Mechanical loads on API 650 floating-roof tanks

The Standard has gained international recognition and is the standard of choice of most builders of large liquid above ground API 650 floating-roof tanks storage tanks. One reason for this is that the API 650 Standard was created and is revised by API committees comprised of the world s best tank structural engineers who also rely on the experience of tank owners and tank construction companies.

In order to ensure the safety of the vertical storage tank, API 650 floating-roof tanks, the supplier should inspect the tank carefully before delivery. The failure of the tank body is mainly due to the weld and crack of the product. The inspection of API 650 floating-roof tanks, vertical storage tank weld and microcrack is mainly to inspect the appearance forming quality of weld. The inspection contents include weld leg height, undercut, welding deformation, weld bead, arc pit, weld straightness, etc., as well as the internal quality of weld, such as slag inclusion, porosity, incomplete penetration, crack, incomplete fusion, etc.

The tank shall be filled with water to the design liquid level unless height is limited as noted in API 620 standard Q.8.1. After the tank is filled with water and before the pneumatic pressure is applied, anchorage, if provided, shall be tightened against the hold-down brackets. All welds in the API 650 floating-roof tanks shell, including the corner weld between the shell and the bottom, shall be visually checked for tightness.
