District cooling pipes - Bonded single pipe systems for directly buried cold water networks - Part 2: Factory made fitting assemblies of steel or plastic service pipe, polyurethane thermal insulation and a casing of polyethylene
Preview
Summary
This document 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.
This document covers the following fitting assemblies: bend, tee, reducer, cap and anchor.
This document 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.
The design is based on an expected service life with continuous operation of a minimum 50 years.
NOTE An expected service life of 50 years presupposes that treated water is used.
