Behavior of API Std 650 ground supported tanks
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.
One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API Std 650 ground supported tanks is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.
We have lots of successful cases, for example in July 2015, we exported 5714 tons ASTM A36 mild steel plate to Peru. After receiving the plates and putting then into use, our customer spoke highly of the ASTM A36 mild steel plate quality. In addition, the customer also introduced us an Venezuela customer, who bought 933 tons A36 steel API Std 650 ground supported tanks plate from us. And then in Mar. 2016, due to the first cooperation in July 2015 is very successful. The customer is very satisfied with our product quality and comprehensive service. This time, the customer place an 3989 tons order directly.
}Prefabrication requirements of large vertical API Std 650 ground supported tanks accessories: the prefabrication shall be deepened as far as possible in strict accordance with the requirements of construction drawings and specifications, according to the principle of convenient installation and construction, as much as possible to reduce the installation workload, especially the workload of high-altitude operation. The prefabricated accessories shall be strictly inspected to ensure the quality and make marks. In addition, effective measures should be taken to prevent deformation, damage and corrosion during storage, transportation and stacking on site.
The results of adopting two-level API Std 650 ground supported tanks service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and API Std 650 ground supported tanks after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
