API Std 650 unanchored liquid-storage tanks lap joint
API Std 650 unanchored liquid-storage tanks any joints between the adjacent sections of stiffening rings, as shown in Figure R-1, shall be made so that the required moment of inertia of the combined ring-shell section is provided. Weld joints between adjacent sections shall be made with full-thickness and full-penetration butt-welds. Stiffening-ring butt-welds may employ metal backing strips. Backing strips and the associated welding shall be made in a manner that provides a smooth contour in the rat hole and all other weld joints ends. All weld passes shall be started at the rat hole.
Large net shell API 650 tanks or net shell of tank API Std 650 unanchored liquid-storage tanks is a tank top for the surface grid structure and the physical structure form of truss structures, thin shell structure is reasonable, mainly for the top using triangle net shell, socket type net shell or meridian reticulated shell technology for the design of API Std 650 unanchored liquid-storage tanks large-scale tank top, its great spanning capacity and uniform stress, good rigidity, less material, convenient assembly, safe and reliable.
In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate API Std 650 unanchored liquid-storage tanks for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 API Std 650 unanchored liquid-storage tanks and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
}The structure of the API Std 650 unanchored liquid-storage tanks foundation mainly includes the insulating anticorrosion layer on the top surface of the foundation, the tank wall support, the edge retaining structure, the sand cushion, the oil and water barrier, the detection signal tube and other structures. The construction materials and requirements of each basic structure of the storage tank are different. After the structure of the API Std 650 unanchored liquid-storage tanks foundation is built in accordance with the construction requirements, the settlement of the storage tank foundation needs to be observed, and the uneven settlement value of the storage tank foundation should be within the allowable safety range.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
