Petroleum, petrochemical and natural gas industries - Axial and centrifugal compressors and expander-compressors - Part 2: Non-integrally geared centrifugal and axial compressors (ISO 10439-2:2015)

This part of ISO 10439 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 672 for packaged plant
instrument air compressors.

L'ISO 10439-2:2015 spécifie les exigences minimales et fournit des recommandations pour les compresseurs axiaux, les compresseurs centrifuges mono-arbres à multiplicateur intégré et les compresseurs-détendeurs pour applications spéciales d'amenée de gaz ou de traitement d'air dans les industries du pétrole, de la pétrochimie et du gaz naturel. L'ISO 10439-2:2015 spécifie les exigences pour les compresseurs centrifuges sans multiplicateur intégré et axiaux, en complément des exigences générales spécifiées dans l'ISO 10439‑1. Ces machines ne sont pas dotées d'un multiplicateur intégré dans leur carter, mais peuvent avoir des engrenages externes.

Ta del standarda ISO 10439 določa minimalne zahteve in daje priporočila za aksialne kompresorje, radialne kompresorje z eno gredjo in vgrajenim gonilom ter ekspanzijske kompresorje za posebne namene, ki obdelujejo plin ali procesni zrak v petrokemični industriji ter industriji za predelavo nafte in zemeljskega plina. Ta del standarda ISO 10439, poleg splošnih zahtev, določenih v standardu ISO 10439-1, določa zahteve za radialne in aksialne kompresorje brez vključenega pogona. Ti stroji nimajo pogona integriranega v ohišje, ampak imajo zunanji pogon.
OPOMBA: Glej standard ISO 10439-3 za procesne kompresorje z vgrajenim pogonom ali API 672 za vdelane kompresorje instrumentalnega zraka.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction

This International Standard is based on the 7th edition of the American Petroleum Institute standard API 617.

Further or differing requirements might be needed for individual applications. This International

Standard is not intended to inhibit a supplier from offering, or the purchaser from accepting, alternative

equipment or engineering solutions for the individual application. This can be particularly appropriate

where there is innovative or developing technology. Where an alternative is offered, the supplier should

identify any variations from this part of ISO 10439 and provide details.

An asterisk (*) at the beginning of the paragraph of a clause or subclause indicates that either a decision

is required or further information is to be provided by the purchaser. This information is indicated on

data sheets or stated in the enquiry or purchase order (see examples in Annex A in this part of ISO 10439,

ISO 10439-3:2015, Annex A, and ISO 10439-4:2015, Annex A).
This International Standard includes the following annexes:
— Annex A: Datasheets;
— Annex B: Vendor (Supplier) data and drawing requirements (VDDR);
— Annex C: Centrifugal compressor nomenclature;
— Annex D: Typical materials;
— Annex E: Inspector’s checklist;
— Annex F: Nozzle forces and moments;
— Annex G: Full load, full pressure, full speed testing;

Annex A forms a normative part of this part of ISO 10439. Annex B to Annex G are for information only.

In this International Standard, where practical, US Customary units are included in parentheses for

information.

This part of ISO 10439 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

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 672 for packaged plant

instrument air compressors.

4.6 Casings

Casings shall be in accordance with ISO 10439-1:2015, 4.6 and 4.6.1 to 4.6.6 of this part of ISO 10439.

4.6.1 Pressure-containing casings

4.6.1.1 The purchaser should 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.

When a relief valve set pressure is not specified, the maximum allowable working pressure shall be at

least 125 % 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 supplier 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 1 380 kPa gauge (200 psi gauge). The partial pressure

of hydrogen shall be calculated by multiplying the highest specified mole (volume) per cent 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.

4.6.1.5 Axially split casings shall use a metal-to-metal joint (with a suitable joint compound compatible

with the process gas) that is tightly maintained by suitable bolting. Gaskets (including string type) shall

not be used on the axial joint. “O” rings retained in grooves machined into the flange facing of an axially

split casing joint can
