be used repeatedly to reduce resource waste and energy loss; aluminum alloy fuel tanker has light weight and increased payload, which can reduce The number of transportations saves fuel and can reduce various exhaust emissions; the aluminum alloy can withstand the erosion of the atmosphere and moisture, the surface does not need paint, and the air pollution caused by the carbon steel maintenance paint in the production and spraying process is less.
Carbon steel tank trailer:
Carbon steel contains 0.03-2% carbon. Many customers mistakenly think that it is iron, but it is not true. Carbon steel is hard, tough, elastic, and can be cast and malleable, while iron is hard and brittle, and can be cast but not malleable. Carbon steel and iron of the same volume are lighter in weight. . There is no obvious difference between the two on the surface. Because of this, some refit manufacturers will replace carbon steel with iron in order to reduce costs. This is one of the reasons why the prices of different manufacturers are different.
Stainless steel tank trailer:
The stainless steel materials used in shanghai trailers are generally divided into 201 and 304. These two types cannot be distinguished with the naked eye, so users who choose this material must consult clearly before purchasing a car, and even request to indicate it on the contract if necessary. . Type 304 is more resistant to corrosion and high temperature, so it is higher in price than Type 201, but it is worth the money.
Finally, let's talk about the most popular profile in the current tanker market - 5083 magnesium aluminum alloy. It should be noted that not all trailer factories will use this profile. There are also many models of aluminum alloys, and the needs of different fields are different. The 5083 magnesium-aluminum alloy is generally used for welding parts of ships, ships, automobiles, aircraft plates, pressure vessels that require strict fire protection, and missile components. It has high hardness, strong corrosion resistance and good weldability. Most notably, it is very lightweight and at the same time more expensive.
At present, the materials used for oil tankers are mainly carbon steel and aluminum alloys. For oil tankers under 10 tons, carbon steel materials can be selected, because vehicles of this volume are generally used for mobile refueling and do not require high speed. There is no need to consider the problem of overweight; and more than 10 tons, especially the front four and eight rear tankers, usually choose the best aluminum alloy material, its dead weight will be 2.5 tons less than when using carbon steel tanks, of course, in terms of cost. will increase a lot of costs. After talking about the advantages of aluminum alloys, we have to mention its disadvantages. Customers who choose aluminum alloy tanks may also understand that the hardness of aluminum alloy tanks cannot reach the hardness of carbon steel tanks. It is also quite high, so remind customers that this is also a factor to consider when choosing.
However, stainless steel is generally not recommended for customers to choose on tank trucks. Why? First, there is no difference in weight between stainless steel and carbon steel for tanks of the same volume, but the price is the same as that of aluminum alloy tanks, so why not choose aluminum alloy tanks? At the same price, the aluminum alloy tank body is lighter in weight. Therefore, unless the material of stainless steel is specified by the customer, or the material being pulled must be made of this material, we will use it.
