API Std 650 aluminum tanks erection requirements

API 650 Tanks in which liquid fluids are stored and designed to withstand atmospheric pressure operation, less than 18 kPa, or internal pressures not exceeding the weight of the API Std 650 aluminum tanks roof, with temperatures no higher than 93, 3 C are included in the scope of this design code.

The cone slope of the completed API Std 650 aluminum tanks foundation is 15/1000 for the general foundation and less than 35/1000 for the soft foundation. After the foundation settlement of the storage tank is basically stable, the surface slope must be greater than eight thousandths. The edge of the tank bottom should be more than 0.3 meters higher than the surrounding ground. Above the ground, the tank bottom leakage detection tube should be drawn from the foundation sand cushion and cross the foundation ring wall or the slope protection surface. The circumferential distance should be less than 20 meters, and each API Std 650 aluminum tanks should have at least 4 detection tubes.

Ultrasonic Examination of Butt-welds in Plates
Butt-welds in all tank wall courses subjected to a maximum actual operating membrane tensile stress, perpendicular to the welded joint, greater than 0.1 times the specified minimum tensile strength of the API Std 650 aluminum tanks plate material shall be completely examined.
Butt-welds in API 620 oil tank wall courses subjected to maximum actual operating membrane tensile stress, perpendicular to the welded joint, less than or equal to 0.1 times the specified minimum tensile strength of plate material shall be spot examined in accordance with Figure Q-2.
