SIST EN ISO 10439-2:2015 PDF

Overview

SIST EN ISO 10439-2:2015 sets out the minimum requirements and key recommendations for non-integrally geared centrifugal and axial compressors used in petroleum, petrochemical, and natural gas industries. The standard focuses on compressors and expander-compressors intended for demanding applications where robust operation, process integrity, and safety are essential. These machines handle process gases or air and are distinguished by the absence of gears integral with the compression casing, though they may utilize external gears.

By providing detailed guidance on compressor design, materials, inspection, testing, and ancillary equipment, this international standard ensures reliability, efficiency, and safety in critical process environments.

Key Topics

• Compressor Types Covered:

  • Non-integrally geared centrifugal compressors
  • Non-integrally geared axial compressors
  • Expander-compressors (excluding integrally geared units)

• Scope and Application:

  • Applicable to single-shaft and process compressors for special purpose applications
  • Machines not fitted with integral gearing in their casings

• Design and Construction:

  • Requirements for pressure-containing casings, material selection, and casing support
  • Rotor and shaft construction, including balancing and stress considerations
  • Implementation of guide vanes, stators, internal joints, and seal components

• Safety and Integrity:

  • Statutory and regulatory compliance
  • Design considerations for hydrogen and other hazardous or flammable process gases
  • Inspection, testing, and preparation stipulations to ensure process safety

• Accessories and Ancillaries:

  • Lubrication and sealing systems
  • Controls and instrumentation
  • Couplings, guards, and mounting solutions

• Documentation and Data:

  • Requirements for technical datasheets and vendor documentation
  • Guidelines for supplier data, drawings, and reporting

Applications

SIST EN ISO 10439-2:2015 is essential for organizations designing, specifying, operating, or maintaining centrifugal and axial compressors in the following sectors:

• Petroleum Refining – Process gas handling, hydrogen recycling, air compression for refining operations
• Petrochemical Production – Gas compression for synthesis, recirculation, and product processing
• Natural Gas Processing and Transmission – Pipeline gas compression, gas treatment plants, underground storage facilities
• Industrial Gas Applications – Large-scale air separation, fertilizer plants, and syngas production

Key benefits of implementing this standard include:

• Enhanced operational safety through strict design and testing protocols
• Improved process reliability due to standardized maintenance and inspection recommendations
• Facilitated procurement and commissioning by ensuring compatibility and clarity in technical requirements
