Probably no one industry which, in one form or another would not be used tanks.What is RVS, what it is and how it happens?Let's try to understand.
First of all, try to define the reservoir as a common type.Reservoir - a vertical or horizontal container intended for distribution and storage of both liquid and gaseous products.As a material used for the production of steel tank, and even reinforced rubber goods.The most widely used among these materials is obtained steel.
PBC stands for "vertical steel tanks."The scope of this type of tank is rather wide (from the water storage to store various types of petroleum products and oil).It should be noted that the emergence in Russia of vertical tanks are inseparably linked with the name of the outstanding Russian design engineer VGShukhov.It was on his project in 1878, it was built Russia's first vertical steel tank.Initially, vertical tanks not expect a small amount of stored product.However, due to the rapid growth of industrial production and the need for daily use ever-increasing amounts of natural resources (eg, oil) began to place new demands on the volume of the reservoir towards its increase.In addition, the advantage of the larger capacity tanks lay in the fact that, if necessary, to keep the product in a comparable volume of one tank takes up much less space than a somewhat smaller capacity.
Vertical steel tanks can be divided into three types:
- without pontoons (abbreviated - PBC);
- with pontoon (abbreviated - RVSP);
- floating roof (abbreviated - RVSPK).
The choice of the above types of tanks are subject to the classification of products according to the saturated vapor pressure and flash point.
addition, vertical steel tanks further divided by location on the ground and groundwater, as well as the number of cameras (single-chamber and multi-chamber) and the number of the wall (single wall and double wall).
Vertical steel tanks, both in Russia and abroad decided to make two basic methods:
1) a method of sheet assemblage - the bond finished sheets by welding and special equipment is carried out on the construction site;
2) by roll - Deployment Tools finished roll on a construction site.
There was widespread method of rolling of it, becausemost of the work carried out by the manufacturer of tanks, using special equipment that improves the quality and strength of the welds.
tank itself is not ready to use the system.An important aspect of the equipment gets here.By Tank equipment strapping (common term among specialists rezervuarostroeniya) include: electrical equipment (lighting poles, lights, and other electrical appliances appropriate degree of explosion protection), tank equipment (breathing valves of various kinds, ventilation pipes, firecrackers, control mechanisms, flame arrestors, pulleys, hinges, tubing, etc.), structural reservoir device (manholes, pipes, etc.), fire-fighting equipment (foam generators, foam extinguishing nadsloynogo cameras, etc.), metrology equipment (samplers, floating fence device metroshtoki, level), loading devices (siphon valves, two-way dispensers, etc.), installation of erosion sediment.Only the presence of a full range of equipment under the project allows you to use the tank for its intended purpose.
