This Draft Uganda Standard specifies the classification, general requirements and methods of test for flexible, preinsulated, directly buried district heating pipe systems. Depending on the pipe assembly (see Table 4), this standard can be used for maximum operating temperatures of 95 °C to 140 °C and operating pressures of 6 bars to 25 bars. The pipe systems are designed for a lifetime of 30 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in US 945-2.
NOTE For the transport of other liquids, for example potable water, additional requirements may be applicable.
Flexible tubes, pipes and hoses, and fittings therefor, of plastics, burst pressure >= 27,6 MPa (HS code(s): 391731); Pipeline components and pipelines (ICS code(s): 23.040)
