Seismic design for API Std 650 cylindrical welded storage tanks
API 650 petroleum storage tank body design is mainly the design of tank bottom, API Std 650 cylindrical welded storage tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API Std 650 cylindrical welded storage tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.
Temperature Range: The provisions in this appendix are considered suitable for API Std 650 cylindrical welded storage tanks design metal temperatures from + 40°F to –60°F, inclusive. In general, refrigerated tank primary components include those components whose failure would result in leakage of the liquid being stored, those exposed to the refrigerated temperature, and those subject to thermal shock. Further definitions of such components are provided in API Standard 620 tank R.1.4.2 and R.1.4.3.
Welders participating in the construction of API Std 650 cylindrical welded storage tanks must pass the examination and perform welding within the validity period of the qualified items. Special operators such as on-site maintenance electricians, cranes, and shelf workers must hold job certificates. All oil pipelines need to use arc welding for bottoming and electric welding to ensure the welding quality. Oil tanks and process pipelines must be tested for non-destructive flaws in accordance with the flaw detection ratios and methods required by the design and acceptance specifications. The flaw detectors must be certified.
Company through its own API Std 650 cylindrical welded storage tanks website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.
