API 650 self-anchored flat-bottom steel tanks bottom plates

According to API standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API 650 self-anchored flat-bottom steel tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API 650 self-anchored flat-bottom steel tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.

When welding API 650 self-anchored flat-bottom steel tanks, in order to avoid weld deformation, it is necessary to use corresponding welding process according to the type of steel used in the tank, such as welding requirements of steel plate, welding position, etc. Reasonable arrangement of the assembly sequence, the use of subsection back welding and jump welding method, strict control of welding process parameters, rigid fixation measures, take corrective measures for deformation compensation are necessary.

Low-pressure Storage Tanks for Liquefied Hydrocarbon Gases
API 650 self-anchored flat-bottom steel 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.
