Specific methods and precautions for replacing double-layer oil tanks in skid-mounted gas stations

During the operation of the skid-mounted gas station, if there is a problem with the double-layer oil tank of the storage tank, we need to replace it immediately. When replacing, we must focus on safety and try not to change the position and parameters of other components. Today, we will explain to you the specific methods and precautions for replacing the double-layer oil tank in the skid-mounted gas station.

The first is the correct method to replace the double-layer oil tank.

In the normal operation of the skid-mounted gas station, it is sometimes inevitable to replace parts. Among the many parts, the double-layer oil tank, as the core component of the skid-mounted gas station, is the best choice. Therefore, how to replace this core component has become an important step in maintaining the skid-mounted gas station. The following is an explanation of the basic method of correctly replacing the double-layer oil tank of the skid-mounted gas station.

The first thing to do is the most basic preparation work, and the most important thing is safety protection work. Whether there is a workplace with fire-fighting equipment is mainly to prevent the sparks of demolition and the remaining objects in the tank from burning, and then pay attention to whether the equipment on site is formed, whether there is a supervisor, can ensure the safety of the construction site.

Secondly, it is the cleaning and dismantling of the oil tank. The equipment needs: explosion-proof fan, foam and fire detector. The explosion-proof fan is for the ventilation of the oil tank, and the gas can be generated at any time to ensure safe blasting. Then the residual foam is cleaned, and the valve is cleared and the cover is opened for disassembly during cleaning. The ignition detector used in the disassembly process detects the oil and gas concentration, and the concentration in the oil tank is concentrated to ensure the safety of the blasting. The body is dismantled. In order to remove the bottom and wall of the tank, the reinforcement ring can be installed, the lifting lug is welded, the tank body hoist is configured, and then the pull hoist is hung.

After that, the tank wall and the bottom plate can be disassembled and cut, and the tank wall and the tank bottom plate can be separated. In the process, the ring of the tank wall is cut off, and the lifting tank is lowered down, and a circle is cut on the tank wall until all the tank walls are cut. It is to cut the railings and accessories on the top, and cut the bottom plate according to the welding sequence.

Finally, the new double-layer oil tank is installed. The specific measures for installing the new double-layer oil tank are similar to the installation method when installing the entire skid-mounted gas station. The most critical thing is that if some small accessories are aged for a long time during installation, they must be replaced with new ones. Remember to lose the big because of the small. The above is the basic method of replacing the double-layer oil tank of the skid-mounted gas station.

I hope it will be helpful to everyone. The daily maintenance of the skid-mounted gas station must be carried out on time. As the saying goes, a thousand-mile dam collapses because of an ant hole. We must eliminate safety hazards in the bud. The above information is provided by the Technical Department of Tai'an Shengding Metal Container Manufacturing Co., Ltd.

The second is the precautions for replacement.

We all know that the most important components of a skid-mounted gas station are double-layer oil tanks and gas dispensers. As the name suggests, double-layer oil tanks are facilities for storing oil products. Gas dispensers are machines that serve us to calculate the amount of fuel. Generally, gas dispensers are directly facing customers, and the oil tanks are inside. The oil pipes used between the two are connected. So what is the safe distance between them? Let's explain it to you below.

The national standard stipulates that the safety distance standard between the skid-mounted gas station and the outside of the station is the distance from the edge of the gas station tank, exhaust pipe and gas dispenser to the door and window openings of the building outside the station. For gas stations of different levels, the higher the level, the greater the distance. For gas stations equipped with oil and gas recovery systems, the safety distance between it and the buildings outside is relatively reduced. Buried tanks can reduce accidental damage and environmental impact. As long as measures are taken on the pipes connected to the ground, they have good fire resistance. The disadvantage is that the cost is high and maintenance is inconvenient, so the specified service life is short. Many roadside gas stations use buried tanks.

Nowadays, newly built gas stations all use double-layer anti-leakage buried oil tanks. Compared with the previous oil storage tanks, this new type of oil storage tank has anti-corrosion, long service life and secondary anti-seepage functions. Moreover, each oil storage tank is equipped with a liquid level gauge with high and low liquid level alarm functions, which provides double protection for the oil storage tanks of gas stations. Furthermore, the oil tanks of gas stations are stored in normal pressure equipment. The atmospheric pressure in the oil tanks and the atmospheric pressure in the air are equal, and there will be no large positive and negative pressure in the oil tanks. Therefore, we don¡¯t have to worry about the oil in the oil tanks penetrating into the soil.

The underground oil storage tanks of skid-mounted gas stations are to bury the storage tanks underground, leaving only the inlet and outlet pipes to the ground and operate on the ground. Everyone thinks that this kind of oil tank is buried underground, so does it mean that there is no defined range between it and the area where we live? In fact, no matter what form the oil tank is built in, in order to ensure personal safety, a safe distance should be set according to certain standards. Regarding this aspect, let's take a look at the following instructions!

The above is the national requirement for the safe distance between the double-layer oil tank and the gas pump in the skid-mounted gas station. This is mainly to ensure that if there is a safety hazard in the gas pump facing the customer, the double-layer oil tank will not be affected as much as possible, thus improving the safety performance.

I hope the above explanation can be of some help to everyone when replacing double-layer oil tanks in the future.
