API standard 650 cylindrical liquid-storage tank typical joints
The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API standard 650 cylindrical liquid-storage tank storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.
The ring of API standard 650 cylindrical liquid-storage tank annular plates shall have a circular outside circumference, but may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with API Standard 620 R.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by welds as required by API Standard 620 5.9.5 except when a full penetration weld is used or required.
Due to irregular operation of API standard 650 cylindrical liquid-storage tank welding, there are many weld deformations during the construction process. Before specific operations, most construction units have formulated relatively complete construction plans and set up special welding process instructions, but the operators have not fully performed welding in accordance with various process guidance requirements and construction specifications, resulting in some quality problems of oil storage tanks. How can we reduce or even avoid this kind of situation?
The formula of enterprise success is: success = strategy × organizational capability, that is, having the right direction and strong organizational capability. The core competence of an enterprise depends on three pillars: first, talents (talent echelon); second, core values of enterprise culture; third, organizational governance model. If the enterprise is a tree, then the core values of talents, corporate culture and organizational governance mode are just like the root of the tree. With them, the enterprise will flourish and grow forever.
In the process of API standard 650 cylindrical liquid-storage tank steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose API standard 650 cylindrical liquid-storage tank different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
