A350 grade LF2 forgings API Std 650 aboveground steel oil storage tanks

The API 650 tank Standard has the built in flexibility to be used in building tanks to store a wide variety of products while ensuring the structural stability of the API Std 650 aboveground steel oil storage tanks tank.

The mechanical seal of floating roof API Std 650 aboveground steel oil storage tanks relies on mechanical force to press the sealing steel plate tightly against the tank wall, so that it can slide on the tank wall and avoid gap as far as possible. However, mechanical seal has high requirements for the geometry of storage tank and poor adaptability, so mechanical seal is rarely used in newly built floating roof API Std 650 aboveground steel oil storage tanks.
