Requirements for designing pulsation suppression devices (acoustic bottles) to prevent mechanical fatigue in the piping.
Highly customized, foundation-mounted, block-by-block engineering setups.
API 618 compression systems are typically developed directly by major manufacturers (such as GE) and represent specialized technology for refinery and petrochemical environments. In contrast, API 11P units are available through a network of authorized packagers and distributors, often as part of complete, cost-effective compression packages that include direct-coupled drivers for seamless integration into existing infrastructure.
Because packaged compressors are modular, the skid acts as the foundation. API 11P outlines how the skid must handle the dynamic forces generated by the reciprocating mass of the compressor. It specifies anchor bolt locations, environmental load calculations (such as wind and seismic action), and continuous welding requirements to avoid structural resonance. 2. Pulsation and Vibration Mitigation
The API 11P PDF serves as a checklist and design roadmap for packagers and end-users. It outlines strict guidelines across several engineering disciplines. 1. Structural Skid Design api 11p pdf
This specification establishes the minimum requirements for packaged, skid-mounted, reciprocating compressors used in oil and gas production GlobalSpec . Unlike the more stringent
, which governs more complex, heavy-duty "special purpose" reciprocating compressors used in refineries and petrochemical plants. Key Technical Sections

Detailed layouts for frame and cylinder lubrication to prevent premature mechanical wear. 2. Packaging and Skid Design
Companies like Burckhardt Compression offer fully balanced reciprocating compressor systems specifically compliant with ISO 13631 (API 11P) for upstream, midstream, and downstream applications. These high-speed compressors feature lubricated and non-lubricated designs, are driven by electric motors or gas engines, and are available in frames with 2, 4, or 6 cranks delivering power up to 7,500 kW. Such systems are the preferred solution for a wide range of oil and gas applications requiring high-speed reciprocating compression.
Official versions of the API 11P standard are available through authorized distributors: The American Petroleum Institute (API) and downstream applications.
: The 3rd Edition includes updated Data Sheets specifically tailored for procurement and initial purchase.
: Horizontal, separable, balanced-opposed units suitable for direct coupling to prime movers.
Concurrently, API began shifting the industry toward using ( Reciprocating Compressors for Petroleum, Chemical, and Gas Industry Services ) for critical process applications, while relying on ISO 13631 or updated regional adoptions for high-speed packaged units.
The oil and gas industry relies heavily on reciprocating compressors for gas lift, pipeline transmission, gathering, and injection. To ensure these systems operate safely and reliably, the American Petroleum Institute established .
: Discharge temperature is typically limited to 350°F (176.7°C) .
Earlier editions of API 11P include:
