API Std 650 carbon and low-alloy steel tanks non-armored hose-type drains
All edges of the inner wall of the API 650 petroleum storage tank to be lined or coated must be rounded and flat to a minimum radius of 3mm. The API Std 650 carbon and low-alloy steel tanks internal welding seam must be completely sealed welding, with a smooth surface and no air holes, air pockets and local protrusions. Remove welding spatter. As specified in API 650 petroleum storage tank design drawings, the seller must perform additional surface treatment.
The main contents of safety inspection for atmospheric storage tank, API Std 650 carbon and low-alloy steel tanks are to see whether the tank foundation is sunk, whether the tank is corroded, whether there are cracks in the tank body and bottom, whether there is concave convex phenomenon on the top and wall of the tank, whether the accessories of the storage tank are in good condition, etc. After the API Std 650 carbon and low-alloy steel tanks safety inspection and detection, the defects found in the tank should be handled according to the inspection rules in time to ensure the normal and safe use of the storage tank in the later stage.
Foundations and subgrade shall safely carry the weight of the tank API Std 650 carbon and low-alloy steel 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.
