diesel storage tank

The construction of the diesel storage tank is a systematic project. It is necessary to handle the whole process and control it in all directions. The largest storage tank in the world is a 20×104m3 floating roof tank built in Saudi Arabia. To meet the demand for strategic oil storage, domestic petroleum and petrochemical professionals are planning and creating diesel storage tanks. China has been planning to develop a 15×104m3 floating roof tank on the basis of the planned construction of a 10×104m3 floating roof storage tank. The construction quality of the diesel storage tank project largely determines the application of the tank and its service life, which is directly related to the economic and social benefits of the construction enterprise.

Data prefabrication

For diesel storage tanks, depending on the geographical location of the general site prefabricated, mechanical methods (shearing machine) can be used for cutting, semi-active cutting, CNC cutting, etc. can also be used for flame cutting processing. Hanging plate, placement and transportation: Due to the long plate, the length of the tank wall of 10×104m3 reaches 13000mm, and the length of the middle plate is nearly 15000mm. Therefore, the balance frame for lifting is placed in the whole process of construction, and the balance beam for lifting is erected. To prevent plastic deformation of the plate during the lifting process. From the floor to the wall to the goods to the device, the general demand for several months, during this period due to improper placement of the device may have been formed by plastic deformation, so the board is necessary to level up the accumulation, the thick plate between the wood, Interval control is about 2m. Thin sheets of 3 to 5 sheets are stacked, with wood added between them, and the wood between the layers is in the same orientation. Because the compressive stress due to the onset of its own weight is not completely released when the device is released, it is not suitable for the accumulation of excessive stress. Cutting: If you choose CNC cutting boot, cutting accuracy and groove quality will be stable. If it is a semi-active cutting, each person, each cut and cut out may not be the same, to add a certain degree of difficulty to the assembly welding, in principle, special drawing line, someone cut. The rolled steel plate is placed on the gripper. Try to use stand-up tires to prevent changes in the radian caused by self-weight. Rounding: There is a certain degree of difficulty in manipulating the deformation during the construction process, and it can only rely on the mutual cooperation between the work types and the responsibility of the operators. If the manufacturing of the tyres can be used to prevent the deformation of the plates caused by the poor cooperation between the heaven crane and the rolling board, it will bring many difficulties to the normal construction of the site. First, the tyres are too long and may occupy a large position. The second is to influence the construction of "head pressure". Heat Treatment: The top panel of the diesel storage tank is welded and stress relieved. The detachable heat treatment assembly furnace developed by Sijian Company can meet the field practice requirements. To prevent the onset of cracking at the open hole, the methods and methods for strengthening the welding and heat treatment should be appropriate. If the handling is not good, it is difficult to correct once the seizure is deformed.
