1 Scope
This document specifies requirements and test methods for straight lengths of factory made thermally
insulated bonded twin pipe assemblies for directly buried hot water networks in accordance with
EN 13941-1, comprising two steel service pipes, rigid polyurethane foam thermal insulation and one casing
of polyethylene.
The pipe assembly can also include the following additional elements: measuring wires, spacers and
diffusion barriers.
