District heating and district cooling pipes - Bonded pipe systems for directly buried hot and cold water networks - Part 2: Factory made steel service valve assembly for steel service pipes, polyurethane thermal insulation and a casing of polyethylene
Abstract
This document specifies requirements for factory made thermally insulated bonded steel service valve assemblies for filling, draining, venting and operation purposes for directly buried hot and cold water networks in accordance with EN 13941-1, comprising a steel service valve, steel service pipe, polyurethane (PUR) foam thermal insulation and a casing of polyethylene (PE). This document applies of steel service valve assemblies with an internal pressure of maximum 2,5 MPa. The principles of this document can be applied to thermal insulated bonded steel service valve assemblies with internal pressures higher than 2,5 MPa, provided that special attention is paid to the effects of pressure. The steel service valve assembly can also include the following additional elements: measuring wires, spacers, and diffusion barriers.
