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 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API 650 ground supported liquid storage tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.The company's quality is first, the price is reasonable, the construction period is guaranteed, and the purpose of abiding by the contract, our steel API 650 ground supported liquid storage tanks products have received high recognition from customers from the world.

To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API 650 ground supported liquid storage tanks. How to reasonably control the welding process quality of oil storage tanks?
