API Standard 617

geared centrifugal and axial compressors, in addition to the general requirements specified in API 617, Part 1. These machines do not have gears integral with their casing but can have external gears. Part 3—Integrally Geared Centrifugal Compressors, specifies integrally geared centrifugal compressors in conjunction with API 617, Part 1.
