API 650 SUG II tanks spectral acceleration coefficients
The hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 SUG II tanks standing outdoors. We must find some simple and effective methods to protect the API 650 SUG II tanks in order to make them safely spend the summer. As a API 650 SUG II tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.
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.
The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API 650 SUG II tanks tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API 650 SUG II tanks work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
