API Std 650 petroleum storage tanks anchored with mechanical devices

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the API Std 650 petroleum storage tanks project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of API Std 650 petroleum storage tanks customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API Std 650 petroleum storage tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API Std 650 petroleum storage tanks, static storage loss and dynamic liquid level loss are common losses.

When the API Std 650 petroleum storage 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.
