API Std 650 stainless steel storage tanks thickness of shell plates

According to the structure type of floating roof, floating roof API Std 650 stainless steel storage tanks can be divided into internal floating roof tank and external floating roof storage tank. The internal floating roof tank is a floating roof tank with tank roof. The top is the combination of dome roof and floating roof, the external is dome roof, and the internal is floating roof. There is no vault on the top of the External floating roof tank, only a top plate floating with the storage liquid. The common feature of the inner floating roof tank and the outer floating roof tank is that both of them can reduce the evaporation loss of the storage liquid.In this project, the area of tank wall used is of the same construction, material, and geometry as that described in F.1.3.1 except that the thickness of the plate is 3/8 in. The wall is stressed in the same manner as is described in F.1.3.1. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 8000 lbf/in.2.
The problem in this example is to find the maximum allowable (latitudinal) compressive stress value for the given conditions, in conformance with the provisions of API 620 tank standard 5.5.4.5.
Solution: As determined from Table 5-1, the maximum allowable tensile stress value, Sts, for ASTM A285, Grade C, steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R in this situation is R1, or 75 in.API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API Std 650 stainless steel storage tanks is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API Std 650 stainless steel storage tanks API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.Enterprise style: unity, pragmatism, responsibility, and endeavorOperation Policy: realistic management, innovative technology, high quality, fast efficiency, low cost and complete service.
