Introduction to the six detailed processes of container-mounted gas station conversion

With the rise of skid-mounted gas stations, many industries are gradually infiltrating this model, among which container conversion is the most common. This is mainly due to the fact that containers and skid-mounted gas stations have many similarities in appearance, but they are only similar in that the equipment and facilities that need to be installed inside are indispensable. Below we will introduce the six detailed processes of container-mounted gas station conversion.

(1) Skid-mounted gas station tank body The tank body is mainly round and square. Round tanks have the advantages of good strength and easy production; square tanks have the advantage of large volume and are more suitable for gas stations. The tank body is mainly composed of a shell, a manhole, an internal ladder and reinforcement ribs inside the tank. The oil tank shell not only needs to have a certain strength, but also needs to have strong leak-proof performance to prevent oil leakage from polluting the environment. To this end, the shell can be designed as a double-layer: the inner shell is used to store oil; the outer shell protects the inner shell from impact on the one hand, and prevents oil leakage on the other hand. The inner shell is made of materials such as Q345 or 16MnR to ensure the strength of the inner shell; the outer shell mainly plays a protective role, and the material grade can be appropriately reduced, generally using Q235. Manholes and internal ladders allow personnel to enter the tank for inspection and cleaning. Container-type movable refueling tanks are usually prohibited from lifting and transporting operations when loaded with oil. Therefore, under the premise of ensuring strength, buffer plates are generally not installed in the tank. In order to meet the needs of storing different oils at the same time, the oil tank can be divided into multiple independent oil storage tanks, so that the oil tank has the function of one tank for multiple uses.

(2) Pipeline system of skid-mounted gas station The pipeline system consists of an oil filling pipe, an oil suction pipe, an oil return pipe, a sewage pipe, etc. The oil filling pipe is used to fill oil into the tank. Its components include a float valve, a filter, a one-way valve, a ball valve, a quick connector and a steel pipe. The float valve can automatically cut off the oil supply when the oil is filled to the safe height in the tank; the filter is used to prevent impurities in the oil from entering the tank; the one-way valve has the function of preventing the oil in the tank from flowing back and preventing theft; the ball valve acts as a master switch and is only opened when refueling; the quick connector can be connected to the pipeline of the external tank truck. The oil suction pipe is used to refuel the construction machinery, and is mainly composed of the oil suction pipe, filter device, anti-theft valve, ball valve, flow meter, oil suction pump, refueling gun, etc. The drain pipe is used to regularly clean the residue in the tank to keep the oil clean.

(3) Alarm control system of skid-mounted gas station The alarm control system is used to monitor the oil level height in the tank and the process of filling and sucking oil. When the oil level in the tank is lower than the minimum oil level or higher than the maximum safe oil level, the alarm control system will sound an alarm.

(4) Exhaust device of skid-mounted gas station The exhaust device is mainly used to balance the air pressure inside and outside the tank to prevent the tank body from being damaged by excessive pressure or negative pressure in the tank. The exhaust device is divided into a normal pressure exhaust device and an emergency exhaust device: the normal pressure exhaust device is used for exhaust under normal working conditions; the emergency exhaust device is used for emergency exhaust in the event of failure of normal pressure exhaust, which plays a double insurance role. The inner tank and outer tank interlayer of the double-shell oil tank also need to be installed with an exhaust device to balance the pressure in the interlayer.

(5) Leak detection device The leak detection device is used to regularly detect whether the inner tank body is leaking oil. The usual practice is to pass a steel pipe from the top of the oil tank to the bottom of the inner and outer tank interlayer, and then insert a long rod into the steel pipe. If there is an oil stain at the bottom of the long rod, it indicates that the inner tank body is leaking oil.

(6) Lifting and transportation device The lifting and transportation device mainly refers to the container corner fittings and the frame structure that connects the corner fittings to the skid-mounted gas station oil tank into an integral whole. Container-type mobile fuel tanks can only be transported empty, so the requirements for the strength of the frame structure are not as high as those for tank trucks and tank boxes that are specially used to transport oil. Since container-type mobile fuel tanks may need to be transported to the destination by sea or other means of transportation, in order to facilitate transportation, their external dimensions need to meet the design specifications of the container.

The above six detailed processes are the specific operations of converting containers into skid-mounted gas stations. During the conversion process, we must conduct acceptance operations in accordance with the specifications and standards of skid-mounted gas stations. After all, the safety performance of gas stations is not a joke.
