1. What is a Fuel Tanker Trailer?

Fuel tanker trailer are mainly used for transport liquid and oil. The tank body is generally made of carbon steel sheet, and it can also be made of aluminum alloy, stainless steel, polyethylene and other materials.

The tank body has sufficient strength. There are anti-shock plates inside the diesel tank trailer. There are manholes and liquid discharge valves in the tank accessories. One of our fuel tanker trailer can transport two kind of oil, it can be divided into tanks. Common tank material is carbon steel Q345, thickness is 4mm-6mm national standard steel plate.

(1) What are the common types of fuel tanker trailer?

Petrol tanker trailer material: carbon steel, stainless steel, aluminum alloy, pure aluminum tank, rubber-lined, rotomolded, plastic tank, glass steel tank can also be used as required

Tanker trailer body types: square, oval, round.

(2) How many the tonnage and volume of the fuel tanker trailer?

Storage tanker trailer transport tonnages are 30 tons, 40 tons, 50 tons, etc. The volume of petrol tanker trailer often purchased are 30 cubic meters, 35 cubic meters, 40 cubic meters, 45 cubic meters, 50 cubic meters, 55 cubic meters, and 60 cubic meters.

(3) What can the petrol tanker trailer transport?

Diesel tank trailer mainly transport gasoline, diesel, crude oil, lubricating oil, olive oil, soybean oil, olive oil, alcohol, edible oil. Stainless steel tanker trailer can also be used to transport chemical products such as sulfuric acid, hydrochloric acid, phosphoric acid and caustic soda. raw material.

2. Package and transportation of oil tank trailer

Fuel tanker trucks trailer for sale usually adopt by bulk carriers or ro-ro ships. We spray wax on the tank. Cover it with a waterproof rain cloth.

Some countries can also ship by container or frame cabinet.

3. What`s the bottom filling of the storage tanker trailer?

(1) Bottom loading system of the storage tanker trailer

In the previous Fuel Tank Semi Trailer, we pour oil into the tank from the manhole above the tank trailer.Add a special oil pump at the rear of the petrol tanker trailer to realize the reverse loading and unloading of diesel.

Now, in order to improve the safety, our fuel tank trailer production has all done the bottom filling process.

What is bottom filling? Important components for bottom filling: The main components of bottom filling are exhaust gas recovery system, anti-spill system, subsea valve, European standard tank mouth, control head, SO2 socket, anti-static system, bottom canned API connector.

(2) European standard aluminum alloy tank cover

Aluminum alloy European standard tank cover is also manhole cover. It`s usually on the top of the oil tank, the tank cover has built-in breathing and emergency exhaust functions. Our diesel trailer has oil and gas recovery valve, oil measuring hole, anti-overflow probe on the manhole cover, etc.

During the filling process of the anti-overflow sensing system, when the liquid level reaches the detection position, the sensing system will automatically alarm to stop the loading of the oil.

The built-in breathing valve keeps the internal pressure of the fuel tank trailer stable and balanced with the external pressure when transporting oil.

Its spill-proof design prevents tanker trucks from being sealed in the event of an accident.

When the pressure of the emergency exhaust device in the fuel tank rises sharply, it will automatically open to release the pressure in the fuel tank, thereby preventing accidents and greatly improving the safety of oil transportation.

(3) Subsea valve

Subsea valve(emergency shut-off valve). Simple operation, time saving, safety and environmental protection.

Pressure-balanced subsea valve is used for multi-compartment tanker trucks, which can carry out separate loading and unloading of different tanks. The three-way design simplifies the pipeline, reduces the load, easy to operate, and safe and reliable.

The pneumatic shut-off valve is installed at the bottom of the tanker tank and can be refueled. The internal pressure of the valve is small, the flow is large, and there is a cut-out groove on the flange of the valve body.If the force is too large, the car body pipeline and the tank body will be automatically disconnected, and the automatic centering plunger and durable spring will still remain sealed, and the medium in the tank will not leak, thereby ensuring the safety of the oil tank.

When we can`t open because there is no air source or other reasons, we can open the cylinder piston rod and open it manually.

4. How to maintain the gas tanker trailer?

In addition to the normal inspection of the braking system and the lubrication system, the gasoline tanker semi-trailer should also pay attention to the following points:

(1) Do not make the tire pressure too high.

If the tire pressure is too high, the ground contact area of the tire will be reduced. The tread wear will be severe, this will reduce the braking effect when braking. There is no doubt that this will affect driving safety; when the air pressure is too high, the tires will easily explode on bumpy roads.

However, too low tire pressure is not good. Too low tire pressure will accelerate tire wear, increase vehicle fuel consumption, and also affect driving safety and vehicle braking effect.

(2) Too much diesel or gasoline filling in diesel tanker trailer. Too much diesel or gasoline can easily block the breathing valve. As a result, steam cannot be effectively eliminated, and pressure is generated inside the tanker truck. Valve damage has occurred.
