Fabrication requirements for API standard 650 welded storage tanks

This standard applies only to API 650 tank API standard 650 welded storage tanks whose entire bottom is uniformly supported and to API 650 tank in non-refrigerated service that have a maximum design temperature of 93°C (200 °F) or less.

Low-pressure Storage Tanks for Liquefied Hydrocarbon Gases
API standard 650 welded 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.

Oil storage tank with floating roof structure: The floating roof in the API standard 650 welded storage tanks oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is small, the exhaust volume is low, and the breathing loss is very small. That can reduce the volatilization loss caused by the "big breath" of the API standard 650 welded storage tanks. Strengthen the inspection and maintenance of API standard 650 welded storage tanks: regularly check the sealing conditions of oil storage tanks, and check and maintain important auxiliary equipment to ensure good sealing performance.
