Petroleum and natural gas industries - Packaged reciprocating gas compressors (ISO 13631:2002)

ISO 13631:2002 gives requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of packaged skid-mounted, reciprocating, separable or integral compressors with lubricated cylinders and their prime movers, for use in the petroleum and natural gas industries for the compression of hydrocarbon gas.
It is also applicable to all necessary auxiliary equipment, such as water and gas coolers, silencers, emission control equipment, filters, separators, control panel, piping, etc., required to install an operable unit in compliance with the purchase specifications and with the intent of minimizing field construction and field-purchased equipment.
ISO 13631:2002 is not applicable to the following:
reciprocating compressors for petroleum and natural gas industries covered by ISO 13707;
column-mounted compressors;
non-lubricated compressors;
compressors having trunk-type (automotive-type) pistons that also serve as crossheads;
utility or instrument air compressors with a discharge gauge pressure of 0,9 MPa (9 bar) or less;
compressors driven by diesel engine, gas turbine and steam turbine prime movers.

Erdöl- und Erdgasindustrie - Gaskolbenkompressoranlagen (ISO 13631:2002)

In dieser Internationalen Norm werden Anforderungen an und Empfehlungen für Konstruktion, Werkstoffe, Fertigung, Inspektion, Prüfung und Versandvorbereitungen für skid-montierte und separierbare oder in eine komplette Anlage integrierte Kolbenkompressoren mit geschmierten Zylindern und den zugehörigen Antriebsmaschinen festgelegt, die für die Anwendung in der Erdöl- und Erdgasindustrie zur Verdichtung von Kohlenwasserstoffgas vorgesehen sind.
Die Norm gilt auch für alle zugehörigen Zusatzausrüstungen, z. B. Wasser- und Gaskühler, Schalldämpfer, Einrichtungen zur Emissionskontrolle, Filter, Abscheider, Steuerpulte, Rohrleitungen usw., die benötigt werden, um eine den Liefervorschriften entsprechende betriebsfähige Einheit mit dem Ziel zu installieren, Bauarbeiten vor Ort und den Kauf von speziell für den Einsatzort bestimmten Ausrüstungsgegenständen zu verringern.
Die vorliegende Internationale Norm gilt nicht für
3 in der Erdöl- und Erdgasindustrie angewendete Kolbenkompressoren, die in ISO 13707 erfasst werden;
3 stehende Kompressoren;
3 ungeschmierte Kompressoren;
3 Kompressoren mit Tauchkolben (mit Eigenantrieb), die auch als Geradführung dienen;
3 Kompressoren für Betriebsmittel oder Instrumentenluft, die einen Austrittsüberdruck von maximal 0,9 MPa (9 bar) erzeugen;
3 Kompressoren, deren Antriebsmaschine ein Dieselmotor, eine Gasturbine oder eine Dampfturbine ist.

Industries du pétrole et du gaz naturel - Unités de compresseurs alternatifs a gaz (ISO 13631:2002)

L'ISO 13361:2002 spécifie les exigences et fournit des recommandations pour la conception, les matériaux, la fabrication, le contrôle, les essais et la préparation en vue de l'expédition des compresseurs séparables ou intégrés alternatifs montés sur châssis et assemblés, équipés de cylindres lubrifiés et de leurs machines d'entraînement, destinés à être utilisés dans les industries du pétrole et du gaz naturel pour la compression des hydrocarbures.
Elle est applicable également à tous les équipements auxiliaires nécessaires, tels que les refroidisseurs d'eau et de gaz, les silencieux, les dispositifs antipollution, les filtres, les séparateurs, les tableaux de commande, les canalisations, requis pour installer un dispositif fonctionnel conforme aux spécifications de l'acheteur et à l'objectif de réduire l'étendue du site de construction ainsi que les équipements acquis sur le terrain.
L'ISO 13361:2002 n'est pas applicable aux compresseurs suivants:
compresseurs alternatifs destinés aux industries du pétrole et du gaz naturel et couverts par l'ISO 13707;
compresseurs montés sur colonnes;
compresseurs non lubrifiés;
compresseurs à pistons fourreaux (type automobile) qui servent également de crosses;
compresseurs à air pour centrale ou instrumentation avec une pression manométrique de refoulement inférieure ou égale à 0,9 MPa (9 bar);
compresseurs entraînés par un moteur diesel ou par des machines d'entraînement à turbine à gaz ou à vapeur.

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.

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 International Standard may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 13631 was prepared by Technical Committee ISO/TC 118, Compressors, pneumatic tools and pneumatic

machines.

Annex B forms a normative part of this International Standard. Annexes A, C, D and E are for information only.

Introduction

This International Standard is based on API specification 11P second edition, November 1989.

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 applicable 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 subclause or paragraph indicates that either a decision is required or further

information is to be provided by the purchaser. This information should be indicated on the data sheets (see

annex A).
