Petroleum, petrochemical and natural gas industries - Axial and centrifugal compressors and expander-compressors - Part 4: Expander-compressors (ISO 10439-4:2015); English version EN ISO 10439-4:2015

Title (German)

Erdöl-, petrochemische und Erdgasindustrie - Axial- und Radialkompressoren und Expanderkompressoren - Teil 4: Expanderkompressoren (ISO 10439-4:2015); Englische Fassung EN ISO 10439-4:2015


This part of ISO 10439 specifies minimum requirements and gives recommendations for axial compressors, single-shaft, and integrally geared process centrifugal compressors and expander-compressors for special purpose applications that handle gas or process air in the petroleum, petrochemical, and natural gas industries. This part of ISO 10439 specifies requirements for expander-compressors, in addition to the general requirements specified in ISO 10439-1:2015. This scope covers only expanders and compressors on a common shaft (expander-compressor). This scope does not apply to expanders with separate output shafts (for example, generator drives). Hot gas expanders over 300 °C (570 °F) are not covered in this part of ISO 10439. Regarding German collaboration at DIN the Working Committee is NA 109-00-01-06 AK "Verfahrenstechnische Anlagen und Ausrüstungen" ("Processing equipment and systems") of Standards Committee Petroleum and Natural Gas Industries (NÖG).
