MUNICIPEX Pre-insulated is specially designed for water distribution in cold climates that require an extra level of protection from freezing, or when laying pipe below the frost line is not possible. MUNICIPEX Pre-insulated consists of REHAU MUNICIPEX PEXa carrier pipe surrounded by a solid layer of CFC-free polyurethane foam insulation and a corrugated LDPE outer casing. The outer casing “locks” the pipe firmly into the backfill while the insulation is bonded to both the outer casing and the MUNICIPEX carrier pipe, increasing durability and flexibility. A conduit is fixed to the MUNICIPEX pipe allowing for the use of heat trace wires.
