Hot Water Piping Systems
Insul-Pipe Systems offers a full range of pre-insulated piping systems for underground hot water usages. The systems are comprised of a specified carrier pipe pre-insulated with polyurethane insulation and jacketing in either a PVC, HDPE, or FRP jacket.
The system features:
- Closed cell polyurethane insulation, offering the lowest available thermal conductivity and the best natural resistance to water penetration.
- Engineered coupling and fitting insulation kits providing the same level of moisture protection.
- This system can also be provided with prefabricated and pre-insulated fittings.
We can manufacture Insul-Pipe Systems Hot Water Systems to meet job specifications using a carrier pipe of:
- Steel
- Fiberglass
- Copper
- CPVC
- Ductile Iron
