API 650 special tank size

Fixed roof API 650 oil storage tank includes inner floating roof tank, which API 650 special tank can effectively prevent sand, rain, snow or dust from polluting the storage liquid. Under various weather conditions, API 650 oil storage tank can ensure the quality of liquid storage, which is called "all-weather API 650 special tank storage tank".

Generally, the building area temperature of the API 650 special tank should be considered before the tank design and construction. The temperature in the API 650 special tank building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API 650 special tank, the higher the corresponding pressure and the more volatile loss.

All API 650 special tank fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.
