API 650 cylindrical welded storage tanks lap-welded bottom joints

Prefabricating API 650 cylindrical welded storage tanks components before construction can improve construction efficiency, save time and cost, and is currently a common method for the construction of large vertical storage tanks. The main prefabricated components of a large vertical API 650 cylindrical welded storage tanks include the tank body, the storage tank wall, the top of the storage tank, the bottom of the storage tank, and the accessories of the storage tank. The prefabrication of the components should follow a reasonable workflow, and carry out appropriate heat treatment and testing, so as to improve manufacturing accuracy.Any joints between the adjacent sections of API 620 oil storage tank stiffening rings, as shown in Figure Q-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 joint ends. All weld passes shall be started at the rat hole and other weld joint ends and shall be completed by moving away from these ends. Passes shall be overlapped away from edges to provide a smooth continuous weld.API standard 650 is typically used for carbon, stainless steel and aluminium API 650 cylindrical welded storage tanks tanks located in terminals, refineries, pipelines and other process facilities. Both have different pressure and temperature parameters as well. Your choice of model will depend on you and/or your client s particular needs.Integrity, cooperation and innovation, positive and competitive, healthy and abundant are the company's core values.
