Description
This dataset represents the average level of the on-site construction, installation and decommissioning/dismantling processes of steam heating pipe networks in China. The dataset is based on the construction of two types of steam heating pipelines, DN200 and DN500, and is obtained by weighted aggregation according to the length proportions of the national primary and secondary heating pipe networks. 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, prefabricated insulated pipes and corrugated compensators, with a technical service life of 25 years. A uniform assumption is adopted for the decommissioning and dismantling stage, namely that the recovery rate of metal materials, wood and cables is 90%, plastics and rubber products are treated as non-recyclable, and the remaining waste is treated as inert waste. The data are mainly derived from official publications of engineering design quotas, and have been screened and standardised, with good representativeness, accuracy and applicability.
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 25 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.
