Back in the last century, a reservoir for fuel and lubricants 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 had not heard of such products. But the advantages of plastic containers was that they can store fuel, fuel and other lubricants. Moreover, the walls of the products were not susceptible to corrosion, and the tanks themselves served much longer than steel, allowing saving.
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 these containers emit when compared with analogues. The construction industry over the past 20 years has developed widely and increased in volume, which allowed at the beginning of this millennium polyethylene fuel tanks to gain 15% of the market.
Features of plastic containers
A reservoir for fuel and lubricants made of plastic today is offered for sale in various forms and models, this plays a huge role for the consumer when choosing. Such containers are of higher quality. Capacities are manufactured using professional equipment, in the process of which the requirements and standards of GOST are observed.
The plastic reservoir for fuels and lubricants is an integral 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 yourself like oil, oil, diesel fuel and diesel fuel. You can use containers as containers for storing water, as they are as safe and durable as possible.
The only caveat to consider when choosing is size. The tank 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 in them.
The cost of plastic containers
If you are looking for horizontal tanks for fuels and lubricants, you can pay attention to some models whose capacities differ, as well as their sizes. If we are talking about the volume of 14,500 liters, then you will have to pay 154,600 rubles for such a capacity. Furthermore, 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 a length of 2310 and 3170 mm, respectively. Such a tank will weigh 250 kg, and its cost is 105,000 rubles.
Features of steel tanks
The tank for fuel and lubricants can be made of steel. If you want the structure to be protected from corrosion, it is best to choose a standard wall thickness. But operation in a more aggressive environment involves the use of thicker walls. In the manufacturing process, the tank is prepared internally and externally 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 is suitable. But the containers that are operated 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
Storage tanks for fuels and lubricants can be different, but if you choose a steel model with a capacity of 100 m 3 , then its internal diameter will be 4790 mm. The height of the wall is 6000 mm. The estimated filling height is equivalent to 5700 mm.
The walls are reinforced with four belts, and the allowance for corrosion is 1 mm. The thickness of the upper belt is 5 mm, as is the thickness of the lower belt. The roof of the vertical tank is 4 mm thick.
Features of the manufacture of steel tanks
Steel tanks for fuels and lubricants can be manufactured by the roll method, in which the sheets are welded and subsequently folded onto a coil of a spiral staircase. Welding of the bottom and roof elements takes place, which are collected using a tractor or truck crane. The advantages of this technology are the ability to manufacture in the factory, as well as the lack of influence of weather conditions on the production time. However, there are also disadvantages that are expressed in costly transportation to the destination, as well as in the susceptibility of the products to corrosion during storage.
Storage tanks for fuels and lubricants and steel oils can also be manufactured according to the sheet method; they are delivered as separate sheets to the installation site. The walls of the tank are built up using a crane, and can also be tucked up with a hydraulic jack. Metal delivery in this case is 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 become rusty.
Collapsible steel fabrication method
Another method of manufacturing steel tanks is to use the bolted assembly method. Elements are cut to the required dimensions, in which holes are drilled for installing bolts. Elements are sandblasted, degreased and dust free. At the next stage, enamel is applied to the surface of the walls, which is baked when exposed to a temperature of 400 ° C. The coating thickness can reach 400 microns.
Next, the sheets are packed in a container and transported to the installation site. At the site, tanks are assembled using jacks and the use of the belt extension method. Sheets are treated with sealants when joining, as for 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 characteristics of horizontal steel tanks
Storage tanks for fuels and lubricants (8, 5 - wall sizes in millimeters for such tanks) are horizontal. Such designs have many advantages, among them:
- the possibility of convenient access of vehicles;
- the possibility of maneuvering at the entrance;
- the presence of an unloading site;
- the ability to open barrels in a clean room;
- ease of delivery of fuels and lubricants;
- ease of inventory.
Such tanks are convenient not only for storing raw materials for a long time, but also for active daily operation at gas stations. The capacity may be above ground, horizontal or underground. The product may be based on steel grade 09G2S or stainless steel. Optionally, you can choose the number of necks, as well as the ability to install additional equipment. As protective coatings, varnish, primer or bitumen mastic is used. Inside, the coating can be made of zinc metallization, sometimes protection is applied by the method of cold galvanizing. The latest technology from the above allows the material to acquire the qualities of resistance to the aggressive effects of diesel fuel.
Soft Tank Characteristics
On sale you can find soft fuel tanks, they are intended not only for storage, but also for transportation. They are made of heavy-duty polyester fabric, which is made using ballistic weaving technology. On both sides there is a polyurethane or special polyvinyl chloride coating. The material of the shell guarantees the strength, performance of the product over a wide range of temperatures, as well as tightness. The elastic reservoir of fuels and lubricants can be operated at temperatures from -60 to +80 ° C. Tanks of this type have proven themselves even in the most extreme conditions, including tropical rain forests, harsh tundra and hot deserts.
Conclusion
For some consumers, steel tanks are the best solution, while others choose reliable, lightweight and compact elastic fuel tanks, with which you can organize reliable storage of materials in the factory and field conditions.
In this case, the soil can be absolutely anything, the surface may be sand, snow, stones, beams, ravines and even marshy areas that do not harm the quality of the products. At the request of the customer, the manufacturer can manufacture tanks with a nominal capacity of up to 500 m 3 . The shell of soft tanks is made of materials of increased strength, it is provided with tie-down fastenings to the transport platform.
