Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
ISO 10439-2 was prepared by Technical Committee ISO/TC 118, Petroleum and natural gas industries,
Subcommittee SC 1, Axial and centrifugal compressors and Expander-compressors in collaboration with
Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical
and natural gas industries, Subcommittee SC 6, Processing equipment and systems.
This second edition cancels and replaces the first edition (ISO 10439:2002), which has been technically
revised and split into four (4) parts.
ISO 10439 consists of the following parts, under the general title Axial and centrifugal compressors and
expander-compressors for special purpose applications handling gas of process air for petroleum,
petrochemical and natural gas industries:
Part 1: General requirements
Part 2: Non-integrally geared centrifugal and axial compressors
Part 3: Integrally geared centrifugal compressors
Part 4: Expander-compressors

Introduction
th
This International Standard is based on the 7 edition of the American Petroleum Institute standard API 617.
Users of this International Standard should be aware that further or differing requirements may be needed for
individual applications. This International Standard is not intended to inhibit a vendor from offering, or the
purchaser from accepting alternative equipment or engineering solutions for the individual application. This
may be particularly appropriate where there is innovative or developing technology. Where an alternative is
offered, the vendor should identify any variations from this International Standard and provide details.
A Bullet (•) at the beginning of a clause or subclause indicates that either a decision is required or further
information is to be provided by the purchaser. This information should be indicated on data sheets or stated
in the enquiry or purchase order (see examples in ISO 10439-2 Annex A, ISO 10439-3 Annex A and
ISO 10439-4 Annex A).
In this International Standard, where practical, US Customary units are included in parentheses for
information.

Part 2:
Non-integrally geared centrifugal and axial compressors
1 Scope
This International standard specifies minimum requirements and gives recommendations for axial
compressors, single-shaft and integrally geared process centrifugal compressors and expander-compressors
for special purpose applications that handle gas or process air in the petroleum, petrochemical and natural
gas industries. This part of ISO 10439 specifies requirements for non-integrally geared centrifugal and axial
compressors, in addition to the general requirements specified in ISO 10439-1. These machines do not have
gears integral with their casing but can have external gears.
NOTE See ISO 10439-3 for integrally geared process compressors, or API Std 672 for packaged plant instrument air
compressors.
2 Normative references

The unit responsibilities of ISO 10439-1 shall apply.
4.4 Basic Design
4.4.1 Performance
4.4.1.1 The sectional head-capacity characteristic curve shall rise continuously from the rated point to
predicted surge. The compressor, without the use of a bypass, shall be suitable for continuous operation at
any capacity at least 10 percent greater than the predicted surge capacity shown in the proposal.
4.4.1.2 The vendor shall provide an overload limit for axial compressors to avoid damaging blade
stresses.
4.5 Materials
Materials shall be in accordance with 4.5 of ISO 10439-1.
NOTE Refer to Annex D for typical materials.
4.6 Casings
Casings shall be in accordance with 4.6 of ISO 10439-1 and 4.6.1 through 4.6.6, as follows.
4.6.1 Pressure-containing Casings
4.6.1.1 The purchaser will specify the relief valve set pressure. The maximum allowable working pressure
of the casing shall be at least equal to the specified relief valve set pressure.
4.6.1.1.1 When a relief valve set pressure is not specified, the maximum allowable working pressure shall
be at least 125 percent of the maximum specified discharge pressure (gauge). System protection shall be
furnished by the purchaser.
4.6.1.2 Casings designed for more than one maximum allowable pressure level (split pressure-level
casings) are permitted only in process air service with an atmospheric pressure inlet. Split pressure-level
casings are not permitted in other services unless specifically approved by the purchaser. If approved, the
vendor shall define the physical limits and the maximum allowable working pressure of each section of the
casing.
4.6.1.3 Unless otherwise specified, casings shall be radially split when the partial pressure of hydrogen
(at maximum allowable working pressure) exceeds 1380 kPa gauge (200 psi gauge). The partial pressure of
hydrogen shall be calculated by multiplying the highest specified mole (volume) percent of hydrogen by the
maximum allowable working pressure.
4.6.1.4 Each axially split casing shall be sufficiently rigid to allow removal and replacement of its upper
half without disturbing rotor-to-casing running clearances and bearing alignment.

joint may be used with purchaser’s approval.
4.6.1.6 Radially split casings normally use “O” rings, gaskets or other sealing devices between the end
head(s) and cylinder. These devices shall be confined in machined grooves, and they shall be made of
materials suitable for all specified service conditions.

4.6.4.1 Main inlet and outlet connections for radially split machines shall be located in the outer casing,
not in the end heads. On radially split overhung design machines, the process inlet connection may be in the
end head.
