ASTM A106 pipe API 650 carbon and low-alloy steel tanks
API 650 petroleum storage tank has the advantages of high safety: the API 650 carbon and low-alloy steel tanksinner floating plate floats on the liquid surface, so that the liquid phase has no evaporation space, which can reduce the evaporation loss by 85% to 90%. At the same time, the API 650 petroleum storage tank blocks the air and liquid storage through the floating disk, which reduces air pollution and reduces the degree of fire risk.
Aftershock Level Earthquake (ALE)This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API 650 carbon and low-alloy steel tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.
Welders participating in the construction of API 650 carbon and low-alloy steel 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.
Do a good job of thought introduction based on people. Human based management is the most important link in standardizing employee behavior management. In daily behavior management, we should establish the central position of human and play an important role of human. Employees are not only the builders and exercisers of corporate culture, but also the executors of code of conduct. The code of conduct should be finally implemented into the thoughts and actions of employees.
