Welds for pads, lifting lugs, and other nonpressure parts, as well as temporary lugs for alignment and scaffolding attached to primary components, shall be made in full compliance with a welding procedure qualified in accordance with Q.6.1. Lugs attached for erection purposes shall be removed, and any significant projections of API 650 vertical welded storage tanks weld metal shall be ground to a smooth contour. Plate that is gouged or torn in removing the lugs shall be repaired using a qualified procedure and then ground to a smooth contour. Where such repairs are made in primary components, the area shall be inspected by the liquid-penetrant method. A visual inspection is adequate for repairs in secondary components.API 650 sets minimum requirements for the design, material, construction, and testing for aboveground, open and closed-top, cylindrical API 650 vertical welded storage tanks steel storage tanks in different capacities and sizes, roughly equating to the pressure of the atmosphere (not greater than the weight of the roof plates).We provide customers with demand support and better serve them. We are committed to actively meet the needs of customers, always keep in touch with them in a timely manner, leave a good impression for customers, and make customers satisfied through our unremitting efforts. Customer satisfaction is our most basic vision, striving to become the best steel product service provider in the worldThe foundation design of the API 650 vertical welded storage tanks should meet the requirements of foundation stability and deformation, that is, the API 650 vertical welded storage tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API 650 vertical welded storage tanks and cause distortion and deformation of the tank wall and bottom plate.
