API 650 flat-bottom oil storage tanks required compression area at the roof-to-shell junction

In order to ensure the safety of the vertical storage tank, API 650 flat-bottom oil storage 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 flat-bottom oil storage 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 API 650 oil tank stiffener ring and backing strip, if used, are primary components, and they shall comply with the requirements of R.2.1. The API 650 flat-bottom oil storage tanks stiffener ring may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange. One rat hole with a minimum radius of 3/4 in. shall be provided at each longitudinal shell joint and ring juncture weld.

This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API 650 flat-bottom oil storage tanks storage of petroleum, petroleum products. and other liquid products.
