1100 aluminum bar API standard 650 self-anchored tank

Low-pressure storage tanks for Liquefied Hydrocarbon Gases
API standard 650 self-anchored tank 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.

Supply covers for API standard 650 self-anchored tank connections specified with the service covers remaining in place following tests. For API 650 tank connections not specified to be supplied with service covers, the test covers may be removed after testing.

Define the welding sequence of API standard 650 self-anchored tank bottom plate: the welding sequence of metal vertical storage tank shall be carried out according to the procedure required by the welding scheme. Spot welding shall be consistent with the formal welding requirements, and no spot welding shall be carried out for the weld not welded. Back bar should be added to prevent deformation when welding the full length seam of middle plate, butt joint of edge plate and turtle shell joint.
