API Std 650 storage tank roof manholes

The mechanical seal of floating roof API Std 650 storage tank 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 storage tank.Steel Storage Welded Tank Certification
A certificate shall be supplied for each tank. This practice is intended to simplify keeping the records of future inspection in separate files for convenience.
