REHAU is offering two additional cross-linked polyethylene PEXa pipes in its municipal piping program. In addition to MUNICIPEX water service line, the expanded product range now includes MUNICIPEX pre-insulated for cold-weather applications and MUNICIPEX force main for wastewater applications. Specifically for water distribution in colder climates, the pre-insulated pipe provides an extra level of protection from freezing, which is particularly useful when laying pipe below the frost line is not possible. A MUNICIPEX carrier pipe is surrounded by a solid layer of CFC-free polyurethane foam insulation and a corrugated LDPE outer casing that provides superior durability. MUNICIPEX force main is used in publicly owned treatment works systems for conveying wastewater under pressure from the discharge side of a pump or pneumatic ejector to a discharge point. The pipe is color-coded with a green coating that helps installers easily identify wastewater applications. 703-777-5255; www.na.rehau.com.
