Full title and description

ANSI/API STD 619:2010 — Rotary-Type Positive-Displacement Compressors for Petroleum, Petrochemical and Natural Gas Industries. Fifth edition (December 2010). This standard specifies minimum requirements for dry and oil‑flooded helical‑lobe rotary (positive‑displacement) compressors intended for process service in petroleum, petrochemical and natural gas industries; it is the API adoption of the ISO 10440‑1 technical content for such compressors.

Abstract

API STD 619:2010 defines design, materials, manufacturing, testing and documentation requirements for helical‑lobe rotary compressors used for vacuum and/or pressure duties in process applications. It excludes general‑purpose air compressors, liquid‑ring compressors and vane‑type compressors and aligns with ISO 10440‑1:2007 requirements for process compressors.

Scope

Specifies requirements for dry and oil‑flooded helical‑lobe rotary compressors used in process service within the petroleum, petrochemical and natural gas industries (vacuum and/or pressure duties). Intended for special‑purpose/process compressors; not applicable to general‑purpose air compressors, liquid‑ring machines or vane‑type compressors. The API edition is the national adoption of the ISO 10440‑1 technical requirements for process rotary compressors.

Key topics and requirements

• Design requirements for helical‑lobe rotary positive‑displacement compressors (materials, clearances, seals and bearings).
• Performance and capacity definitions, allowable operating conditions and limits.
• Lubrication and oil‑flooded vs. dry design considerations.
• Testing, inspection and acceptance criteria (factory tests, performance tests and documentation requirements).
• Mechanical integrity, safety and recommended data‑sheet items for purchaser/supplier exchange.
• Exclusions and application boundaries (what compressor types and services are not covered).

These topics reflect the standard's focus on minimum acceptable engineering, testing and documentation practices for process rotary compressors.

Typical use and users

Used by OEM compressor manufacturers, process engineers, rotating‑equipment engineers, EPC contractors, procurement/specification teams and maintenance/inspection groups specifying, designing, supplying or operating rotary positive‑displacement compressors in refinery, petrochemical and gas processing facilities.

Related standards

Closely related to ISO 10440‑1:2007 (rotary‑type positive‑displacement compressors — Part 1: process compressors) which forms the technical basis; see also ISO 10440‑2 (packaged oil‑free air compressors) and other API standards for positive‑displacement and rotating equipment (for example API standards covering reciprocating and centrifugal compressors and complementary machinery specifications).

FAQ

Q: What is this standard?

A: ANSI/API STD 619:2010 is the API standard that defines minimum requirements for rotary‑type positive‑displacement (helical‑lobe) compressors used in petroleum, petrochemical and natural gas process services (Fifth edition, 2010).

Q: What does it cover?

A: It covers design, materials, testing, performance definitions, documentation and acceptance criteria for dry and oil‑flooded helical‑lobe rotary compressors in process applications; it excludes general‑purpose air compressors, liquid‑ring compressors and vane‑type compressors.

Q: Who typically uses it?

A: OEMs, process and rotating‑equipment engineers, procurement/specification teams, EPC contractors and maintenance personnel involved with specifying, procuring, installing or maintaining process rotary compressors.

Q: Is it current or superseded?

A: This is the Fifth Edition published in December 2010. Publisher records list this edition as the API adoption of ISO 10440‑1; registry/listings indicate the 2010 edition has been reaffirmed in subsequent years (publisher listings note reaffirmation activity). Users should verify with API for the absolute latest status or any amendments before procurement or design work.

Q: Is it part of a series?

A: Yes — it corresponds to the ISO 10440 series (Part 1 addresses process compressors). A Part 2 (ISO 10440‑2) covers packaged oil‑free air compressors. API STD 619 is the API adoption addressing the rotary positive‑displacement process compressor topic.

Q: What are the key keywords?

A: rotary compressor; helical‑lobe; positive‑displacement; oil‑flooded; dry compressor; process compressor; API 619; ISO 10440‑1; petroleum; petrochemical; natural gas.
