Problems solved by technology

[0021] ②However, the plate width of 2440mm is not the ideal plate width for domestic mainstream wide and thick plate manufacturers
As one of the prefabrication processes of traditional storage tank wall panels, the crimping of wall panels not only increases the manufacturing cost of storage tanks, but also prolongs the manufacturing cycle

Embodiment 1

[0063] In this embodiment, a petroleum tank wall structure with a theoretical capacity of 100,000 cubic meters and steel plates for the tank wall are designed.

[0064] In the existing traditional design, the tank wall structure of such an oil storage tank with a design capacity of 100,000 cubic meters should be as follows: Figure 6 shown. In the figure, 2 is a schematic diagram of the steel plate for the tank wall, and 21, 22, 23, 24, 25, 26, 27, 28 and 29 are the first layer, the second layer, and the third layer of the tank wall from top to bottom. , 4th, 5th, 6th, 7th, 8th, and 9th-layer steel plate thickness profiles. The wall of this traditional 100,000 cubic meter oil storage tank is circular, with a circumference of 252 meters, a tank wall height of 21.96 meters, and a limit oil level of 20.5 meters; A 2440mm wide × 12600mm long steel plate is welded with the plate width as the height and the plate length as the arc length. From top to bottom, the first and second ...

Embodiment 2

[0088] In this embodiment, a petroleum storage tank wall structure and steel plates for the tank wall with a theoretical capacity of 150,000 cubic meters are designed.

[0089] In the existing traditional design, the tank wall structure of such an oil storage tank with a design capacity of 150,000 cubic meters should be as follows: Figure 7 shown. In the figure, 2 is a schematic diagram of the plate surface of the steel plate used for the tank wall. The tank wall is divided into 7 layers. Schematic diagram of the thickness profile of the 3rd, 4th, 5th, 6th and 7th layer steel plates. The wall of this traditional 150,000 cubic meter oil storage tank is circular, with a circumference of 315 meters, a tank wall height of 20 meters, and a limit oil level of 19 meters; the first to sixth floors from top to bottom are 2800mm high, and the The height of the 7 floors (that is, the bottom layer) is 3200mm, and each layer is welded by 25 steel plates with a length of 12600mm, with th...

Abstract

The invention relates to a TMCP high strength steel plate for a large storage tank wall and a production method of the steel plate as well as a tank wall structure. In the length direction, one end of the steel plate is thick and the other end is thin, and the plate thickness is linearly increasing or decreasingin the overall or partial length section; the width and length of the steel plate are constant, the thickness of the steel plate changes along with the change in the length direction, and the ratio of the plate thickness Tb at the thickest end to the plate thickness Ta at the thinnest end is not greater than 3; L1, L2... are respectively different distances away from the thin end part of the steel plate, and in the distances, the thicknesses of the steel plate are respectively T1, T2..., the rest can be deduced by analogy; and the plate thickness in the length interval scopes of 0-L1, L1-L2... islinearly increasing or decreasing, and the slope of increase or decrease of the thickness in the length interval is constant. According to the invention, on the premise of not affecting the capacity and safety of the storage tank, material use amount of the steel plate for the tank wall can be remarkably reduced, the prefabricating machining procedure of the wall plate can be reduced, and the welding construction efficiency of the tank wall can be improved; and the steel plate for the tank wall has the characteristics of being large in width and having thickness in trapezoid gradual change, thus being applicable to large storage tanks with a capacity of 100-150 thousand cubic meters.

Description

technical field [0001] The invention relates to a TMCP high-strength steel plate for the tank wall of a large storage tank, a manufacturing method thereof and a tank wall structure. Background technique [0002] The construction of oil storage tanks can play an extremely important role in ensuring national energy security and responding to the shortage of refined oil supply. The large-scale construction of large-scale oil storage tanks in my country began in 2005. The first four national strategic oil reserve bases were put into use in 2008. A total of 164 oil storage tanks of 100,000 cubic meters were built, with a total reserve of 16.4 million cubic meters. , or about 14 million tons. In 2011, the second phase of the project involving 8 oil reserve bases and more than 200 large oil storage tanks of 100,000 to 150,000 cubic meters started construction. According to the plan, my country's crude oil national storage and commercial storage projects will also start construction...
