Compressor Selection Maps: reciprocating
Compressor selection maps per API 617/618/619 — operating envelopes, polytropic efficiency ranges, specific power, surge and turndown limits, molecular weight suitability, discharge temperature limits, capacity control methods, pulsation requirements, lubrication/maintenance intervals, and selection criteria for centrifugal, reciprocating, screw, scroll, diaphragm, and axial compressors
| compressor type | record id | api standard | notes | parameter category | size class | typical applications |
|---|---|---|---|---|---|---|
| reciprocating | api_class_envelope | API 618 | API 618 applies to compressors with rod diameter > 65 mm (2.5 in) in petroleum, chemical, gas service; excludes fire-suppression, refrigeration under API 600, and internal combustion engines; Design Approach 1/2/3 based on HP x RPM product | api_class_envelope | all | Reciprocating compressors in petroleum chemical and gas service |
