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
N SN EN 253+A1
Annotation
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 15 to DN 1200, rigid polyurethane foam insulation and an outer casing of polyethylene. The pipe assembly may also include the following additional elements: measuring wires, spacers and diffusion barriers.
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.

Этот европейский стандарт определяет требования и методы испытаний в течение прямых продолжительностей сборных тепло сборок изолированной трубы в трубе для непосредственно проложенных под землей сетей горячей воды, включая стальную сервисную трубу от DN 15 до 1200 DN, изоляции жесткого пенополиуретана и внешнего корпуса полиэтилена. Сборка трубы может также включать следующие дополнительные элементы: измерительные проволоки, распорные детали и барьеры диффузии.
