Polymer TRENCHCOAT ® protective film bonds to galvanized steel both chemically and physically TRENCHCOAT Heavy Gauge Polymer Film (10 mil) Zinc Steel Alloy Layers Steel www. Contech. ES. com
Polymer CSP coated with TRENCHCOAT offers: • Excellent Adhesion • Chemical resistance to – Acids – Alkalis – Salts • Abrasion resistance • Weatherability • Water barrier imperviousness www. Contech. ES. com
Polymer Environmental Limits for 50 Year Service Life • p. H 3. 0 - 12. 0 • Resistivity > 250 ohm-cm • Abrasion: Good in levels 1 - 3; use invert treatments in level 4 www. Contech. ES. com
Abrasion is a function of flow velocity and bed load. In the absence of bed load, abrasion is not a factor. FHWA abrasion guidelines: Abrasion Level Abrasion Condition Bed Load Flow Velocity (fps) Level 1 Non – Abrasive None Low Level 2 Low Abrasive Minor (sand) <5 Level 3 Moderate Abrasive Moderate (sand & gravel) 5 - 15 Level 4 Severe Abrasive Heavy > 15 (sand, gravel & rock) www.

LONG-TERM FIELD INVESTIGATION OF POLYMER COATED CORRUGATED STEEL PIPE (2012) 1. The data continues to support guidance for a polymer coating “add-on” life of 80 years. 2. The polymer coating continues to protect the galvanized steel pipe in severe environmental and abrasion conditions beyond the design conditions. 3. In all of the pipes, less than 5% of the polymer had coating delamination. Written by: Elzly Technology Corportation Prepared for: NCSPA www. Contech. ES. com
