ISO 10440-1:2007

Overview

ISO 10440-1:2007 - Petroleum, petrochemical and natural gas industries - Rotary-type positive-displacement compressors - Part 1: Process compressors - is an ISO standard that specifies requirements for dry and oil-flooded helical‑lobe rotary compressors used for vacuum, pressure, or both in process services. Published as the second edition (2007), it replaces ISO 10440-1:2000 and targets special-purpose process compressors in the petroleum, petrochemical and natural‑gas sectors. The published package includes a PDF of the standard and electronic data sheets available in SI and USC units.

Key Topics

ISO 10440-1:2007 focuses on the unique characteristics and requirements of rotary‑type positive‑displacement (helical‑lobe) compressors in process applications. Key topics and scope elements include:

• Compressor types covered: Dry and oil‑flooded helical‑lobe rotary compressors.
• Service conditions: Use for vacuum, pressure, or combined vacuum/pressure process duties.
• Application scope: Designed for special‑purpose industrial process compressors in petroleum, petrochemical, and natural gas facilities.
• Exclusions: Not applicable to general‑purpose air compressors, liquid‑ring compressors, or vane‑type compressors.
• Deliverables: Standard text plus electronic data sheets (SI and USC) to support specification and procurement.

(Note: ISO 10440-1:2007 sets requirements; for specific design, testing or installation procedures users should consult the full standard document.)

Applications

This standard is relevant wherever helical‑lobe rotary compressors are used in process plants, including:

• Refineries and petrochemical complexes - for gas compression, vapor recovery and process cooling loops.
• Natural gas processing and transmission - for lean gas handling, vapor recovery and system depressurization.
• Special‑purpose process equipment - custom compressor packages where standard air compressors are not suitable.

Using ISO 10440-1 helps ensure compressors meet industry expectations for suitability in process services, aiding safer procurement and consistent performance.

Who uses this standard

Typical users include:

• Process and rotating‑equipment engineers specifying compressors for petroleum, petrochemical and gas plants.
• OEMs and compressor manufacturers designing or certifying helical‑lobe rotary units.
• Procurement teams preparing technical specifications and data sheets.
• Inspection, maintenance and compliance personnel verifying equipment suitability for process service.
