API 650 self-anchored storage tanks annular ring requirements

API 650 internal floating roof API 650 self-anchored storage tanks tank can be used to store gasoline, jet fuel and other volatile oil products, as well as aldehydes, alcohols (methanol, ethanol), ketones (acetone), benzene (benzene, toluene, xylene, styrene) and other liquid chemicals.

Corrosion of the API 650 self-anchored storage tanks body caused by external conditions such as high temperature, rain, humidity, or inadequate anti-corrosion measures of the oil storage tank itself, the water-bearing deposits in the oil storage tank caused corrosion and perforation of the inner surface of the oil storage tank bottom plate. Defects fatigue cracks caused by stress, with the accumulation of time, the compressive strength of the API 650 self-anchored storage tanks body decreases and corrosion cracks occur.

Low-pressure Storage Tanks for Liquefied Hydrocarbon Gases
API 650 self-anchored storage tanks Primary Components: In general, primary components include those components that may be stressed to a significant level, those whose failure would permit leakage of the liquid being stored, those exposed to a refrigerated temperature between –60°F and –270°F, and those that are subject to thermal shock. The primary components shall include, but will not be limited to, the following parts of a single-wall tank or of the inner tank in a double-wall tank: shell plates; bottom plates; roof plates; knuckle plates; compression rings; shell stiffeners; and manways and nozzles including reinforcement, shell anchors, pipe, tubing, forgings, and bolting.
