Municipal and industrial pipeline systems are designed for long-term durability using standardized materials such as ductile iron, PVC, and HDPE. While these systems are built to prevent leakage and withstand environmental exposure, traditional insulation systems often become the weakest point by absorbing moisture, trapping water at joints, and accelerating corrosion under insulation (CUI).
Dragon Jacket manufactures fully encapsulated insulation systems engineered specifically for AWWA-based piping geometries, delivering long-term thermal performance without moisture intrusion or material degradation.
Designed for Standard Pipe Materials & Geometries
Dragon Jacket insulation is compatible with the most common municipal piping systems, including:
- Ductile Iron Pipe (DIPS) — AWWA C151
- PVC Pressure Pipe — AWWA C900 / C905
- HDPE Pipe (Fusion Systems) — AWWA C906 / ASTM F714
- Mechanical Joint (MJ) Systems — AWWA C111
Each component is manufactured to match standard OD tolerances, bell geometries, and fittings, ensuring consistent fit and performance.
Dragon Jacket systems accommodate DIPS and AWWA nominal pipe sizes from 2 – 54-inch+, maintaining uniform insulation thickness and thermal performance without field modification.
Engineered for Every Connection Type
Bell & Spigot (Push-On Joints)
HDPE Fusion Systems
Fusion joints create continuous, monolithic pipe runs that are typically not accessible after installation, making long-term UV and environmental protection critical for exposed HDPE systems. Dragon Jacket delivers a fully encapsulated barrier while allowing removal and reinstallation for QA/QC verification, repairs, or system modifications without damaging the insulation.
Mechanical Joint (MJ) Systems
Complete System Coverage
Dragon Jacket insulation is manufactured to cover every component within a municipal pipeline system, ensuring consistent performance across the entire installation.
Traditional insulation systems rely on layered materials that absorb water and degrade over time. Dragon Jacket’s encapsulated design creates a sealed outer shell that prevents water ingress and protects the underlying piping system. This helps:
- Reduce risk of freezing in low or stagnated flow scenarios
- Prevent corrosion under insulation (CUI)
- Extend the service life of both insulation and piping
