API 650 special tank subject to a small internal pressure

Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API 650 special tank storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.

All oil tanks have service life. Due to the pressure of the oil stored on the tank and the corrosion of the oil and external environment on the tank, the oil storage tank will gradually become thin or crack after a long time. Due to the different materials and environment of API 650 special tank, the consumption of API 650 special tank is different, so it should be taken into account when evaluating the remaining service life of API 650 special tank.

Investigation of Subgrade
On actual steel storage tank sites to be used, test borings or test pits, or both, may be made at the direction of a competent engineer who will specify the number and location. They need not be equally spaced but should be laid out to uncover possible weak spots.
In general, test loadings of subgrade at the bottom of test pits need be resorted to only when such heavy loading as may be imposed by footings for major column supports for spheres or similarly elevated API 620 low-pressure tanks is specified. Results may be deceptive if average load-bearing capacity over a considerable area is wanted. All field data shall be recorded with maps, and copies shall be supplied to all engineers concerned with design, erection, and later operation.
