Abstract: The basic performance and composition of both three-layer polyethylene anticorrosive coating (3PE) and dual powder fusion bonded epoxy systems(DPS), especially their abrasion resistant, elastic modulus, spray process and quality control, pipeline gap coating-repair & security, cathodic protective compatibility and economy were compared in detail.The result showed that DPS, as a substitution of the existing 3PE in China, was superior to 3PE in overall protective performance capable of meeting requirement in actual application.
