SIST EN ISO 14692-1:2017

Petroleum and natural gas industries - Glass-reinforced plastics (GRP) piping - Part 1: Vocabulary, symbols, applications and materials (ISO 14692-1:2017)

This document defines the applications, pressure rating methodology, the classification of the products
according to application, type of joint and resin matrix and the limitations to both the materials of
construction and the dimensions. It also lists the terms, definitions and symbols used and provides
guidance in the use and interpretation of ISO 14692-2, ISO 14692-3 and ISO 14692-4.
ISO 14692 (all parts) is applicable to GRP piping systems that 1) utilize joints that are capable of
restraining axial thrust from internal pressure, temperature change and fluid hydrodynamic forces
and 2) have a trapezoidal shape for its design envelope. It is primarily intended for offshore applications
on both fixed and floating topsides facilities, but it can also be used for the specification, manufacture,
testing and installation of GRP piping systems in other similar applications found onshore, e.g.
produced-water, firewater systems and general industrial use.
For floating installations, reference is made to the design, construction and certification standards for
the hull or vessel, since these can allow alternative codes and standards for GRP piping associated with
marine and/or ballast systems. However, it is recommended that ISO 14692 (all parts) be used for such
applications to the maximum degree attainable.
ISO 14692 (all parts) can also be used as the general basis for specification of pipe used for pump
caissons, stilling tubes, I-tubes, seawater lift risers and other similar items.

Industries du pétrole et du gaz naturel - Canalisations en plastique renforcé de verre (PRV) - Partie 1: Vocabulaire, symboles, applications et matériaux(ISO 14692-1:2017)

ISO 14692-1:2017 définit les applications, la méthodologie pour la pression nominale, la classification des produits conformément à l'application, le type d'assemblage et de matrice résine et les limites concernant les matériaux de construction et les dimensions. Il répertorie également les termes, définitions et symboles utilisés et fournit des lignes directrices pour l'utilisation et l'interprétation de l'ISO 14692‑2, de l'ISO 14692‑3 et de l'ISO 14692‑4.
L'ISO 14692 (toutes les parties) s'applique aux systèmes de tuyauteries en PRV qui 1) utilisent des assemblages pouvant limiter un effort axial du à la pression interne, à un changement de température et à des forces hydrodynamiques du fluide et dont 2) l'enveloppe de conception présente une forme trapézoïdale. Elle est avant tout destinée à des applications en mer sur des plates-formes fixes et des supports flottants, mais elle peut également être utilisée pour la spécification, la fabrication, les essais et l'installation de systèmes de tuyauteries en PRV destinés à d'autres applications similaires à terre, par exemple des systèmes d'eau de gisement, des systèmes d'eau incendie et un usage industriel général.
Pour les installations flottantes, se référer aux normes de conception, de construction et de certification de la coque ou du bâtiment car celles-ci peuvent autoriser l'application d'autres codes et normes pour les tuyauteries en PRV associées à des systèmes maritimes et/ou de ballastage. Pour ces applications, il est toutefois recommandé d'utiliser l'ISO 14692 (toutes les parties) dans la mesure du possible.
L'ISO 14692 (toutes les parties) peut également être utilisée comme base générale pour la spécification des tubes utilisés pour les caissons de pompes, les tubes de distillation, les tubes en I, les colonnes montantes des pompes d'aspiration d'eau de mer et autres éléments similaires.

Industrija za predelavo nafte in zemeljskega plina - S steklenimi vlakni ojačeni polimerni cevovodi (GRP) - 1. del: Slovar, simboli, uporaba in materiali (ISO 14692-1:2017)

Ta dokument opredeljuje uporabo, metodologijo za določanje stopnje tlaka, razvrstitev proizvodov glede na uporabo, vrsto matrice spojev in smole ter omejitve glede materialov za izdelavo in dimenzij. Navaja tudi izraze, opredelitve in simbole, ki se uporabljajo, ter podaja smernice za uporabo in razumevanje standardov ISO 14692-2, ISO 14692-3 in ISO 14692-4.
Standard ISO 14692 (vsi deli) se uporablja za s steklenimi vlakni ojačene polimerne cevovodne sisteme, ki 1) uporabljajo spoje za morebitno omejitev osnega potiska, ki je posledica notranjega tlaka, temperaturne spremembe in hidrodinamičnih sil, ter 2) katerih načrtovani ovoj je trapezne oblike. Namenjen je predvsem za uporabo na morju na palubah nepremičnih in plavajočih ploščadi, vendar se lahko uporablja tudi za specifikacijo, izdelavo, preskušanje in namestitev s steklenimi vlakni ojačenih polimernih cevovodnih sistemov, ki se uporabljajo za podobne namene na morju, npr. dobavo pitne vode, sisteme požarne vode in splošno industrijsko uporabo.
V zvezi s plavajočimi ploščadmi se ta standard sklicuje na standarde za načrtovanje, izdelavo in certificiranje trupa ali plovila, saj lahko ti dovoljujejo alternativne kode in standarde za s steklenimi vlakni ojačene cevovode, ki se uporabljajo v pomorskih in/ali balastnih sistemih. Kljub temu se priporoča, da se v največji možni meri za te uporabe uporablja standard ISO 14692 (vsi deli).
Standard ISO 14692 (vsi deli) se lahko uporablja tudi kot splošna osnova za specifikacijo cevi, ki se uporabljajo za kesone, cevi za umirjanje, I-cevi, dvižne cevi za morsko vodo in druge podobne elemente.

Introduction
0.1 General
The objective of ISO 14692 (all parts) is to provide the oil and gas industry, as well as the supporting
engineering and manufacturing industry, with mutually agreed specifications and recommended
practices for the purchase, qualification, manufacturing, design, handling, storage, installation,
commissioning and operation of GRP piping systems.
This document, provides guidance in the use and interpretation of the other parts of ISO 14692. This
document contains the following annexes:
— Annex A (informative) explaining the principle;
— Annex B (informative) providing guidance on scope limitations;
— Annex C (normative) containing the enquiry sheet;
— Annex D (normative) providing wall thickness definitions;
— Annex E (informative) describing selection of part factor f in bid process;
3,est
— Annex F (informative) containing a worked example.
0.2 Basic steps in use of ISO 14692 (all parts)
Figure 1 identifies the eight basic steps involved in the use of ISO 14692 (all parts) that are further
explained below.
Step 1: The bid process. The principal completes an enquiry sheet (see Annex C) that defines the
design pressures and temperatures of the piping system as well as the application, required pipe sizes
and required components (bends, tees, reducers, flanges, etc.). The principal also verifies that the
scope of the application is within the limits of ISO 14692 (all parts) (see Annex B). The principal and
manufacturer also comes to an agreement on the value of the estimated value of the part factor f
3,est
(see Annex E).
In some cases, the manufacturer can wish to offer a product that 1) meets or exceeds the requirements
in the enquiry sheet and 2) has already been manufactured, qualified and inspected per ISO 14692-2. In
this case, Steps 2 through 4 would not need to be repeated.
Step 2: Manufacturer's data. Recognizing that long-term regression testing can easily take two or more
years to complete, the manufacturer will most likely have already selected target values for MPR , the
xx
long-term envelope(s) and the minimum reinforced wall thicknesses. The manufacturer determines the
appropriate gradient and rd can then be calculated to suit the survival test duration. Additional
1 000,xx
basic data such as pipe sizes, wall thicknesses, SIFs, production processes and jointing instructions are
also provided.
Step 3: Qualification process. The manufacturer conducts survival tests to qualify the pressure and
temperature. If applicable, the manufacturer also qualifies fire performance and electrical conductivity
properties. Elastic properties, potable water certification, impact and low temperature performance
are also addressed in this step. Just as in Step 2, the manufacturer can have already completed part or
all of the qualification process prior to Step 1.
Step 4: Quality programme. The basic requirements for the manufacturer's quality management system
are defined.
Step 5: Generate envelopes. This is the first major step in ISO 14692-3. Partial factors and part factors
are identified and combinations of these factors are determined. Formulae are then provided to
calculate the design envelope(s).

Step 6: Stress analysis. The flexibility factors and SIFs to be used in the stress analysis are identified.
The allowable values for vertical deflection, stresses and buckling are also defined. An analytical
formula for external pressure is provided.
Step 7: Bonder training and assessment. This is the first major step in ISO 14692-4 where the bonder
training and assessment process is defined.
Step 8: Installation, field hydrotest. This is the last major step where installation issues are addressed.

0.3 Other standards
GRP piping products are used in a wide variety of applications in both industrial and municipal service.
For some applications, ISO 14692 (all parts) can be properly considered as the basis for piping and
pipeline selection and design. In all applications, the selection of the appropriate standard for any
particular application takes into consideration the design life of the project, the service temperature,
the corrosive nature of the fluid, whether the intended installation is above ground or buried and what
type of joining system is to be used. Depending on the service conditions, other GRP piping standards
can be more appropriate and better suited than ISO 14692 (all parts) for the entire or part of the system.
This is particularly the case for aqueous applications of both a municipal and industrial nature where
the pipelines are generally buried and axial tensile loads are minimal.
Other widely used GRP piping standards include
— ISO 10639,
— ISO 10467,
— API 15HR,
— ASTM D3262-11,
— ASTM D3517-14,
— ASTM D3754-14,
— AWWA C950-07,
— EN 1796:2013, and
— EN 14364:2013.
ISO 14692 (all parts) is not intended to be applied to sewerage and drainage applications, although it
can provide useful guidance in specific areas not addressed in alternative standards. ISO 14692 (all
parts) is also not specifically intended for non-structural applications such as open drain systems and
other low-pressure piping applications.
ISO 14692 (all parts) covers all the main components that form part of a GRP pipeline and piping
system (plain pipe, bends, reducers, tees, supports and flanged joints) with the exception of valves and
instrumentation.
0.4 Structure of ISO 14692 (all parts)
ISO 14692-2, ISO 14692-3 and ISO 14692-4 follow the individual phases in the life cycle of a GRP piping
system, i.e. from qualification and manufacture through design to fabrication, installation, operation
and decommissioning.
Each part is therefore aimed at the relevant parties involved in that particular phase.
— ISO 14692-1: Vocabulary, symbols, applications and materials. The scope is presented in Clause 1 and
it provides guidance in the use of the other three parts of ISO 14692. Main users are envisaged to
include all parties in the life cycle of a typical GRP piping system. This document should be used in
conjunction with the part of specific relevance.
— ISO 14692-2: Qualification and manufacture. Its objective is to enable the supply of GRP components
with known and consistent properties from any source. Main users of the document are envisaged
to be the principal, the manufacturer, certifying authorities and government agencies.
— ISO 14692-3: System design. Its objective is to ensure that piping systems, when designed using the
components qualified in ISO 14692-2, meet the specified performance requirements. Main users of

the document are envisaged to be the principal, the manufacturer, design contractors, certifying
authorities and government agencies.
— ISO 14692-4: Fabrication, installation, inspection and maintenance. Its objective is to ensure
that installed piping systems meet the specified performance requirements throughout their
service life. Main users of the document are envisaged to be the principal, the manufacturer,
fabrication/installation contractors, repair and maintenance contractors, certifying authorities
and government agencies.

Part 1:
Vocabulary, symbols, applications and materials
1 Scope
This document defines the applications, pressure rating methodology, the classification of the products
according to application, type of joint and resin matrix and the limitations to both the materials of
construction and the dimensions. It also lists the terms, definitions and symbols used and provides
guidance in the use and interpretation of ISO 14692-2, ISO 14692-3 and ISO 14692-4.
ISO 14692 (all parts) is applicable to GRP piping systems that 1) utilize joints that are capable of
restraining axial thrust from internal pressure, temperature change and fluid hydrodynamic forces
and 2) have a trapezoidal shape for its design envelope. It is primarily intended for offshore applications
on both fixed and floating topsides facilities, but it can also be used for the specification, manufacture,
testing and installation of GRP piping systems in other similar applications found onshore, e.g.
produced-water, firewater systems and general industrial use.
For floating installations, reference is made to the design, construction and certification standards for
the hull or vessel, since these can allow alternative codes and standards for GRP piping associated with
marine and/or ballast systems. However, it is recommended that ISO 14692 (all parts) be used for such
applications to the maximum degree attainable.
ISO 14692 (all parts) can also be used as the general basis for specification of pipe used for pump
caissons, stilling tubes, I-tubes, seawater lift risers and other similar items.
Typical oil and gas industry applications for the use of GRP piping and pipelines include those listed in
Table 1.

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.

Step 1: The Bid Process. Here, the principal completes an enquiry sheet (refer to Annex D) that defines the
design pressures and temperatures of the piping system as well as the application, required pipe sizes and
required components (bends, tees, reducers, flanges, etc.). The principal also verifies that the scope of the
application is within the limits of ISO 14692 (refer to Annex C). The principal and manufacturer shall also
come to an agreement on the value of the estimated value of the part factor f (refer to Annex F).
3,est
In some cases, the manufacturer may wish to offer a product that 1) meets or exceeds the requirements in the
Enquiry sheet and 2) has already been manufactured, qualified and inspected per ISO 14692-2. In this case,
steps 2 thru 4 would not need to be repeated.
Step 2: Manufacturer's Data. Recognizing that long term regression testing can easily take 2 or more years to
complete, the manufacturer will most likely have already selected target values for MPR , the long term
xx
envelope(s) and the minimum reinforced wall thicknesses. The manufacturer shall determine the appropriate
gradient and rd can then be calculated to suit the survival test duration. Additional basic data such as
1 000,xx
pipe sizes, wall thicknesses, SIFs, production processes and jointing instructions shall also be provided.
Step 3: Qualification Process. Here, the manufacturer conducts survival tests to qualify the pressure and
temperature. If applicable, the manufacturer shall also qualify fire performance and electrical conductivity
properties. Elastic properties, potable water certification, impact and low temperature performance are also
addressed in this step. Just as with Step 2, the manufacturer may have already completed part or all of the
qualification process prior to Step 1, the bid process.
Step 4: Quality Programme. Step 4 defines the basic requirements for the manufacturer's quality management
system.
Step 5: Generate Envelopes. Step 5 is the first major step in Part 3. Here, partial factors and part factors are
identified and combinations of these factors are determined. Formulae are then provided to calculate the
design envelope(s).
Step 6: Stress Analysis. Step 6 identifies the flexibility factors and SIFs to be used in the stress analysis. It
also defines the allowable values for vertical deflection, stresses and buckling. An analytical formula for
external pressure is provided.
Step 7: Bonder Qualification. Step 7 is the first major step in Part 4 where the bonder qualification process is
defined.
Step 8: Installation, Field Hydrotest. Step 8 is the last major step where installation issues are addressed.

DRAFT INTERNATIONAL STANDARD ISO/DIS 14692-1

Petroleum and natural gas industries — Glass-reinforced
plastics (GRP) piping — Part 1: Vocabulary, symbols,
applications and materials
1 Terms, definitions, symbols and abbreviated terms
For terms, definitions, symbols and abbreviated terms, refer to Annex A.
2 Scope, applications and document structure
2.1 Scope
This part, Part 1 of ISO 14692, defines the applications, pressure rating methodology, the classification of the
products according to application, type of joint and resin matrix and the limitations to both the materials of
construction and the dimensions. It also lists the terms, definitions and symbols used and provides guidance
in the use and interpretation of the other Parts of ISO 14692, namely Parts 2, 3 and 4.
ISO 14692 (all parts) is applicable to GRP piping systems that 1) utilize joints that are capable of restraining
axial thrust from internal pressure, temperature change and fluid hydrodynamic forces and 2) have a
trapezoidal shape for its design envelope. It is primarily intended for offshore applications on both fixed and
floating topsides facilities, but it may also be used for the specification, manufacture, testing and installation of
GRP piping systems in other similar applications found onshore, e.g. produced-water, firewater systems and
general industrial use.
2.2 Applications
ISO 14692 (all parts) applies to the specification, manufacture, testing and installation of GRP piping and
pipeline systems associated with oil and gas industry production, processing and utility service applications. It
is intended for offshore applications on both fixed and floating topsides facilities, but it may also be used as
guidance for GRP piping and pipeline systems in oil and gas industry applications found onshore.
For floating installations, reference should be made to the design, construction and certification standards for
the hull or vessel, since these may allow alternative codes and standards for GRP piping associated with
marine and/or ballast systems. However, it is recommended that ISO 14692 (all parts) be used for such
applications to the maximum degree attainable.
ISO 14692 (all parts) may also be used as the general basis for specification of pipe used for pump caissons,
stilling tubes, I-tubes, seawater lift risers and other similar items.
Typical oil and gas industry applications for the use of GRP pipe include those listed in Table 1.

NOTE 1 Some applications, such as wet chlorine gas, hydrogen chloride gas, hydrochloric acid, sodium
hydroxide and sodium hypochlorite, require a barrier liner and may require specific corrosion resistant
resins. Consult manufacturer for recommendations.

2.2.1 Other Standards
GRP piping products are used in a wide variety of applications in both industrial and municipal service. For
some applications, ISO14692 (all parts) may be properly considered as the basis for piping and pipeline
selection and design. In all applications, the selection of the appropriate standard for any particular application
must take into consideration the design life of the project, the service temperature, the corrosive nature of the
fluid, whether the intended installation is above ground or buried and what type of joining system is to be used.
Depending on the service conditions, other GRP piping standards may be more appropriate and better suited
than ISO 14692 (all parts) for all or part of the system. This is particularly the case for aqueous applications of
both a municipal and industrial nature where the pipelines are generally buried and axial tensile loads are
minimal. Other widely used GRP piping standards include:

ISO 14692 is not intended to be applied to sewerage and drainage applications though it may provide useful
guidance in specific areas not addressed in alternative standards. ISO 14692 is also not specifically intended
for non-structural applications such as open drain systems and other low pressure piping applications.
ISO 14692 (all parts) covers all the main components that form part of a GRP pipeline and piping system (pipe,
bends, reducers, tees, supports, flanged joints) with the exception of valves and instrumentation.
2.3 Document structure
ISO 14692-2, ISO 14692-3 and ISO 14692-4 follow the individual phases in the life cycle of a GRP piping
system, i.e. from qualification and manufacture through design to fabrication, installation, operation and
decommissioning.
Each part is therefore aimed at the relevant parties involved in that particular phase.
 Part 1: Vocabulary, symbols, applications and materials. It provides guidance in the use of the other 3
parts of ISO 14692, namely Parts 2, 3 and 4. It defines the applications, pressure rating methodology, the
classification of the products according to application, type of joint and resin matrix and the limitations to
both the materials of construction and the dimensions. It also lists the terms, definitions and symbols used.
Main users are envisaged to include all parties in the life cycle of a typical GRP piping system.
ISO 14692-1 should be used in conjunction with the part of specific relevance.
 Part 2: Qualification and manufacture. Its objective is to enable the supply of GRP components with
known and consistent properties from any source. Main users of the document are envisaged to be the
principal, the manufacturer, certifying authorities and government agencies.
 Part 3: System design. Its objective is to ensure that piping systems, when designed using the
components qualified in ISO 14692-2, meet the specified performance requirements. Main users of the
document are envisaged to be the principal, the manufacturer, design contractors, certifying authorities
and government agencies.

Accordingly, for GRE, MPR should always be equal to or greater than P . For GRUP and GRVE, MPR
65 des 21
should always be equal to or greater than P
des.
NOTE Since MPR is the default MPR for GRE, this will tend to add some factor of safety in the design of the
65 xx
hydrotest loading case (since the hydrotest loading case is conducted at ambient temperature, but the design envelope for
the hydrotest loading case will be based on the long term envelope at 65 °C). The same is not true for GRUP and GRVE.
