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 3.
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 part of ISO 10440 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 10440-2 was prepared by Technical Committee ISO/TC 118, Compressors, pneumatic
tools and pneumatic machines and Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum and natural gas industries, Subcommittee SC 6, Processing equipment and systems.
ISO 10440 consists of the following parts, under the general title Petroleum and natural gas industries — Rotary-
type positive-displacement compressors:
Part 1: Process compressors (oil-free)
Part 2: Packaged air compressors (oil-free)

Introduction
This part of ISO 10440 is based on the 2nd edition API 619 and upon the accumulated knowledge and experience
of manufacturers and users of oil-free rotary compressors. The objective of this publication is to provide a purchase
specification to facilitate the manufacture and procurement of oil-free rotary compressors for general petroleum and
natural gas industry services but its use is not limited to these services.
The purpose of this part of ISO 10440 is to establish minimum requirements for design and construction so that the
equipment will be suitable for the purpose for which it is required. This limitation in scope is one of charter rather
than interest and concern. Energy conservation and protection of environment are matters of increasing concern
and are important in all aspects of equipment design, application and operation. The manufacturers and users of
equipment should aggressively pursue alternative innovative approaches which improve energy utilization and/or
minimize environmental impact without sacrificing safety or reliability. Such approaches should be thoroughly
investigated and purchase options should increasingly be based on the estimation of whole life costs and the
environmental consequences rather than acquisition costs alone.
This part of ISO 10440 requires the purchaser to specify certain details and features.
For effective use of this part of ISO 10440 and ease of reference to the text, the use of the data sheets in annex A
is recommended.
Users of this part of ISO 10440 should be aware that further or differing requirements may be needed for individual
applications. This part of ISO 10440 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
applicable where there is innovative or developing technology. Where an alternative is offered, the vendor should
identify any variations from this part of ISO 10440 and provide details.

4.1.10 Packaged compressors shall perform on the test stand to the specified acceptance criteria. Other
guarantees should be agreed upon between the purchaser and the vendor.
z 4.1.11 Many factors (such as pipe loadings, nozzle loadings, alignment at operating conditions, piping and
foundation vibrations from other equipment installed locally, supporting structure, handling during shipment and
handling and assembly at site) may adversely affect site performance.
To minimize the influence of these factors, the vendor shall propose a total compressor package. Allowable loads
on the interconnecting flanges are specified by the vendor.
z 4.1.12 All electrical components and installations shall be suitable for the area classification and grouping
specified by the purchaser on the data sheets and be in accordance with the local codes specified.
z 4.1.13 Control of the sound level from the packaged compressors shall be presented by the vendor. The
equipment furnished shall conform to the requirements and local codes as specified by the purchaser and as
detailed on the data sheets.
z 4.1.14 Water and/or oil separation shall be included in the package. The vendor shall prepare contamination
levels. Where needed, contamination levels shall be specified by the purchaser.
z 4.1.15 The purchaser shall specify whether the installation is indoors (heated or unheated) or outdoors (with or
without a roof) and the weather or environmental conditions in which the equipment shall operate (including
maximum and minimum temperatures and unusual humidity or dust problems). The unit and its auxiliaries shall be
suitable for operation in these specified conditions. For the purchaser's guidance, the vendor shall list in the
proposal any special protection that the purchaser is required to supply.
4.2 Pressure casing
4.2.1 The hoop stress values used in the design of the casings shall not exceed the maximum allowable stress
values in tension, as specified in the design code in 4.1.1, at the maximum and minimum operating temperature of
the materials used.
4.2.2 The maximum allowable working pressure of the casing shall be at least equal to the specified relief valve
setting.
4.2.3 Split pressure level casings shall be avoided. If the casing is split into two or more pressure levels, the
vendor shall define the physical limits and the maximum allowable working pressure of each part of the casing. See
7.1 h) for proposal requirements.
4.2.4 Each axially split casing shall be sufficiently rigid to allow removal and replacement of its upper half without
disturbing rotor-to-casing running clearances.
4.2.5 Casings and supports shall be designed to have sufficient strength and rigidity to limit a change of shaft
alignment to 50 mm at the coupling flange caused by the worst combination of pressure, torque, allowable piping
forces and moments. Supports and alignment bolts shall be rigid enough to permit the machine to be moved by the
use of its lateral, axial and vertical jackscrews.
4.2.6 Axially split casings shall use a metal-to-metal joint (with a suitable joint compound) that is tightly
maintained by suitable bolting. Gaskets (including string type) shall not be used on the axial joint. When gasketed
joints are used between the end covers and the cylinder of radially split casings, they shall be securely maintained
by confining the gaskets.
4.2.7 Jacket cooling systems shall be designed to positively prevent leakage of the process stream into the
coolant. Coolant passages shall not open into casing joints.
4.2.8 Jackscrews, guide rods and casing alignment dowels shall be provided to facilitate disassembly and
reassembly. When jackscrews are used as a means of parting contacting faces, one of the faces shall be relieved
(counter-bored or recessed) to prevent a leaking joint or improper fit caused by marring. Guide rods shall be of
sufficient length to prevent damage to the internals or casing studs by the casing during disassembly and
