Flammable and explosive? Which is safer, metal fuel tank or plastic fuel tank? The old driver told you.

There are two kinds of fuel tanks in the automobile market now, metal fuel tanks and plastic fuel tanks. Most models on the market are using plastic fuel tanks, which are not high-end and have a strange shape, and the quality of metal fuel tanks seems to be not good enough. So many people have a question, why not use a metal fuel tank? There are also some rumors that metal fuel tanks are flammable and explosive. Is this happening? Is the fuel tank material really important?

Many people think that plastic mailboxes are not strong enough, but this is actually a misunderstanding. Because the plastic fuel tank is made of high-grade plastic instead of ordinary plastic, the biggest feature of this material is its strong plasticity, which can be made into different shapes when it is designed, and it also has strong impact resistance if the vehicle is hit. The friction of plastic itself will not produce flame, so the safety factor of using plastic as fuel tank is very high.

The plastic oil tank has strong corrosion resistance and will not produce impurities due to corrosion. This feature can ensure the cleanliness of the oil supply pipeline and reduce the risk of impurities entering the oil filter or engine. Even if the fuel tank is on fire, the special properties of plastic will form a closed space after melting to avoid the accident from expanding. These advantages of plastic fuel tank, coupled with low manufacturing cost, make it a standard for most models.

Is the metal fuel tank necessarily unsafe? Not exactly. The common metal oil tank-iron oil tank has its disadvantages, such as it may break when hit, low corrosion resistance and easy oil leakage. However, the advantages of iron fuel tank can not be ignored. It is heated evenly and will not penetrate the evaporated gas itself, which is beneficial to thermal expansion. The iron oil tank has good sealing performance.

In addition, in today's environmental protection, compared with the chemical pollution and irrecoverable characteristics of plastic oil tanks in production, metal oil tanks are less polluted. At the same time, the recyclable characteristics of metal fuel tanks also make them advocated and loved by environmentalists. Of course, both have their own shortcomings. Plastic oil tanks need heat insulation nets to block the outside temperature, while metal oil tanks are poor in plasticity and easy to deform.

In the final analysis, whether it is a metal fuel tank or a plastic fuel tank, as long as it is not a fake and shoddy product, meets the national standards and passes the safety test, it can be used with confidence. As rational consumers, we should not be superstitious about rumors. No matter what kind of fuel tank, regular inspection is safe and reliable. Have you learned?
