16 12 2013 EIGERFLEX CPE Subject to technical changes 3 100 System description 1 General EIGERFLEX is Brugg Pipe Systems protected name for a flexible pre insulated cold water pipe featuring an integrated frost protection strip FPC This pipe system is especially suitable for cold water and waste water pipes which can either be installed above ground or at depths with frost The EIGERFLEX cold water pipe features a medium pipe produced from high density polyethy lene PE100 as per standard DIN EN 12201 Polyethylene pressure pipes are the standard for drinking water and waste water systems and also for the gas supply sector and they are excellently suited to the areas of application just mentioned The pipes are joined by means of standardised screwed connectors mechanical pipe couplings with normal commercial electro welded fittings or by means of polyfusion welding technology The heat insulation consists of CFC free flexible rigid polyurethane foam with excellent insu lating properties The bending capacity of the flexible EIGERFLEX cold water pipe means that it can be adapted to all pipe routing conditions without problems It is possible to pass over or under existing supply pipes and obstacles are easily bypassed With flexible EIGERFLEX cold water pipe you can choose the shortest pipe route without having to consider classical pipe construction methods The self limiting frost protection strip FPC has direct contact to the medium pipe within the heat trace channel and a power capacity of 18 W m EIGERFLEX cold water pipe is prefabrica ted as appropriate and supplied in the required lengths it always offers the same performance regardless of the quantities ordered The maximum length of the heating circuit varies according to the cut in temperature which must be controlled by a thermostat The desired length of flexible EIGERFLEX cold water pipe is delivered to site in continuous form either in rings or on a cable drum Thanks to the generous delivery lengths pipes can be laid largely without connection points in the ground so the width of the pipe trench can be considerably reduced Substantial savings are possible because underground construction work is minimised and installation is fast as well as simple 2 Range of applications Max continuous operating temperature TBmax 30 to 20 C Max permitted operating pressure p max 16 bar
