Plastic tanks are safer

The difference between the cost of an oil tank and a plastic tank is not very great. What are the differences between the two?


1. the metal tank weight larger, to some extent, increased the car's fuel consumption, plastic fuel tank weight is generally only 1/2 of the metal tank, thereby reducing the energy consumption of the car.

2. metal fuel tank is generally welding molding, welding seam, vulnerable to rupture, oil leakage, plastic fuel tank one-time blow molding, with better impact resistance, deformation resistance, cracking performance.

3. metal tank, especially the iron tank, long time easy oxidation and rust, plastic tank corrosion resistance, with strong anti external environmental corrosion and oil erosion resistance performance.

4. plastic tanks have greater freedom of styling than metal tanks, and you can choose the right space for the car.

5. plastic fuel tank noise is low, and the reuse rate as high as 90%.

6. the biggest problem is that the metal tank friction or collision when the outside, easy to deformation, sparks, causing burning or explosion, and by the temperature, environmental impact, plastic tank compared to much safer. Plastic fuel tank has just launched, being easy to aging and oil leakage problems, but with the development of material technology, plastic tank now have high resistance to oil, the original oil leakage and aging problem has been improving.


But this does not mean that all cars must use plastic fuel tanks. The biggest drawback of plastic tanks is that they can not be designed too large, otherwise the tank itself can not afford them. As a result, almost all of the large buses and trucks use tin fuel tanks. For them, the weight of the tank does not have much effect on the weight of the car itself.
