Hot-Dipped Galvanizing
Sets standards for coating of pipe with zinc inside and outside by the hot-dipped process. Weight of coating must not average less than 1.8 oz. per square foot and not less than 1.6 oz. per square foot.
Permissible Variations in Wall Thickness
The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
Permissible Variations in Weights per Foot
Plus or minus 10%
Permissible Variations in Outside Diameter
Outside Diameter at any point shall not vary from standard specified more than:
