API Std 650 fixed roof tanks diameter

Compared with the fixed roof API 650 oil storage tank without API Std 650 Fixed roof tanks floating roof, there is no evaporation space. In principle, this eliminates the so-called "large breathing loss". Evaporation not only causes the loss of product quantity, but also affects the quality of API Std 650 fixed roof tanks product and pollutes the environment.

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 fixed roof 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.

Tank cracks are common API Std 650 fixed roof tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API Std 650 fixed roof tanks construction, which become obvious after the later use. Or in the process of using the API Std 650 fixed roof tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.
