DANSK DS/EN ISO 10439-2 PDF

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 non-integrally geared centrifugal and axial compressors, in addition to the general requirements specified in ISO 10439-1:-1). These machines do not have gears integral with their casing but can have external gears. NOTE See ISO 10439-3:-1) for integrally geared process compressors, or API 672 for packaged plant instrument air compressors.
