Aluminum dome roofs API 650 SUG I tanks
Strictly control the welding groove forming of API 650 SUG I tanks: in order to ensure the geometric dimension of assembly and good welding of welding seam, before hoisting and laying, the edge of all metal vertical storage tank plate shall be polished by grinder, and the flatness of plate shall be ensured according to the design requirements. Strictly control the size of API 650 SUG I tanks weld assembly: measures must be taken to strictly control the assembly size of metal vertical tank bottom plate during assembly.
API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at API 650 SUG I tanks design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.
API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 SUG I tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 SUG I tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.
