When repairing the anti-corrosion layer of a 3PE pipeline, the repair material should ideally match the original anti-corrosion layer. Commonly used repair materials include polyethylene repair patches and pipeline anti-corrosion repair sticks.

Current novel repair solutions often involve viscoelastic anti-corrosion tape or viscoelastic anti-corrosion paste combined with polymer tape. (Repair sticks and viscoelastic anti-corrosion paste are generally used as auxiliary repair materials to fill larger damage cavities).
