Pipe Insulation for Exposed
Water Mains, Sewer Mains, and Bridge Crossings
A fully encapsulated insulation system for exposed water and sewer pipelines that simplifies installation, reduces maintenance, and delivers long-term freeze protection.
The Challenge
The Dragon Jacket Approach
Dragon Jacket is a fully encapsulated insulation system that combines insulation and protective jacketing into a single factory-fabricated assembly.
Why Dragon Jacket is Different
Traditional Insulation |
Dragon Jacket |
|---|---|
| Insulation, jacketing, vapor barrier layers | Integrated assembly |
| Specialty insulation trade required | Utility crews can install |
| Difficult to remove and replace | Removable and reusable |
| Moisture intrusion common | Encapsulated & moisture-resistant |
| Fabricated in-field | Prefabricated fitment |
Engineers
• Reduce risk of insulation failure due to moisture intrusion
• Improve freeze protection reliability for exposed pipelines
• Simplify specifications with a fully encapsulated system
• Support inspection and maintenance access without destroying insulation
• Improve lifecycle performance in exposed environments
Contractors
• Existing utility crews can install the system
• Reduced trade coordination
• No separate vapor barrier or field jacketing
• No insulation subcontractor required for many projects
• Installs up to 16× faster than traditional systems
Distributors
• Simplify procurement for contractors and owners
• Consolidate insulation into the waterworks material package
• Support engineers with specification-driven solutions
• BABA-compliant and Made in USA
• Differentiate from competing waterworks suppliers
Owners
• Lower lifecycle maintenance costs
• Reduced risk of moisture-related insulation failures
• Easy access for inspection and maintenance
• Long service life in exposed environments
• Reduced project complexity during construction
Real Project Examples
North Idaho Water Main
24-inch ductile iron bridge crossing insulated by the contractor’s construction crew without a specialty insulation contractor.
Salt Lake City Temporary Sewer Main
24-inch temporary fused PVC sewer bypass installed by contractor personnel to maintain service through winter conditions.
Missouri Water Main
1,800 LF of exposed bridge crossings insulated in approximately 65 man-hours.
Washington Water Main
6-inch ductile iron bridge crossing insulated by civil construction crew without a specialty insulation contractor.
