45000 liters tri axle fuel tanker trailer material requirements and anti-corrosion treatment

45000 liters tri axle fuel tanker trailer is mainly used for the transportation of various oils and chemical liquids in the petrochemical sector, that is, the transportation of various gasoline, diesel, liquefied petroleum gas, liquefied natural gas and other liquid resins. Because of the particularity of the transported material, the material of the tank body of the chemical truck needs to be determined according to the characteristics of the transported product.

Aluminum plate and aluminum alloy plate. Aluminum plate and aluminum alloy plate are light in weight, good in plasticity, easy to form, and have long service life. They are an ideal tank material. However, tanks made of aluminum plates and aluminum alloy plates have low strength and poor carrying capacity.

Therefore, it is mostly suitable for shipping aviation fuel, concentrated nitric acid, ice nitric acid, anhydrous alcohol, organic solvents and other chemical products and food items. It is not suitable for shipping compressed gas, liquefied gas and easily decomposable gas.

The structure of the 3 Axle Fuel tanker trailer is an elliptical cylindrical or trapezoidal cylindrical body, made of a high-quality steel plate. The whole tank is divided into single or multiple warehouses. The inside of the tank can be divided into compartments. The lower end of the intermediate partition has a through-hole, and the middle of each warehouse is welded with a divided warehouse.

Or multiple warehouses, the warehouse can be divided into chambers, the lower end of the middle partition has a through-hole, and the middle of each warehouse is welded with a partition reinforced wave partition to reduce the impact of the oil in the tank and improve the rigidity of the tank when the car is driving.

In order to prevent corrosion, the surface of the tank is coated with anti-rust paint and decorative paint. The 4 axle fuel tanker trailer is equipped with a container indicator in the middle of the side, which can directly indicate the volume of the tank when refueling or transporting oil to the tank. (Optional) The mouth of the tank is a hole with a diameter of 500mm for maintenance purposes.

The large lid is fastened to the can mouth stiffening plate by bolts, and the small lid and the large lid are connected by a support pin and an ear plate. Turn the handle on the small lid clockwise to press the small lid tightly. Reverse, after removing the ear plate, the small cover can be opened, and a breathing valve is installed on the upper side of the big cover.

In order to ensure that the oil tanker trailer is working, the pressure in the tank is basically the same as the atmospheric pressure, a breathing valve is installed on the large cover of the tank. When the oil in the tank is heated to expand or when the oil pump is used to refuel the tank, the oil surface in the tank. The rising pressure increases.

When the pressure in the tank is higher than the external pressure by 8KPA, the upper valve plate of the breathing valve opens; when the oil is discharged from the oil pump or the oil is cold contracted, the oil level drops and the pressure decreases. When the pressure in the tank is lower than When the external pressure is 3KPA, the lower valve plate of the breathing valve opens. It has the functions of self-priming and self-supplying oil, and can be divided into two to three different specifications of oil, and a double pump is optional.
