API standard 650 anchored liquid-storage tanks hydrostatic testing requirements
Charpy V-notch specimens shall be taken from the weld metal and from the heat-affected zone of the welding procedure qualification test plates or from duplicate test plates.Weld metal impact specimens shall be taken across the weld with the notch in the API 620 oil tank material weld metal. The specimen shall be oriented so that the notch is normal to the surface of the material. One face of the specimen shall be substantially parallel to and within 1/16 in. of the surface.
The reticulated API standard 650 anchored liquid-storage tanks shell API 650 storage tank is an important large-span space structure with high safety. Generally, the large-scale API 650 storage tank with a diameter of 21-60 meters or a volume of more than 20000 cubic meters should adopt the reticulated shell technology, which has been widely promoted and adopted in the world and China's petrochemical industry for more than 30 years.

}During heavy rain, closely observe the change of the water level in the storage area of the API standard 650 anchored liquid-storage tanks. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API standard 650 anchored liquid-storage tanks area to avoid lightning accidents. Observe the groundwater level of the API standard 650 anchored liquid-storage tanks area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API standard 650 anchored liquid-storage tanks from leaking and rusting due to untimely drainage.
