API Std 650 partially anchored liquid-storage tanks backing

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.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 standard API 650 covers the design and calculation of different parts of the API Std 650 partially anchored liquid-storage tanks fuel tank. This specification is based on the knowledge and experience of buyers, manufacturers and users of API 650 welded storage tanks of different sizes and capacities. It is worth noting that the code requirements are minimal; stricter standards can be adopted for specific applications.Group consciousness is an important psychological factor for the formation of enterprise internal cohesion. The formation of API Std 650 partially anchored liquid-storage tanks enterprise group consciousness makes every employee of the enterprise regard their work and behavior as an integral part of the realization of enterprise goals, make them feel proud of themselves as a member of the enterprise, have a sense of honor for the achievements of the enterprise, and thus regard the API Std 650 partially anchored liquid-storage tanks enterprise as the community and belonging of their own interests.The normal operation of API Std 650 partially anchored liquid-storage tanks includes receiving oil, storing oil, sending oil and measuring oil. The correct use and operation of oil storage tank is directly related to the production safety and oil loss of oil tank. In order to use and operate the API Std 650 partially anchored liquid-storage tanks correctly, it is necessary to be familiar with and master the structure and performance of the API Std 650 partially anchored liquid-storage tanks and its accessories, such as the maximum storage capacity of the oil tank, the pressure range that can bear and the safety fabrication specification.
