| Use advice for data set | Scope: The declaration is for specific product - Preinsulated bonded TwinPipe 2x60.3/200- conti method. The declared product is produced by LOGSTOR Denmark Holding ApS in production plant in Lgstr, Denmark (DK). System boundary: The life cycle assessment addressees the life cycle of the pipe system from cradle to gate with options, modules C1-C4, and module D (A1-A3, C,D and additional modules. The additional modules include A4 and A5). The product stage comprises the modules A1 (raw material procurement), A2 (transport), A3 (production), A4 (delivery), A5 (assembly), C1 (dismantling), C2 (transport), C3 (waste treatment), C4 (disposal) and D (recycling potential) in accordance with /EN15804+A2/ including the provision of all materials, products and energy. Production stage (A1-A3): Extraction, processing and transport of raw materials (including steel pipes, PU foam, PE film, copper wire) used for the production of the pipe system. Delivery (A4): Transport of the the pipe system to the construction site by truck (assuming e.g. 100 km as a base value or an averaged distance) Installation (A5): Manual installation of the the pipe system and the offcuts or auxiliary materials during installation are not considered. Deconstruction (C1): Manual removal of the pipe system Transport (C2): Transport of the dismantled pipe system for waste management by truck transport (50 km). Waste treatment (C3): Waste treatment of the pipe system: 100% material recycling for the metal components of the pipe system (steel, copper and/or aluminium pipes) and 100% thermal utilisation of the plastic components of the pipe system in a waste incineration plant (MVA) with an R1 value > 0.6 with declaration of recovery potential in D from Energy substitution. Disposal (C4): no further expenses due to Landfill/disposal. Module D: Energy substitution and benefits from A5 and C3 are declared in module D. | ||

| General comment on data set | Preinsulated bonded TwinPipe 2 x 60.3/ 200 – conti method – is a preinsulated pipe with 2 media steel pipes diam. 60.3 mm and casing pipe (200 mm). Length of product – 12 meters. Conti TwinPipe (axial) is a complete transmission and distribution system for district heating. Using TwinPipe for district heating pipelines systems can lead to significant savings in terms of heat loss and CO2 emissions, as well as investment and operating costs. In the axial conti process pipes are made by casting the insulation onto the service pipes in a moving mould, after which the casing is extruded onto the insulation. The production takes place in continuous process. An effective diffusion barrier foil, preventing diffusion of insulating gases is embedded between the insulation and the casing. Consequently, continuously produced pipes with diffusion barrier foil do not age in relation to heat loss property. | ||

| Technology description including background system | LOGSTOR TwinPipe pre-insulated pipes are a pipe-in-pipe assembly with a composite structure consisting of: - two steel service pipes or steel compensator, - thermal insulation made of rigid polyurethane foam (PUR) with a porous structure, light yellow in color, foamed with the use of cyclopentane, - outer jacket made of polyethylene (PE-HD), made directly in the continuous production process of pre-insulated pipes or made of a pipe produced in a separate production process, black (with or without a diffusion barrier layer). "Axial conti" method - in which thermal insulation of the pipe is made in one process line (by applying successive layers of mixed foam components to the carrier pipe placed in a movable form) and the protective coat is pressed onto the ready insulation; the method is used for the production of LOGSTOR pipes with a casing diameter of DC 90 ÷ 315 mm; Technical data: Axial continuous production method: Straight TwinPipe Diameter of carrier pipe: 60.3 mmSteel carrier pipe Insulation serie 1 With a diffusion barrier which ensures that the insulation property is kept constant over life time Lambda value 50: 0.023 W/mK Used materials: Steel pipe: Longitudinally or spiral welded P235GH according to EN10217-2 Insulation: Polyurethane foam; Properties: Minimum as required in EN 253 Blowing agent: Cyclopentane Outer casing: Polyethylene, HDPE, bimodal (Minimum PE 80, ISO 12162); Properties: Minimum as required in EN 253. All parts are fully weldable within the melt flow index: MFR variation ≤ 0.5 g/10 min. Thermal stability: Oxydation induction time (OIT): > 20 min. at 210° C. Surveillance system: Wires: 1.5 mm2 copper wires (one is tinned). The embedded copper wires are the backbone of the electronic surveillance systems which is available for most of our pipe systems. | ||
