Rohrleitungen in Verdichter- und Expansionsanlagen
Brief description
This technical rule applies to the planning, manufacture, installation and maintenance of pipelines for gases in accordance with DVGW Code of Practice G 260 in systems in accordance with DVGW Codes of Practice G 487 and G 497, in accordance with the examples listed in DIN EN 12583 Section 1. In addition to the requirements from these regulations, connecting pipes, including their integration into the gas transport pipeline, can also be part of the system, provided they are located on the station site or in the immediate vicinity of the station and are functionally part of the system. Pipelines within the meaning of this technical rule are all pipelines and component groups in accordance with DIN 30690-1 between or at direct connections of working machines and compressors, apparatus, containers, fittings, control and safety devices as well as measuring and other functional devices. This technical rule specifies the requirements to be observed in accordance with the Ordinance on High-Pressure Gas Pipelines (GasHDrLtgV) Section 3 (1) to prevent hazards that may arise for employees or third parties from pipelines in compressor and expansion systems. For pipelines in compressor and expansion systems that are subject to mining law (including compressor systems in underground gas storage facilities), this technical rule applies mutatis mutandis.
