Anotace textu normy ASTM A972/A972M-00(2021) :
This specification covers standard requirements for pipe piles with protective fusion-bonded epoxy powder coating applied by the electrostatic spray, flocking, or fluidized bed process. The surfaces of steel pipe piles to be coated shall be precleaned, as required. Steel surfaces shall be cleaned by abrasive blast cleaning to near-white metal. Prior to application of the fusion-bonded epoxy powder coatings, raised silvers, scabs, laps, sharp edges, or seams shall be removed using abrasive grinders. The powder coating shall be applied to cleaned steel surfaces before visible oxidation occurs. To achieve the required coating thickness, the steel shall be preheated prior to applying the powder coating. The heat source shall not leave a residue or contaminant on the steel surfaces. If oxidation occurs, the steel shall be cooled to ambient temperature and recleaned before applying the powder coating. The steel pipe piles shall be tested and shall meet the requirements for coating thickness and coating continuity.
