Api 11p Pdf -
API 11P is strict regarding cylinder design:
A common confusion is how API 11P relates to API 618 and API 619.
| Standard | Title | Key Focus | | --- | --- | --- | | API 11P | Packaged Reciprocating Compressors for Oil & Gas Production | Small-to-mid sized units, skid-mounted, production service (lower speeds, higher pressures) | | API 618 | Reciprocating Compressors for Refinery Service | Large, high-speed or slow-speed units, refinery or chemical plants, very strict pulsation limits | | API 619 | Rotary-type Positive Displacement Compressors | Not reciprocating; covers rotary screws and lobes | api 11p pdf
Verdict: If you are buying a small gas compressor for a well pad or gas lift, you likely need API 11P. For a multi-stage refinery hydrogen compressor, you need API 618.
| Criteria | API 11P | API 618 | |----------|---------|---------| | Application | Field production, wellhead, low-to-mid pressure | Refinery, gas plant, continuous heavy duty | | Packaging | Fully skid-mounted, factory tested as unit | Often field-erected, larger frames | | Speed | Typically 600–1800 rpm | Typically 200–600 rpm | | Piston speed | Up to 5 m/s (1000 fpm) | Typically 3.5–4.5 m/s | | Lube system | Often splash or force-feed | Fully pressurized forced lube | API 11P is strict regarding cylinder design: A
If your project is vapor recovery, flare gas boosting, or wellhead gas lift – API 11P is correct.
