Scope
According to the characteristics of γ-ray panoramic exposure of steel spherical storage tanks (hereinafter referred to as spherical tanks), this standard is formulated to ensure the quality of spherical tank inspection. This standard applies to the on-site detection of γ-ray panoramic exposure of fusion welded joints of spherical tanks with nominal thickness of 10mm-100mm, nominal volume of 50m3-10000m3, and materials of carbon steel, low alloy steel, and stainless steel; it does not apply to spherical tanks affected by nuclear radiation, non-fixed (such as vehicle-mounted or ship-mounted) spherical tanks, expansion-formed spherical tanks, and double-shelled spherical tanks. The γ-ray detection technical grade of this standard shall not be lower than the provisions of Class AB in the current industry standard "Non-destructive Testing of Pressure Equipment - Part 2: γ-ray Testing" JB/T 4730.2-2005.
