API standard 650 aboveground welded storage tanks external pressure

The mechanical seal of floating roof API standard 650 aboveground welded 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 standard 650 aboveground welded storage tanks.

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. When a group of crude oil storage tanks is being constructed on one order and in one general location some specific form of reporting other than a API standard 650 aboveground welded storage tanks Manufacturer’s report may be preferred by both parties. It would seem desirable that the details on each contract be settled when the purchase order is placed; if they are not covered in the proposal, then they shall be given as information in the inquiry.
