API 650 anchored tanks design metal temperature

API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API 650 anchored tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.

Prefabricating API 650 anchored 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 anchored 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.

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.

When the API 650 anchored tanks top shell course is the minimum thickness indicated in 5.10.4, Table 5-6 and Figure 5-6, details a – e, h and i, the minimum anchorage shall be designed for normal loads as specified by the Purchaser and by this standard. See 5.11.2.3 for the allowable stress. When the top shell course is thickened beyond the minimum thickness provided in Table 5-6 or as in Figure 5-6, details f and g, or a knuckle is used, the minimum anchorage shall be designed for three times the internal design pressure. The allowable stress for this loading is 90% of the minimum specified yield strength of anchorage material.
