| Use advice for data set | Scope: The EPD applies to the RAUTITAN flex pipe with the pipe sizes 12 x 1,7 mm 16 x 2,2 mm 20 x 2,8 mm 25 x 3,5 mm 32 x 4,4 mm 40 x 5,5 mm 50 x 6,9 mm 63 x 8,6 mmmanufactured in plants of REHAU Industries SE & Co. KG in Triptis, Viechtach (both D) and Klaipeda (LT). This is an average EPD based on an average generic product variant. System boundary: Consideration of the entire product life cycle if the utilisation phase is not taken into account, see figure. Type of EPD: Cradle to factory gate with options (Modules A4, A5, C and D). The following flow diagram shows the system limits when balancing RAUTITAN flex. The following is a detailed list of the life cycle stages and process modules taken into account for the production of the pipe: A1 – A3 Production phase Production of raw materials, ancillary materials and consumables, including transport to the respective plant Production of the master batch, including transport Production of the sealing ring at the supplier, including transport Production of packaging materials for the end product Energy supply for production Production and packaging of the pipes Production of packaging materials for raw materials, including transport for recycling with subsequent utilisation Transport of reusable packaging for raw materials Transport of production waste and utilisation thereof A4 and A5 construction phase Transport of the pipe to the construction site Transport of the pipe packaging for recycling with subsequent recycling Energy supply for the installation (e.g. electrical tools) Production of ancillary materials (cement) Transport and utilisation of offcuts Flushing the installed pipe with tap water C1 – C4 Disposal Three 100% disposal scenarios are assumed: EoL scenario 1 (thermal utilisation): Dismantling the pipe, including transport to the recycling site with energy recovery (Modules C3/1 and D/1). EoL scenario 2 (recycling): Dismantling the pipe, including transport to the recycling site with material recycling, i.e. grinding into filler (Modules C3/2 and D/2). EoL scenario 3 (landfill): Dismantling the pipe, including transport to the disposal site. Disposal takes place at a local landfill (Modules C4/3 and D/3). D Reuse, recovery and/or recycling potentials Reuse, recovery and/or recycling potentials are available in the disposal scenarios, as the pipe systems are recycled here for energy or materials, from which energy or secondary materials are recovered that can be used outside the system boundary. Energy recovered from the incineration of packaging waste in Module A5 is not taken into account. In EoL scenarios 1 and 2, on the other hand, there are effects from the recovery of energy from the incineration of waste. In EoL scenario 2, no advantages from the subsequent utilisation of secondary material as filler are taken into account. | ||
| Technical purpose of product or process | The pipes in the RAUTITAN flex product group can be used universally for drinking water and heating installations in building construction in accordance with EN ISO 15875. The pipes are also oxygen-tight in accordance with DIN 4726. | ||

| General comment on data set | The plastic pipe for hot and cold water installations in buildings covered by the study is a three-layer pipe consisting of a pressure-stable cross-linked PE XaInliner, a grey-coloured bonding agent and an oxygen barrier layer as an outer shell made of EVOH. The pipe can be used universally for drinking water and heating installations. The trade name is RAUTITAN flex. | ||

| Technology description including background system | The pipes are produced by REHAU Industries SE & Co. KG in European plants. In the pipe manufacturing process, the PE is peroxide cross-linked under high pressure to form PE-Xa and then coated with an adhesion promoter and outer layer. Technical data: The values given in the following table apply to the product RAUTITAN flex in all pipe sizes. Declared unit: The declared unit is defined as 1 kg of pipe. This corresponds to 0.99 kg of installed pipe (see scenario information on Module A5 in section 4). An average product of the RAUTITAN flex pipe was analysed. It is based on the production volumes for 2022 and therefore covers all product variants (listed in 2.4 Delivery status). The mass reference differs depending on the pipe size. | ||
