API Std 650 ground-supported liquid storage tanks scaffold-cable support

During heavy rain, closely observe the change of the water level in the storage area of the API Std 650 ground-supported 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 Std 650 ground-supported liquid storage tanks area to avoid lightning accidents. Observe the groundwater level of the API Std 650 ground-supported 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 Std 650 ground-supported liquid storage tanks from leaking and rusting due to untimely drainage.

The ring of API Std 650 ground-supported liquid storage tanks annular plates shall have a circular outside circumference, but may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with API Standard 620 R.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by welds as required by API Standard 620 5.9.5 except when a full penetration weld is used or required.

The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API Std 650 ground-supported liquid storage tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API Std 650 ground-supported liquid storage tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.
