API Std 650 unanchored flat-bottom tank roof ladder

Inspection of API Std 650 unanchored flat-bottom tank bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API Std 650 unanchored flat-bottom tank bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API Std 650 unanchored flat-bottom tank, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API Std 650 unanchored flat-bottom tank bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.

Allowable Design Stresses
The maximum allowable design stresses for the API Std 650 unanchored flat-bottom tank materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.

The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, API Std 650 unanchored flat-bottom tank storage and storage platform tank materials and the selection of detection instruments, or the temperature of the API 650 oil storage tank area. The cost of storage has a direct impact.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the API Std 650 unanchored flat-bottom tank, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
