API standard 650 mixed material tanks bottom joints
This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API standard 650 mixed material tanks design, supply, fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached Datasheets and/or Drawings.
Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API standard 650 mixed material tanks material specimens shall be of sufficient length to locate the notch in the heat-affected zone after etching. The notch shall be cut approximately normal to the material surface to include as much heat-affected zone material as possible in the resulting fracture. Impact test specimens shall be cooled to the temperature stated in Q.22.
The foundation design of the API standard 650 mixed material tanks should meet the requirements of foundation stability and deformation, that is, the API standard 650 mixed material tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API standard 650 mixed material tanks and cause distortion and deformation of the tank wall and bottom plate.
