This Standard supersedes IGEM/UP/6 Edition 2 Communication 1741, which is obsolete.
IGEM/UP/6 Edition 3 covers the application of new positive displacement reciprocating compressors, screw compressors, slide vane compressors and centrifugal compressors to downstream natural gas installation pipework systems. Positive displacement compressors installed on industrial and commercial premises, within the stated scope for pressure, volume and power input, are also covered, as are the positive displacement compressors used in natural gas vehicle filling stations, where the shaft power input, normally, is in the range 10kW to 100kW. It applies to compressors using natural gas that are installed downstream of a primary meter installation. Specifically, it contains details of:
- Legal considerations such as Gas Safety (Installation and Use) Regulations
- Gas supply
- Metering/compressor effects
- Installation of a compressor, including location and venting
- Operation and maintenance
