Annotation of standard text ČSN EN 13941-1+A1 (383370):
This document specifies requirements for design, calculation and installation of factory made thermal insulated bonded single and twin pipe systems for buried hot water networks for continuous operation with treated water at various temperatures up to 120 °C and occasionally peak temperatures up to 140 °C for maximum 300 h/a, and maximum internal pressure 2,5 MPa. Flexible pipe systems according to the EN 15632 series are not under the scope of this standard. The standard EN 13941, Design and installation of thermal insulated bonded single and twin pipe systems for directly buried hot water networks consists of two parts: a) EN 13941 1: Design; b) EN 13941 2: Installation. The requirements in this part, EN 13941 1, form a unity with those of EN 13941 2. The principles of the standard may be applied to thermal insulated pipe systems with pressures higher than 2,5 MPa, provided that special attention is paid to the effects of pressure. Adjacent pipes, not buried, but belonging to the network (e.g. pipes in ducts, valve chambers, road crossings above ground etc.) may be designed and installed according to this standard. This document presupposes the use of treated water, which by softening, demineralization, de-aeration, adding of chemicals, or otherwise has been treated to effectively prevent internal corrosion and deposits in the pipes. NOTE - For further information on water qualities to be used in district heating pipe systems see also bibliographic entry [2]. This standard is not applicable for such units as: a) pumps; b) heat exchangers; c) boilers, tanks; d) systems behind domestic substations
