Embodiment 1

[0051] In this embodiment, a petroleum storage tank wall structure and steel plates for the tank wall with a theoretical capacity of 70,000 cubic meters are designed.

[0052] In the existing traditional design, the wall structure of such an oil storage tank with a design capacity of 70,000 cubic meters should be as follows: Figure 4 shown. In the figure, 2 is a schematic diagram of the steel plate for the tank wall, and 21, 22, 23, 24 and 25 are the first, second, third, fourth and fifth layers of the tank wall from top to bottom. Schematic diagram of the thickness profile of the steel plate. The wall of this traditional 70,000 cubic meter oil storage tank is circular, with a circumference of 248 meters, a tank wall height of 15.25 meters, and a limit oil level of 14.5 meters; the tank wall is divided into 5 layers, each layer is 3050 mm high, and the A 3050mm wide × 15250mm long steel plate is welded with the plate width as the height and the plate length as the arc lengt...

Embodiment 2

[0074] In this embodiment, a caustic soda storage tank wall structure with a theoretical capacity of 20,000 cubic meters and the base plate in the carbon steel-stainless steel composite plate used for the tank wall are designed.

[0075] In the existing traditional design, the wall structure of such a caustic soda storage tank with a design capacity of 20,000 cubic meters should be as follows: Figure 5 shown. In the figure, 2 is the plate surface of the steel plate for the tank wall, and 21, 22, 23, 24, 25, 26, 27, 28, 29 and 20 are respectively the first layer, the second layer, and the third layer of the tank wall from top to bottom. Layer, 4th, 5th, 6th, 7th, 8th, 9th and 10th layer steel plate thickness profiles, 3 is the longitudinal weld between the tank wall steel plates, 4 is the tank wall Circumferential welds in the horizontal direction between steel plates. The traditional 20,000 cubic meters caustic soda storage tank has a circular wall with a diameter of 42m, a...

Abstract

A steel plate for the tank wall of a large and medium-sized storage tank, a manufacturing method thereof, and a tank wall structure, wherein the steel plate for the tank wall is thick at one end and thin at the other end in the length direction, and the thickness of the steel plate gradually increases in all or part of the length section or decrease; among them, the plate width W of the steel plate and the plate length L of the steel plate are constant; the thickness of the steel plate changes along the length direction; the ratio of the plate thickness Tb at the thickest end to the plate thickness Ta at the thinnest end is not greater than 4 ; L1, L2... are different distances away from the thin end of the steel plate. At this distance, the thickness of the steel plate is T1, T2..., and the rest are analogous; the plate thickness within the length range of 0~L1, L1~L2... It increases or decreases linearly, and the slope of the thickness increase or decrease within the length interval is constant. The present invention significantly reduces the material usage of tank wall steel plates without affecting the capacity and safety of the storage tank, reduces the prefabrication process of the wall plate, improves the welding construction efficiency of the tank wall, and is suitable for the capacity of 70,000 and below 70,000 Cubic meters of large and medium storage tanks.

Description

technical field [0001] The invention relates to storage tank technology, in particular to a steel plate for a large and medium-sized storage tank wall, a manufacturing method thereof and a tank wall structure, which are suitable for large and medium-sized storage tanks with a capacity of 70,000 cubic meters or less. Background technique [0002] In industrial production and daily life, there are many large and medium-sized storage tanks with a capacity of 70,000 or less than 70,000 cubic meters, such as large and medium-sized oil storage tanks, large and medium-sized LNG, and propylene storage tanks. Or a cylindrical steel structure welded by composite steel plates. Although the storage tanks store different media and different volumes, the materials used for the tank wall steel plates of the storage tanks may also be different, and the design of the steel plate specifications (thickness, width and length, etc.) are also different, even the same 50,000 cubic meters of oil st...
