The correct conduct of installation work on deployment requires the simultaneous installation and fixing of the upper dull corner and especially the radial elements of the tank. In this case, the expanded part of the tank immediately acquires stiffness and strength, as in the finished tank. The rafter ceiling is installed with an ordinary car crane, the arrow of which is increased. The crane drives inside the tank for this purpose on the bottom. During polystyle assembly of tanks of the same size, it is impossible to mount the overlap with an autocrane, since the latter cannot go inside the tank, and for the installation through the wall a too long arrow is required.
The first large reservoir built in the new method in 1949. At one of the oil refineries, it turned out to be much better than reservoirs mounted from individual sheets. Tanks made by the folding method are very accurate, which is significant for measuring the number of product stored in the product reservoir. Still premature to summarize the final results on the technical and economic indicators of the application of a new method of constructing tanks. When switching to factory production of tanks, the volume of assembly and welding work performed on the construction site is reduced for large tanks by six times. Of the 2036 m of the seams, which are 5,000 mg attributing to one reservoir, only 285 m with new technology have to be done at the construction site. As a result of this, as the calculations show, the cost of building the tank is approximately halved, not counting the cost of the metal spent. Offectiveness is determined by a higher level of mechanization of work at the factory and the best organization of work. With the factory method of manufacturing tanks, the quality of work is significantly increased.
