API standard 650 aboveground welded storage tanks ASTM specifications plates
Define the welding sequence of API standard 650 aboveground welded storage tanks 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.
Foundations and subgrade shall safely carry the weight of the tank API standard 650 aboveground welded storage tanks and its contents when the tank is filled with water to the highest level required for a hydrostatic test or other water-loading operations, even though the tank itself may be designed for some lesser density of liquid. However, in cases where the character of the soil justifies it and a competent soil expert advises it, allowance may be made for the relatively short duration and intermittent nature of the water loadings if suitable account is taken of all such loadings that may be expected to occur during the life of the tank, including not only those loadings that are incidental to periodic repetitions of the hydrostatic test in accordance with 7.18 but also water-filling operations for gas-freeing purposes.
Structural features of API 650 double-layer oil tank: steel glass fiber reinforced plastic double-layer structure, special processing method is adopted between the API standard 650 aboveground welded storage tanks internal steel shell and glass fiber reinforced plastic layer, so that a gap of 0.1 mm is created between the internal and external layers. Even if the API 650 oil storage tank leaks, it can ensure that the contained dangerous substances only flow in the gap, and will not immediately overflow the external environment.
