What is BS EN 17415‑2 about?
BS EN 17415‑2 is the second part of the multi-series of European standard EN 17415 on ‘District cooling pipes – Bonded single pipe systems for directly buried cold water networks.’
BS EN 17415-2 specifies requirements, design and test methods for factory-made thermally insulated bonded fitting assemblies for directly buried district cooling distribution systems, comprising a service fitting from DN 15 to DN 1200, rigid polyurethane foam insulation and a casing of polyethylene.
The fitting 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.
NOTE: BS EN 17415‑2 applies only to insulated fitting assemblies, for continuous operation with water at various temperatures (1 to 30) °C and a maximum operation pressure of 25 bar.
NOTE: BS EN 17415‑2 covers the following fitting assemblies: bend, tee, reducer, cap and anchor.
Who is BS EN 17415‑2 for?
BS EN 17415‑2 on district cooling pipes is relevant to:
- Manufacturers of fitting assemblies of steel or plastic service pipes
- Manufacturers and suppliers of polyurethane thermal insulation
- Air- conditioner, fans manufacturers
Why should you use BS EN 17415‑2?
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 17415‑2 provides guidelines for inspection of factory-made fitting assemblies and gives requirements of polyethylene casing welding to ensure that the welds are leak-tight and the polyurethane foam insulation to determine the compressive strength.
Overall, the test methods for steel parts inspection given in BS EN 17415‑2 helps maintain stringent quality control of the plastics service pipe fittings in accordance with temperature and pressure. BS EN 17415‑2 also enables an efficient waste management system for district cooling pipes.
