API standard 650 welded steel storage tanks mechanical shoe seals

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API standard 650 welded steel storage 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.

Welding of API 620 Steel Storage Tank Primary Components
The following primary components shall be joined with double butt-welds that have complete penetration and complete fusion except as noted:
Longitudinal and circumferential shell joints and joints that connect the annular bottom plates together. When approved by API standard 650 welded steel storage tanks Purchaser, these may be welded from a single side provided temporary non-fusible backing is used with complete penetration and complete fusion. Both sides of the joint shall be 100% visually examined as specified in 7.15.5.

X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as API standard 650 welded steel storage tanks. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of API standard 650 welded steel storage tanks etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
