BS EN 253:2003+A2:2006 District heating pipes — Preinsulated bonded pipe systems for directly buried hot water networks — Pipe assembly of steel service pipe, polyurethane thermal insulation and outer casing of polyethylene
This European Standard specifies requirements and test methods for straight lengths of prefabricated thermally
insulated pipe-in-pipe assemblies for directly buried hot water networks, comprising a steel service pipe from DN 20
to DN 1200, rigid polyurethane foam insulation and an outer casing of polyethylene.
This standard applies only to insulated pipe assemblies, for continuous operation with hot water at various
temperatures up to 120 °C and occasionally with a peak temperature up to 140 °C.
The estimation of expected thermal life with continuous operation at various temperatures is outlined in annex B.
