API 650 storage tanks repair

Tank cracks are common API 650 storage 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 650 storage tanks construction, which become obvious after the later use. Or in the process of using the API 650 storage tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.

Vertical Storage Tanks Security against Damage
The assemblies of relieving devices shall be secured against damage in service, the effects of storms, or mishandling. Access ladders and platforms that meet API 650 storage tanks plant safety rules are suggested.
Vacuum-relieving Devices
A vacuum-relieving device, when used, shall be as direct in inflow as possible with no pockets where moisture can collect, and it shall have no piping except a weather hood ahead of the inlet. An adequate vacuum-air inlet shall also be provided.

Compared with the fixed roof API 650 oil storage tank without API 650 storage 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 650 storage tanks product and pollutes the environment.
