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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10439-1 was prepared by Technical Committee ISO/TC 118, Compressors and pneumatic tools,
machines and equipment, Subcommittee SC 1, Process 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.

Petroleum, petrochemical and natural gas industries — Axial

Part 4:
Expander-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 expander-compressors, in addition to the general requirements specified in
ISO 10439-1.
This scope covers only expanders and compressors on a common shaft (expander-
compressor). This scope does not apply to expanders with separate output shafts (e.g.,
generator drives). Hot gas expanders over 300 °C (570 °F) are not covered in this standard.
2 Normative References
The following referenced documents are indispensible for the application of this document.
For dated references, only the editions cited applies. For undated references, the latest
edition of the referenced document (including any amendments) applies.

For the purposes of this document, the terms, abbreviated terms and definitions given in
ISO 10439-1 apply.

4.1 Dimensions and units
The dimensional and unit requirements of ISO 10439-1 shall apply.

4.2 Statutory requirements
The statutory requirements of ISO 10439-1 shall apply.
4.3 Unit responsibility
The unit responsibilities of ISO 10439-1 shall apply
4.4 Basic Design
4.4.1 The expander shall meet at least 98 % of the predicted efficiency at the normal U/C
ratio (see 6.3.5.1.1). The compressor shall deliver at least 98 % of the normal head at the
normal capacity. The compressor power at the normal condition shall not be more than 106 %
of that available from the expander, nor shall it be less than 96 % of that available from the
expander.
NOTE Compressor-loaded expanders achieve a power balance that determines the speed of the
machine. There is generally no speed control governor to control the speed the way other turbine driven
compressors are controlled. If the expander power is more than expected, then the speed of the
machine will be higher than predicted. If the compressor power is more than expected, then the speed
of the machine will be lower than predicted. The above tolerances are needed to set limits beyond which
hardware changes may be required to achieve a reasonable normal speed.
4.4.2 The compressor head-capacity characteristic curve shall rise continuously from the
rated point to surge. The compressor shall be suitable for continuous operation at any
capacity on the predicted performance curve(s) at least 10 % greater than the predicted surge
capacity shown in the proposal.
NOTE It is common for flow to be bypassed around the compressor during normal operation.
4.5 Materials
Materials shall be in accordance with 4.5 of ISO 10439-1. Refer to Annex D for a table of
typical materials.
4.5.1 If traces of mercury have been specified, aluminum impellers shall be treated by
anodizing or other approved methods.
4.6 Casings
Casings shall be in accordance with 4.6 of ISO 10439-1 and the additional requirements as
follows.
4.6.1 Pressure-containing Casings
● 4.6.1.1 The maximum allowable working pressure of the casing(s) shall be at least equal
to the relief valve set pressure(s) specified by the purchaser.
4.6.1.1.1 If a relief valve set pressure is not specified, the maximum allowable working
pressure of an expander casing shall be at least 1.1 times the maximum specified inlet
pressure (gauge). System pressure protection shall be furnished by the purchaser.

ISO/DIS 10439-4:2010
4.6.1.1.2 If a relief valve set pressure is not specified, the maximum allowable working
pressure of the compressor casing of an expander-compressor shall be at least 1.25 times
the maximum specified discharge pressure (gauge). System pressure protection shall be
furnished by the purchaser.
4.6.1.1.3 When the purchaser has not supplied a relief valve setting, he shall be responsible
for insuring that furnished relief valves are compatible with casing ratings as set by 4.6.1.1.1
and 4.6.1.1.2.
4.6.1.2 “O” rings, gaskets or other sealing devices which may be used on radially spilt
casings shall be confined in machined grooves and shall be made of materials suitable for all
specified service conditions.
4.6.1.3 Provisions for lifting the casings and removing the center section shall be provided.
4.6.1.4 The expander-compressor casing shall be designed with sufficient strength to
contain parts which might separate in the event of uncontrolled overspeed.
4.6.2 Casing repairs
Casing repairs shall be in accordance with ISO 10439-1.
4.6.3 Material Inspection of Pressure containing parts
Material inspection of pressure containing parts shall be in accordance with ISO 10439-1.
