For detailed information, please refer to DIN 1988 / DIN EN 806.” Sources: https://www.fraenkische.com/en/faq/building-technology ### [Is it necessary to insulate alpex multilayer composite pipes for cold water lines against condensation water?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-b66b209e1b63a871cded) “Yes, insulation of cold drinking water pipes is required according to DIN 1988-200 tab. 8 and 9 in order to prevent condensation and to protect drinking water from warming-up due to elevated ambient temperatures. Pipes that come into contact with the structure (floating, screed, etc.) must be protected with at least one layer of insulation (pipe with protective sheathing).” Sources: https://www.fraenkische.com/en/faq/building-technology ### [Are alpex installations possible with de-mineralised water?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-2e064bcd3dcdc67ee756) “No, since the installation of multilayer composite pipe systems usually includes brass fittings. Brass fittings may be affected by corrosion damage in connection with de-mineralised water (aggressive).” Sources: https://www.fraenkische.com/en/faq/building-technology ### [Are alpex installations possible with softened water?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-142451e2496dcd23c91d) “Yes, alpex installations (pipe + PPSU + brass) can be operated with softened water of up to 0°dH. The limit value for sodium ions of 200 mg/l may not be exceeded during softening.” Sources: https://www.fraenkische.com/en/faq/building-technology ### [Up to which max. heat capacity can I connect alpex pipes?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-e9efa9d8bd21326eeffd) “Please refer to the Technical information for detailed alpex performance and pressure loss tables for heating applications.” Sources: https://www.fraenkische.com/en/faq/building-technology ### [Is it possible to install FBY pipes in concrete?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-05ff8c775049a7cdc473) “No. Here, clear standard-related statements concerning mechanical properties of the pipes are provided. According to IEC, only our FFKuS-EM-F, or products with similar or better properties can be used.” Sources: https://www.fraenkische.com/en/faq/electrical-systems ### [Does the range of products by FRÄNKISCHE include an uncoil system for conduits?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-e0d3f44254c74196d234) “No. To this end, high-quality products by Lübbering are available. www.luebbering.de” Sources: https://www.fraenkische.com/en/faq/electrical-systems ### [What does "pliable, self recovering" stand for?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-10dbd817ea4e9342fa61) “Pliable, self recovering pipes are classified 3 in the fifth digit, i. e. the pipes have a maximum deformation of 50% (based on the outside diameter). This permissible deformation reduces the inside diameter by 72%, which means that the inside diameter of a size 25 pipe shrinks from 17.9 mm to 5.0 mm.” Sources: https://www.fraenkische.com/en/faq/electrical-systems ### [What surfaces can the ReMo click rail be mounted on?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-6c3bc0e4f3d735e0579f) “The surface for mounting should be dry and dust-free. The temperature should be between 18 °C and 35 °C. The rail has an immediate holding force, its adhesive force, however, is not designed for continuous loads.” Sources: https://www.fraenkische.com/en/faq/electrical-systems ### [Conduit installation in explosion hazard area, what conduit can be used here?](https://directory.readyscan.ai/entities/frankische-rohrwerke-q64485067#company-answer-content-native-digital-agencies-1bd6d24d0ef0b210-a-60449bf671ce26515acd) “All steel and metal conduits - these, however, must be included in the equipotential bonding.
