Peka‑Pro DL (Dual Layer FBE Coating)

Peka‑Pro DL from Peka Chemie is a high‑performance dual‑layer FBE system engineered to outperform single‑layer coatings in both corrosion and mechanical protection. In this system, two layers of fusion‑bonded epoxy are applied sequentially to steel pipelines, offering a combined defense against cathodic disbondment, corrosion, impact damage, and mechanical abrasion during transportation, installation, and operation.

Introduced in 1999 as a cost‑effective alternative to multi‑layer systems for directional drilling applications, Peka‑Pro DL has proven reliability in harsh environments and demanding pipeline projects.

Key Advantages

• Outstanding corrosion and cathodic disbondment resistance
• High mechanical strength and abrasion resistance during handling and installation
• Enhanced performance compared to single‑layer FBE, especially in directional drilling
• Meets CSA Z245.20‑22 System 2B requirements
• Compatible with specialized topcoats (DL‑AR, DL‑AS, DL‑UF, DL‑UV) for project‑specific needs

Application Process

1. Surface preparation: Near‑White Blast (SA 2½, ISO 11124‑3), profile 50–100 μm
2. Preheat steel substrate to 210–240 °C
3. Apply first FBE layer (400 ± 50 μm) for corrosion protection
4. Apply second FBE layer (400 ± 50 μm) for enhanced mechanical protection
5. Controlled cooling to stabilize coating

Technical Highlights

• System Type: Dual‑layer fusion‑bonded epoxy
• Layer Thickness: 2 × 400 ± 50 μm
• Corrosion Resistance: Exceeds CSA Z245.20‑22 System 2B standards
• Abrasion Resistance: Proven under handling, backfilling, and horizontal drilling loads

Actual performance depends on proper surface preparation, film continuity, and curing parameters.

Standards & Compliance

• CSA Z245.20‑22 System 2B
• ISO 21809-2

Best Uses

• Pipeline systems in challenging mechanical and environmental conditions
• Directional drilling and HDD (Horizontal Directional Drilling) installations
• Oil, gas, and water pipelines requiring extended service life and reduced maintenance
