505 with wire

THERMACOR’S DUO-THERM “505” is a factory-fabricated, pre-insulated piping system that incorporates polyurethane foam and a rugged, non-corrosive, High Density Polyethylene (HDPE) jacket with a Class A Steel Conduit System.

DUO-THERM is ideal for the distribution of high pressure steam, condensate, and high temperature hot water. The system is built around a typical Class “A”, steel-in-steel system, but is enhanced with an outside layer of polyurethane foam and a non-corrosive HDPE jacket. The HDPE jacket ensures watertight integrity of the insulation envelope, eliminating the need for cathodic protection. The system is pre-fabricated and pre-engineered as a complete system that is drainable, dryable, and air testable with total manufactured components: pipes, loops, ells, tees, end seals, gland seals, and anchors. The system is built to withstand heavy traffic/earth loads, high water tables, and the most corrosive of soils. An ERM leak detection system can be embedded in the foam insulation to detect groundwater intrusion.
