Even in the last century, the fuel tank was most often made of steel. In parallel with this, in the 70s. in Europe, containers made of polyethylene began to be widely used, while in the domestic market they have not yet heard of such products. But the advantages of plastic containers were that they can store fuel, fuel and other lubricants. Moreover, the walls of the products were not subject to corrosion, and the tanks themselves served much longer than steel ones, allowing you to save money.
In Russia, such containers appeared only 20 years ago, but during this time they managed to gain popularity among consumers. Already today, tanks made of high-strength polyethylene are known everywhere. This is due to the fact that plastic containers have many advantages that distinguish these containers when compared with analogues. The construction industry over the past 20 years has developed widely and increased in volume, which allowed polyethylene fuel tanks to gain 15% of the market at the beginning of this millennium.
Features of plastic containers
Plastic fuel and lubricants tank today is offered for sale in various shapes and models, thisplays a huge role for the consumer when choosing. These containers are of higher quality. The containers are manufactured using professional equipment, in the process of which the requirements and standards of GOST are observed.
The plastic tank for fuels and lubricants is a one-piece monolithic product, the maximum dimensions of which are 5 m. The possible volume can reach 15,000 liters. Such products allow you to store flammable liquids inside them, such as oil, oil, diesel fuel and diesel fuel. You can use the containers as a container for storing water, as they are as safe and durable as possible.
The only thing to consider when choosing is the size. The container is highly resistant to environmental influences, which is especially true for aggressive manifestations. Thanks to these qualities, containers can be used in any conditions, storing combustible substances, as well as food products.
Cost of plastic containers
If you are looking for horizontal fuel tanks, you can pay attention to some models, the capacity of which is different, as well as the dimensions. If we are talking about a volume of 14,500 liters, then you will have to pay 154,600 rubles for such a capacity. In this case, the diameter and length are 2310 and 3860 mm, respectively. The weight of such a tank is 350 kg.
On sale you can find plastic horizontal containers, the volume of which is 11,800 liters. This cylindrical container has a diameter and length equal to2310 and 3170 mm respectively. Such a tank will weigh 250 kg, and its cost is 105,000 rubles.
Features of steel tanks
The fuel tank can be made of steel. If you want the structure to be protected from corrosion, then it is best to choose a standard wall thickness. But operation in a more aggressive environment involves the use of thicker walls. During the manufacturing process, the tank is prepared from the inside and outside by sandblasting. The most common steel grades that are used during operation are: 09g2s and AISI 304. Such steel is suitable for low-temperature latitudes. If the minimum temperature does not fall below -40 ° C, then the St3sp5 brand will do. But the containers that are used in the food industry are made of AISI 304 steel, these features must be taken into account when choosing.
Characteristics of the steel vertical tank RVS
Fuel storage tanks may be different, but if you choose the steel model, which has a capacity of 100m3, then its inner diameter will be 4790mm. The wall height is 6000 mm. Estimated filling height is equivalent to 5700 mm.
The walls are reinforced with four belts, and the corrosion allowance is 1 mm. The thickness of the upper chord is 5 mm, as is the thickness of the lower chord. The roof of the vertical tank is 4mm thick.
Features of manufacturing steel tanks
Steel tanks for fuel and lubricants canbe made by the roll method, in which the sheets are welded and subsequently rolled onto a coil of a spiral staircase. The bottom and roof elements are welded, which are assembled using a tractor or a truck crane. The advantages of this technology are the possibility of manufacturing in the factory, as well as the absence of the influence of weather conditions on the production time. However, there are also disadvantages, which are expressed in expensive transportation to the destination, as well as in the susceptibility of products to corrosion during storage.
Storage tanks for fuels and lubricants made of steel can also be manufactured using the sheet method; the structures are delivered to the place of installation in the form of separate sheets. The walls of the container are built up with a crane, and can also be raised with a hydraulic jack. Delivery of metal in this case turns out to be cheaper, and the tank itself can be made even underground. Additional advantages of this technology is a shorter period of work compared to roll technology. Weather conditions will affect the duration of the work, and the walls may rust.
Collapsible method of manufacturing steel tanks
Another way to manufacture steel tanks is to use the prefabricated bolt method. Elements are cut to the required dimensions, in which holes are drilled for installing bolts. Elements are sandblasted, degreased and dedusted. At the next stage, enamel is applied to the surface of the walls, which is baked atexposed to a temperature of 400 °C. Coating thickness can reach 400 microns.
Further, the sheets are packed in a container and transported to the installation site. At the site, the tanks are assembled using jacks and using the belt extension method. The sheets are treated with sealants when joining, with regard to the bolted connection. The advantages of this method are the almost complete readiness of the product for the installation process. Among other things, the collection of tanks can be carried out in a limited space. The terms of work are reduced in comparison with sheet and roll technology. However, not every organization is able to carry out the work of such a plan.
Positive Features of Horizontal Steel Tanks
Tanks for storing fuels and lubricants (8, 5 - the dimensions of the walls in millimeters for such containers) are also horizontal. Such designs have many advantages, among them:
- possibility of convenient vehicle access;
- ability to maneuver at the entrance;
- presence of an unloading platform;
- possibility of opening the barrel in a clean room;
- easy delivery of fuels and lubricants;
- simple warehouse inventory.
Such tanks are convenient not only for storing raw materials for a long time, but also for active daily use at gas stations. The tank can be ground, horizontal or underground. The basis of the product can be steelbrand 09G2S or stainless steel. Optionally, you can choose the number of necks, as well as the possibility of installing additional equipment. As protective coatings, varnish, primer or bituminous mastic is used. Inside, the coating can be made of zinc plating, sometimes the protection is applied using the cold galvanizing method. The latest technology from the above allows the material to acquire the qualities of resistance to the aggressive effects of diesel fuel.
Features of soft tanks
On sale you can find soft fuel tanks, they are intended not only for storage, but also for transportation. They are made from heavy-duty polyester fabric, which is made using ballistic weaving technology. On both sides there is a polyurethane or special PVC coating. The shell material guarantees durability, performance of the product at a wide temperature range, as well as tightness. The flexible fuel and lubricant reservoir can also be operated at temperatures from -60 to +80 °C. Tanks of this type have proven themselves even in the most extreme conditions, such as tropical rainforests, harsh tundra and hot deserts.
Conclusion
For some customers, steel tanks are the best solution, while others choose reliable, lightweight and compact flexible fuel tanks, which can be used to organize reliable storage of materials in the factory and field.
The soil maybe absolutely anything, the surface can be sand, snow, stones, beams, ravines and even swampy areas that do not harm the quality of products. At the request of the customer, the manufacturer can produce tanks with a nominal capacity of up to 500 m3. The shell of soft tanks is made of high-strength materials, it is supplied with tie-downs to the transport platform.
