Seismic Use Group for API Std 650 welded aluminum storage tanks

Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API Std 650 welded aluminum storage tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API Std 650 welded aluminum storage tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

The bottom plate of the vertical API Std 650 welded aluminum storage tanks directly contacts with the foundation soil, which is suitable for the flexible foundation, and its settlement characteristics are quite different from that of the rigid foundation. For the settlement calculation of the foundation of a vertical API Std 650 welded aluminum storage tanks, the one-way compression layered sum method can be used. The calculation method is to divide the foundation soil into several layers of compression within the calculation depth of the foundation settlement, and then find the sum. The calculation method of the compression amount of each layer is the same as the calculation method of the compression amount under the condition of no lateral deformation.

Company through its own API Std 650 welded aluminum storage tanks website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.
