API 5L grade A pipe API standard 650 mechanically-anchored steel tanks

The seal of floating roof API standard 650 mechanically-anchored steel tanks is a device used to reduce the evaporation loss of the storage liquid in the annular space between the tank wall and the outer ring plate of the floating roof. The common sealing forms include mechanical seal, elastic filling seal, lip seal and secondary seal. No matter what kind of seal, the seal must be combined with the floating roof effectively to reduce the evaporation loss of the liquid in the floating roof.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API standard 650 mechanically-anchored steel tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API standard 650 mechanically-anchored steel tanks work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.

API 650 is used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API standard 650 mechanically-anchored steel tanks API 650 tanks with diameters between 8'-300', which are suitable for refineries, terminals, pipeline facilities and other projects.
