Dual‑layer Fusion Bonded Epoxy (FBE) system with exceptional abrasion and gouge resistance, engineered for pipelines exposed to severe mechanical stress during handling, transport, and installation.
Peka‑Pro DL‑AR from Peka Chemie is a specialized Dual Layer FBE coating system developed to protect steel pipelines against mechanical damage caused by laying, handling, backfilling, and horizontal directional drilling (HDD). The system combines the proven corrosion resistance of Peka‑Pro Pr primer with an abrasion‑resistant topcoat, delivering long‑term integrity under extreme operating conditions.
Its special formulation ensures optimum protection against gouges and surface wear, making it ideal for environments with high mechanical loads and abrasive soil conditions. DL‑AR meets the rigorous requirements of IGS‑M‑TP‑026 and CSA Z245.20‑22 System 2B standards.
