9 3 2015 CALPEX district heating pipe CPX Subject to technical changes System description 1 General CALPEX district heating pipe is the registered trade name for a flexible pipe system from Brugg Pipe Systems specifically designed for the low temperature use It is ideal for use in small and midsize district and local heating networks in industrial and agricultural applications for drink ing water supplies sewage systems cooling systems and swimming pool installations CALPEX district heating pipe has a carrier pipe made of cross linked polyethylene PEXa This material was selected because of its excellent thermal and mechanical properties It is a corrosion proof and chemically resistant material The product is free of harmful substances making it exceptionally environment friendly The PEXa pipe in the heating series is equipped with an oxygen diffusion barrier EVOH The thermal insulation is CFC free flexible rigid polyurethane foam with excellent insulation values The bending capability of CALPEX district heating pipe means that it is generally possible to pass over or under existing supply pipes and obstacles can be easily bypassed With CALPEX district heating pipe users can choose the shortest pipe route without the restric tions required by the classical method of pipe construction The flexible CALPEX district heating pipe is delivered to the site continuously in coils or on a cable drum Long delivery lengths enable pipes to be laid in the ground largely without joints This means that the pipe trench can be considerably narrower This in turn allows considerable savings on underground work especially as regards DUO pipes Taking account of the very short time required for installation CALPEX district heating pipe is not only the technically ideal solution but also the key to saving time and expense when setting up district heating networks less co ordination is required on site and the pipes are laid simply and quickly The physical properties of the PEXa pipe combined with the composite insulation mean that thermal expansion can be ignored when using this product Installing the connecting pieces is very simple The joints are fitted quickly and reliably with conventional screwed connectors compression joints or electro fusion joints The wide range of accessories ensures that solutions can be chosen for every possible situation CALPEX district heating pipes are manufactured according to the current standard EN 15632 1 2 2 Range of applications Heating pipe series 5 SDR 11 Max temp for continuous operation TBmax 80 C Max permitted operating temp Tmax 95 C fluctuating Max permitted operating pressure p 6 bar see sheet CPX 1 110 Sanitary pipe series 3 2 SDR 7 4 Max temp for continuous operation TBmax 80 C Max permitted operating temp Tmax 95 C fluctuating Max permitted operating pressure p 10 bar see sheet CPX 1 110 1 100
