These oxygen-tight composite pipes consist of five layers: the base pipe and outer layer are made of PE-RT, securely encasing the sensitive EVOH oxygen barrier layer. To ensure seamless integration, the layers are bonded with adhesive polymer. The result is a premium, highly flexible pipe with a protected oxygen barrier, guaranteeing a long service life of up to 50 years (warranty included) .  \nPIPE FASTENING  \nPipes and their fastening systems must be secured to maintain their planned horizontal and vertical positions. The required fastening distance depends on the pipe dimensions and fastening systems used. The manufacturer specifies the maximum permissible spacing between fixings. Smaller fixing distances enhance the stability of the pipe positions. Fastening distances may vary depending on the system used.  \nAPPLICATION FIELDS  \nTycroc PERT pipes are primarily designed for floor heating. Additional applications include:  \n▪ Cooling ceilings and floors;  \n▪ Heating ceilings and walls;  \n▪ Radiator connections.  \nBENDING RADIUS  \nThe smallest permissible bending radius rr is five times the pipe diameter. For pipe dimensions of 20 mm or larger, a bending radius of eight times the pipe diameter is recommended. The bending radius is influenced by the ambient or pipe temperature. Colder temperatures increase pipe rigidity, requiring a larger bending radius. The recommended bending radius assumes a pipe temperature of 20°C.  \nOXYGEN TIGHTNESS  \nAccording to DIN 4726 standards, oxygen-tight pipes must meet the following area-related oxygen permeability limits:  \n▪ At 40°C (ISO 10508 Class 4): ≤ 0.32 mg/(m² – d);  \n▪ At 80°C (ISO 10508 Class 5): ≤ 3.60 mg/(m² – d) .  \nTycroc PERT 5-layer pipes significantly exceed these standards due to the use of high-performance EVOH and their advanced 5-layer construction.  \nPIPE CONDITION  \nUpon visual inspection (without magnification), the inner and outer surfaces of Tycroc PERT pipes must be smooth, clean, and free from imperfections such as scoring, cavities, or defects that would prevent compliance with ISO 22391 standards. The material must be free from visible impurities. Minor variations in color are acceptable. Pipe ends must be cut burr-free and perpendicular to the pipe axis.  \nCUTTING, STORAGE AND DECOILING  \nCutting Tycroc PERT pipes is straightforward with the use of professional tools, such as a plastic pipe cutter.  \nTo prevent damage during storage or transport, pipes should be protected from adverse weather conditions using cardboard or black foil. They must not be exposed to direct sunlight.  \nPIPE COUPLINGS  \nAll couplings within the floor construction must be accurately positioned and indicated in the revision drawing. Brass clamp and press connectors are recommended as connection elements. These connectors should be installed following the manufacturer’s instructions and securely fastened to the pipes. System compliance is valid only when certified connectors are used.  \nTycroc PERT 5-layer pipes are rigorously tested and approved as part of a system with corresponding clamp and press connectors, certified by DIN Certco and KIWA/KOMO.  \nARRANGEMENT OF HEATING CIRCUITS  \nThe arrangement of heating circuits depends on the purpose, room shape, and specific details such as floor material, windows, and external or internal walls. The two primary patterns are spiral and serial:  \n▪ Spiral Pattern: This design ensures uniform temperature distribution across the heating surface, as the supply and return pipes are alternately placed side by side.  \n▪ Serial Pattern: In this design, the surface temperature decreases linearly from the start to the end of the circuit. The beginning of the circuit should be positioned near areas with the highest heat loss, such as external walls, windows, or terraces.  \nWhile the choice of the heating circui","cbCaitc3VACSfaTo","https://ap.wps.com/l/cbCaitc3VACSfaTo","pdf",467359,"English","# GENERAL\n## PIPE FASTENING\n## APPLICATION FIELDS\n## BENDING RADIUS\n## OXYGEN TIGHTNESS\n## PIPE CONDITION\n## CUTTING, STORAGE AND DECOILING\n## PIPE COUPLINGS\n## ARRANGEMENT OF HEATING CIRCUITS\n## HEATING PIPE INSTALLATION SYSTEMS","[{\"question\":\"What fastening distances are required for Tycroc PERT pipes?\",\"answer\":\"Pipes and fastening systems must keep planned horizontal and vertical positions.
