Overview
EN ISO 10439-3:2015 (ISO 10439-3:2015) defines minimum requirements and recommendations for integrally geared centrifugal compressors used in the petroleum, petrochemical and natural gas industries. Part of the ISO 10439 series, this standard addresses design, materials, testing, inspection and supplier data for integrally geared machines that handle gas or process air in special-purpose applications. It was published in 2015 and is adopted as a European standard (EN ISO 10439-3:2015).
Key topics and technical requirements
The standard covers the principal technical subjects needed to specify, procure, design and verify integrally geared centrifugal compressors. Major topics include:
- Scope and definitions - terminology, units and statutory requirements.
- Basic design and performance - minimum design expectations and responsibilities for supplier and purchaser.
- Materials and casings - material selection, pressure-containing casing requirements, repairs and inspection.
- Rotating elements and dynamics - rotor design, balancing and dynamic behavior.
- Bearings and seals - hydrodynamic radial and thrust bearings, bearing housings and shaft end seals.
- Integral gearing - requirements specific to integrally geared stages and gearbox interfaces.
- Accessories and systems - drivers, couplings, lubrication/sealing systems, controls, piping and guards.
- Inspection and testing - mechanical running tests, leakage tests, optional tests and preparation for shipment.
- Supplier and contract data - vendor data requirements, datasheets and drawings.
- Informative and normative annexes - datasheets, vendor drawing requirements, nomenclature, typical materials, inspector’s checklist, external forces and rating formulae.
Practical applications
This standard is used to ensure safe, reliable and interoperable integrally geared centrifugal compressors across upstream, midstream and downstream installations. Typical applications include:
- Gas boosting and compression trains in natural gas processing and transmission
- Process gas circulation and recycle in petrochemical plants
- Compressor packages for refinery units where multi-stage integrally geared machines are required
- Special-purpose process air or gas handling where compact, multi-stage gearing is preferred
Using ISO 10439-3 helps align design and procurement with recognized minimum safety and performance practices, reducing commercial and technical risk.
Who should use this standard
- Compressor manufacturers and OEMs designing or supplying integrally geared centrifugal compressors
- Engineering procurement and construction (EPC) firms specifying compressor packages
- Plant operations, rotating equipment engineers and inspectors responsible for acceptance testing and maintenance
- Technical purchasers and standards/quality managers in petroleum, petrochemical and gas sectors
