MUNICIPEX® pre-insulated water service pipe 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 water service consists of MUNICIPEX water service pipe surrounded by a solid layer of CFC-free polyurethane foam insulation and a corrugated LDPE outer casing. The insulation is bonded to both the outer casing and the MUNICIPEX water service pipe, increasing durability and flexibility. A conduit is fixed to the MUNICIPEX water service pipe allowing for the use of heat trace wires. Backed by a 25-year limited warranty for the water service pipe.
