possible to cut 2 annular plates using one single plate with 2.400 mm wide,and it considers that the total number of annular plates is always an even number.These aim to reduce the leftover material,to provide a limited amount of butt weld joints between the annular plates and to always lead to the symmetry of the quadrants,as shown in Fig.2.NFPA 59A-Proposed 2016 Edition Standard for theA.3.3.4.3.3 A membrane containment tank system consists of a thin metal liquid- and vapor-tight barrier resting against load-bearing thermal insulation and supported by a free-standing outer pre-stressed concrete container.In normal conditions,primary liquid and vapor containment is provided by a thin metallic barrier whichLecture 15C.1 Design of Tanks for the - UL FGGFor larger tanks (over 12,5 m diameter,according to BS 2654) a ring of annular plates is provided around the group of rectangular plates.The radial joints between the annular plates are butt welded,rather than lapped,because of the ring stiffening which the plates provide to the bottom of the shell.A typical arrangement is shown in Figure 4.

Large above-ground storage tanks (AST),On-site fuel tanks

To order.Above-ground storage tanks (AST) are meant for loading,storage and distribution of fluid products.Typically,large storage tanks are made vertical and are designed to store all kinds of liquid products and raw materials (including hazardous ones) in all industries and agriculture.I It is composed by radial girders (fig.3) and ring elements with cover plate which thickness is t ro=5 mm.The cover plate sheets are connected with butt welded joints.This ceiling can change the volume of gasholder and guarantee the gas storage under constantHow to Control the Welding Deformation of Large Storage For bottom plate of large storage tank ,the thickness of annular plate is larger,the length of weld seam is shorter; for center plates,if the center plate is not free to contract because of the external force during the welding,under the condition of no rigid fixation,the weld seam is made up and down,wave deformation inside the two sides
