What is BS EN 17414‑1 about?
BS EN 17414‑1 is the first part of the BS EN 17414 series of documents that specifies requirements and test methods for factory-made thermally insulated flexible pipe-in-pipe assemblies for directly buried district cooling distribution systems, comprising a service pipe and a casing of polyethylene. The pipe assembly can also include the following additional elements: measuring wires, spacers, and diffusion barriers.
The design is based on an expected service life with continuous operation of a minimum 50 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in EN 17414-2 and EN 17414-3.
NOTE: BS EN 17414‑1 applies only to insulated pipe assemblies, for continuous operation with water at various temperatures (1 to 30) °C and a maximum operation pressure of 25 bar dependent on material specified.
Who is BS EN 17414‑1 for?
BS EN 17414‑1 on requirements and test methods of the flexible pipe system is useful for:
- Manufacturers of steel or plastic service pipes
- Manufacturers and suppliers of polyurethane thermal insulation
- Air- conditioners, fans manufacturing industries
Why should you use BS EN 17414‑1?
District cooling is an emerging urban utility service involving the centralised production of chilled water that is piped to commercial buildings for air-conditioning.
BS EN 17414‑1 gives the properties of thermal insulation and bending radius of the pipe assembly and provides test methods to check the resistance to an external load while casing pipe assemblies and joints.
BS EN 17414‑1 provides the test procedure to ensure the thermal conductivity of factory-made pipe assemblies in accordance with temperature.
Overall, BS EN 17414‑1 let you manufacture the district cooling pipe to reduce strain on the electric grid caused by increasing demands for cooling systems. Also, let you build an efficient and the necessary requirements for the waste management system and recycling of materials used for district cooling pipes.
