Standards related to API compressors

Thread Content

A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. In the production of the oil, petrochemical, and natural gas industries, compressors are widely used as devices for increasing gas pressure. The American Petroleum Institute (API) has issued a series of standards (Standard, Std), recommended practices (Recommended Practice, RP), and technical reports (Technical Report, TR) related to compressors for use in the industry; these are listed below for reference. (Note: The image is from the Internet; it shows a Siemens compressor.) API Std 611-2022 General-Purpose Steam Turbines for Petroleum, Chemical and Gas Industry Services / General-purpose steam turbines for use in the petroleum, chemical, and gas industries, 6th Edition API Std 612-2020 Petroleum, Petrochemical and Natural Gas Industries – Steam Turbines – Special-Purpose Applications / Steam turbines for special purposes in the petroleum, chemical, and natural gas industries, 8th Edition API Std 613-2021 Special Purpose Gear Units for Petroleum, Chemical and Gas Industry Services / Gear units for special purposes in the petroleum, chemical, and gas industries, 6th Edition API Std 614-2022 Lubrication, Shaft-Sealing and Control-Oil Systems and Accessories / Lubrication, shaft sealing, control oil systems, and related accessories, 6th Edition API Std 616-2022 Gas Turbines for the Petroleum, Chemical and Gas Industry Services / Gas turbines for use in the petroleum, chemical, and gas industries, 6th Edition API Std 617-2022 Axial and Centrifugal Compressors and Expander-Compressors / Axial and centrifugal compressors as well as expanders, 9th Edition API Std 618-2007(R2017) Reciprocating Compressors for Petroleum, Chemical and Gas Industry Services / Reciprocating compressors for use in the petroleum, chemical, and gas industries, 5th Edition API Std 619-2010 Rotary-Type Positive Displacement Compressors for Petroleum, Petrochemical and Natural Gas Industries / Rotary positive displacement compressors for use in the petroleum, chemical, and natural gas industries, 5th Edition API Std 670-2014(R2022) Machinery Protection Systems / Machinery protection systems, 5th Edition API Std 671-2020 Special Purpose Couplings for Petroleum, Chemical, and Gas Industry Services / Special-purpose couplings for use in the petroleum, chemical, and gas industries, 5th Edition API Std 672-2019 Packaged, Integrally Geared Centrifugal Air Compressors for Petroleum, Chemical and Gas Industry Services / Integrated gear-driven centrifugal air compressors for use in the petroleum, chemical, and gas industries, 5th Edition API Std 673-2014 Centrifugal Fans for Petroleum, Chemical, and Gas Industry Services / Centrifugal fans for use in the petroleum, chemical, and gas industries, 3rd Edition / Note: The main function of fans is to transport gases, rather than to increase gas pressure; generally, when the outlet pressure exceeds 350000 Pa, it is considered a compressor. API Std 677-2021 General-Purpose, Extruder, and Epicyclic Gear Units for Petroleum, Chemical and Gas Industry Services / General-purpose die gears and epicyclic gear units for use in the petroleum, chemical, and gas industries, 4th Edition API Std 681-2021 Liquid Ring Compressors and Vacuum Pumps in Petroleum, Chemical and Gas Industry Services / Liquid ring compressors and vacuum pumps for use in the petroleum, chemical, and gas industries, 2nd Edition API RP 684-2005(R2010) API Standard Paragraphs Rotordynamic Tutorial: Lateral Critical Speeds, Unbalance Response, Stability, Train Torsionals and Rotor Balancing / API standard tutorial on rotordynamics: lateral critical speeds, unbalance response, stability, torsional effects, and rotor balancing, 2nd Edition API TR 684-1-2019 API Standard Paragraphs Rotordynamic Tutorial: Lateral Critical Speeds, Unbalance Response, Stability, Train Torsionals and Rotor Balancing / API standard tutorial on rotordynamics: lateral critical speeds, unbalance response, stability, torsional effects, and rotor balancing, 1st Edition API RP 686-2009(R2014) Recommended Practice for Machinery Installation and Installation Design / Recommended practices for machinery installation and design, 2nd Edition API RP 687-2023 Special-Purpose Rotating Equipment Repairs / Repair of rotating equipment for special purposes, 2nd Edition API Std 688-2023 Pulsation and Vibration Control for Positive Displacement Machinery Systems for Petroleum, Chemical and Natural Gas Industry Services / Control of pulsation and vibration in positive displacement machinery systems used in the petroleum, chemical, and natural gas industries, 2nd Edition API RP 691-2017 Risk-Based Machinery Management / Machinery management based on risk assessment, 1st Edition API Std 692-2018 Dry Gas Sealing Systems for Axial, Centrifugal, and Rotary Screw Compressors and Expanders / Dry gas sealing systems for axial, centrifugal, and rotary screw compressors and expanders, 1st Edition Note: The years in parentheses indicate the years in which the standards were reaffirmed.
