District heating pipes - Bonded single pipe systems for directly buried hot water networks - Factory made fitting assemblies of steel service pipes, polyurethane thermal insulation and a casing of polyethylene
Abstract
This document specifies requirements and test methods for factory made thermally insulated bonded fitting assemblies for hot water networks in accordance with EN 13941-1, comprising a steel service pipe, in most cases a steel fitting, polyurethane (PUR) foam thermal insulation and a casing of polyethylene. The fitting assembly can also include the following additional elements: measuring wires, spacers and diffusion barriers. This document specifies the characteristics of the following fitting assemblies: - bends, T-pieces, and reducers. This document applies to fitting assemblies with a design pressure of at least 1,6 MPa.
