Description
This dataset represents the average level of the on-site construction and installation and the decommissioning and dismantling process of heat supply pipe networks in China. Its data are obtained by weighted aggregation of the hot water and steam heat supply pipe datasets, with the weights based on the national heat supply proportions of hot water and steam. The technical service life is 30 years. The data are mainly sourced from official statistics.
Activity Description
The system boundary involves raw material preparation, on-site construction and installation, and decommissioning and dismantling stages, excluding the operation and maintenance stage.
Process Description
The heat supply network is a pipeline system that transports and distributes heating medium from heat sources to heat users. Depending on the type of heating medium, it can be divided into hot water heating networks and steam heating networks.

Technology comment
The on-site construction and installation of the heating pipe network is divided into civil engineering and pipeline installation engineering, taking into account key facilities and equipment including pipelines, insulation pipes, corrugated compensators, etc., and the technical service life is 30 years. A unified assumption is adopted for the decommissioning and dismantling stage, that is, it is assumed that the recovery rate of metal materials, wood, and cables is 90%, plastics and rubber products are disposed of as non-recyclable materials, and the remaining waste is disposed of as inert waste.
