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)

ISO 10440-2:2001(E)
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 Basic design
4.1 General

4.1.1 The purchaser and the vendor shall agree upon the pressure equipment code to be applied (e.g. ASME

Section VIII Division 1 for design, Section IX for welding, etc.). This shall be specified on the data sheet

(see annex A).

4.1.2 Equipment shall be capable of running safely to the trip speed at 110 % relief valve setting, and specified

maximum differential pressure.

NOTE To run safely involves factors other than differential pressure, such as maximum discharge temperature or limiting

driver power.

4.1.3 Cooling water systems shall be designed for the following conditions unless otherwise specified.

 Velocity in exchanger tubes 1,5 m/s to 2,5 m/s
 Maximum allowable working pressure > 5 bar (> 0,5 MPa)
 Test pressure > 7,7 bar (> 0,77 MPa)
 Maximum pressure drop 1 bar (0,1 MPa)
 Maximum inlet temperature 32 °C
 Maximum outlet temperature 49 °C
 Maximum temperature rise 17 °C
 Minimum temperature rise 11 °C
 Fouling factor on water side 0,35 m2.K/kW
Provision shall be made for complete venting and draining of the system.

4.1.4 The arrangement of the equipment, including piping and auxiliaries, shall be developed jointly by the

purchaser and the package vendor. The arrangement shall provide adequate clearance areas and safe access for

operation and maintenance.

4.1.5 All equipment shall be designed to permit rapid and economical maintenance. Major parts such as casing

components and bearing housings shall be designed (shouldered or dowelled) and manufactured to ensure

accurate alignment on reassembly.

4.1.6 Unless otherwise specified by the purchaser, spare parts for these compressors and auxiliaries shall meet

all the requirements of the original equipment supplied.

4.1.7 Oil reservoirs and housings that enclose moving lubricated parts (such as bearings, shaft seals, highly

polished parts, instruments and control elements) shall be designed to minimize contamination by moisture, dust

and other foreign matter during periods of operation or idleness.

4.1.8 When special tools and fixtures are required to disassemble, assemble or maintain the unit, they shall be

included in the quotation and furnished as part of the initial supply of the compressor. For multi-unit installations,

the requirements for quantities of special tools and fixtures shall be mutually agreed upon by the purchaser and the

vendor.

4.1.9 When special tools are provided, they shall be packaged in separate, rugged boxes and marked “special

tools for (tag/item number)”. Each tool shall be tagged to indicate its intended use.

SIST EN ISO 10440-2:2004
ISO 10440-2:2001(E)

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

reassembly. Lifting lugs or eyebolts shall be provided for lifting only the top half of the casing. Methods of lifting the

assembled machine shall be specified by the vendor.

4.2.9 For corrosion resistance, wear resistance and running in, overlay cladding or plating may be applied to the

casing wall. The end wall may be similarly lined or have compatible end plates provided. The vendor shall include

details of his procedures in the casing design proposal.

NOTE This procedure may require an overbore of the casing during manufacture prior to final machining.

4.2.10 Details of threading shall be in accordance with ISO 262.
4.2.11 Studs are preferred to cap screws.

4.2.12 A clearance shall be provided at bolting locations to permit the use of socket or box wrenches. The vendor

shall supply any required special tools and fixtures.

4.2.13 Socket, slotted nut or spanner bolting shall not be used unless specifically approved by the purchaser.
