API standard 650 carbon steel storage tanks roof flotation test

Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API standard 650 carbon steel storage tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.

Crack treatment of API standard 650 carbon steel storage tanks weld area: find out the crack tip with ray or ultrasonic flaw detection, drill cut-off holes at both ends of the crack with the cut-off method, the hole depth is slightly greater than the crack depth, or groove (crack stop groove) is made by angle grinder at both ends of the crack, shovel and grind the whole crack, and grind it into a suitable groove; use radiographic inspection and dye detection to verify that the crack has been completely excavated, and finally repair welding.

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.

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API standard 650 carbon steel storage tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API standard 650 carbon steel storage tanks steel transportation industry.
