4 Fabrication and installation
4.1 Delivery, inspection and documentation of GRP piping
The quantity, MSP, nominal dimensions and relevant special requirements of all piping components
and prefabricated spools shall be verified for compliance with the purchase order. Shipments of piping
components that do not comply with the purchase order shall be reported to the responsible personnel
and to the pipe producer for corrective actions.
All piping components shall be visually inspected in accordance with Table A.1 for damage that can have
occurred during storage and shipment. Rejected components shall be replaced. If doubts concerning
the extent of defects occur during inspection, a specialist approved by the principal shall perform a
second inspection of the delivered items.
Adhesive bonding kits shall be inspected to ensure that the kits:
— contain all necessary materials;
— are not leaking or visibly damaged; and
— have at least six months remaining lifetime before the expiration of shelf-life.
All fire protection material shall be inspected to ensure that the original packaging is not damaged.
4.2 Handling and storage
The handling of the GRP components shall follow the requirements given in Annex B and the
requirements of the pipe manufacturer.
4.3 System design documentation
The principal shall provide the installer at least with the following information:
a) operating and design parameters:
1) design pressure;
2) design temperature (maximum and minimum);
3) T of the resin used in component manufacture;
g
4) T of the adhesive used in component manufacture, if appropriate;
g
5) MSP of each component and MSOP of each piping system;
6) mean and maximum velocity conditions in each piping system;
7) chemical resistance limitations, if applicable;
8) procedures to eliminate or control water hammer and cavitation, if applicable;
9) fire classification and location of fire-rated pipe, if applicable;
10) conductivity classification, location of conductive pipe, earth linkage/grounding requirements
and location of earthing points;
11) criticality rating;
b) system drawings and support requirements for heavy equipment;
c) preferred locations for connection of final joint in pipe loops, if appropriate;

d) system criticality and minimum requirements for inspection during installation.
4.4 Installer requirements
4.4.1 Personnel qualification
All pipe, fittings and related items shall be installed by qualified GRP pipe fitters, bonders or spool-
builders and thereafter approved by a qualified GRP piping inspector. GRP pipe fitters and GRP piping
inspectors shall be qualified according to the minimum requirements detailed in Annex C.
4.4.2 Health and safety
In general, all safety precautions set forth by the manufacturer of pipes and fittings, chemicals, etc.
shall be adopted. Materials safety data sheets should always be read before commencing work.
4.5 Installation
4.5.1 General requirements
All piping components shall be installed so that they are ideally stress-free and at least not over-
stressed, meaning that:
a) bending of pipes to achieve changes in direction, or forcing misaligned flanges together by over-
torquing bolts is not permitted;
b) the manufacturer’s recommendations for bolt-torquing sequence, torque increments and maximum
bolt torque shall be followed;
c) all supports shall be installed (location and function) as per system design.
Prefabricated pipework shall be fabricated in accordance with fully dimensioned piping isometrics.
Overall spool dimensions shall be sized, taking the following into consideration:
— site transport and handling equipment limitations;
— installation and erection limitations;
— limitations caused by the necessity to allow a fitting tolerance for installation (“cut-to-fit”
requirements).
If shown on isometric drawings, the fabrication shall include “cut-to-fit” lengths and field joints on
fabricated pieces to allow for the setting up of pipework accurately on-site between fixed points. “Cut-
to-fit” lengths shall be left square and plain.
The installer shall take the following considerations into account.
a) The need to avoid overstressing of GRP components by the forced pulling of GRP pipework to
facilitate alignment at joints, and particularly at flanged joints.
b) The need to prevent damage to joints when handling small-diameter thick-walled pipe, e.g. due to
fire protection.
NOTE This is because the high rigidity of the pipe concentrates loading at the thinner sections of pipe
wall adjacent to the joint.
c) The preferred location of the last site joint in a piping loop to ensure that necessary access is
available, since this joint is often the most difficult to complete.
d) Delays caused by the time required for adhesive or laminated joints to cure without being
disturbed. The scheduling of surrounding construction activities shall take into account the risk of
possible disturbances to such joints.

---------------------- Page: 15 ----------------------
SIST EN ISO 14692-4:2017
ISO 14692-4:2017(E)
e) The need to provide temporary protection for installed GRP piping if risk of mechanical damage is
high. The installer shall also consider correct sequencing of fabrication activities to minimize risk
of damage.
f) The need to prevent overheating of the GRP pipe material by electric surface heating, if applied.
Heat tracing should be loosely spirally wound onto GRP pipe in order to distribute the heat evenly
around the pipe wall. Heat distribution can be improved if aluminium foil is first wrapped around
the pipe.
g) Provision of suitable joints to facilitate isolation or access to the pipe for maintenance purposes.
4.5.2 Components fabricated on-site
All processes used to fabricate spoolpieces and components on-site, e.g. mitred elbows, tee pieces and
laterals, shall have been qualified according to procedures given in ISO 14692-2:2017, Clause 5.
4.5.3 Cutting
GRP pipe shall be cut according to the manufacturer’s instructions.
For adhesive-bonded connections, the pipe end shall be machined with a pipe shaver according to the
manufacturer’s recommendations.
4.5.4 Above ground application — Supports
GRP piping systems may be supported using the same principles as those for metallic piping systems.
However, due to the proprietary nature of piping systems, standard-size supports do not necessarily
match the pipe outside diameters. The use of saddles and elastomeric (neoprene) pads may allow the
use of standard-size supports.
The following guidelines to GRP piping support shall be followed.
a) Supports in all cases should have sufficient width to support the piping without causing damage
and should be lined with an elastomer or other suitable soft material.
b) Clamping forces, if applied, should be such that crushing of the pipe does not occur. Local crushing
can result from a poor fit and all-round crushing can result from over-tightening.
c) In all cases, support design should be in accordance with the manufacturer’s guidelines.
d) Supports should preferably be located on plain pipe sections rather than at fitti

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.

b) system drawings and support requirements for heavy equipment;
c) preferred locations for connection of final joint in pipe loops, if appropriate;
d) system criticality and minimum requirements for inspection during installation.
5.4 Installer requirements
5.4.1 Personnel qualification
All pipe, fittings and related items shall be installed by qualified GRP pipe fitters, bonders or spool-builders
and thereafter approved by a qualified GRP piping inspector. GRP pipe fitters and GRP piping inspectors shall
be qualified according to the minimum requirements detailed in Annex C.
5.4.2 Health and safety
In general, all safety precautions set forth by the manufacturer of pipes and fittings, chemicals, etc., shall be
adopted. Materials safety data sheets should always be read before commencing work.
5.5 Installation
5.5.1 General requirements
All piping components shall be installed so that they are ideally stress free and at least not over-stressed:
a) bending of pipes to achieve changes in direction, or forcing misaligned flanges together by over-torquing
bolts is not permitted;
b) the manufacturer’s recommendations for bolt-torquing sequence, torque increments and maximum bolt
torque shall be followed.
c) All supports shall be installed ( location and function ) as per system design.
Prefabricated pipework shall be fabricated in accordance with fully dimensioned piping isometrics. Overall
spool dimensions shall be sized taking the following into consideration:
a) site transport and handling equipment limitations;
b) installation and erection limitations;
c) limitations caused by the necessity to allow a fitting tolerance for installation (“cut-to-fit” requirements).
If shown on isometric drawings, the fabrication shall include “cut-to-fit” lengths and field joints on fabricated
pieces to allow for the setting up of pipework accurately on-site between fixed points. “Cut-to-fit” lengths shall
be left square and plain.
The installer shall give due consideration to the following:
a) the need to avoid overstressing of GRP components by the forced pulling of GRP pipework to facilitate
alignment at joints, and particularly at flanged joints;
b) the need to prevent damage to joints when handling small-diameter thick-walled pipe, e.g. due to fire
protection;
NOTE This is because the high rigidity of the pipe concentrates loading at the thinner sections of pipe wall adjacent to
the joint.

oSIST prEN ISO 14692-4:2015
ISO/DIS 14692-4
c) the preferred location of the last site joint in a piping loop to ensure that necessary access is available,
since this joint is often the most difficult to complete;
d) delays caused by the time required for adhesive or laminated joints to cure without being disturbed. The
scheduling of surrounding construction activities shall take into account the risk of possible disturbances
to such joints;
e) the need to provide temporary protection for installed GRP piping if risk of mechanical damage is high.
The installer shall also consider correct sequencing of fabrication activities to minimize risk of damage;
f) the need to prevent overheating of the GRP pipe material by electric surface heating, if applied. Heat
tracing should be loosely spirally wound onto GRP pipe in order to distribute the heat evenly around the
pipe wall. Heat distribution can be improved if aluminium foil is first wrapped around the pipe.;
g) provision of suitable joints to facilitate isolation or access to the pipe for maintenance purposes.
5.5.2 Components fabricated on-site
All processes used to fabricate spoolpieces and components on-site, e.g. mitred elbows, tee pieces and
laterals, shall have been qualified according to procedures given in 4.3 of ISO 14692-2.
5.5.3 Cutting
GRP pipe shall be cut according to the manufacturer’s instructions.
For adhesive-bonded connections, the pipe end shall be machined with a pipe shaver according to the
manufacturer’s recommendations.
5.5.4 Above ground application - supports
GRP piping systems may be supported using the same principles as those for metallic piping systems.
However, due to the proprietary nature of piping systems, standard-size supports may not necessarily match
the pipe outside diameters. The use of saddles and elastomeric (neoprene) pads may allow the use of
standard-size supports.
The following guidelines to GRP piping support should be followed;
a) Supports in all cases should have sufficient width to support the piping without causing damage and
should be lined with an elastomer or other suitable soft material.
b) Clamping forces, if applied, should be such that crushing of the pipe does not occur. Local crushing can
result from a poor fit and all-round crushing can result from over-tightening.
c) In all cases, support design should be in accordance with the manufacturer’s guidelines.
d) Supports should preferably be located on plain pipe sections rather than at fittings or joints.
e) Supports shall be spaced to avoid sag (excessive displacement over time) and/or excessive vibration for
the design life of the piping system.
f) Valves or other heavy attached equipment shall be adequately and if necessary (as determined from
system design calculations) independently supported.
g) GRP pipe shall not be used to support other piping, unless agreed with the principal.
h) Consideration shall be given to the support conditions of fire-protected GRP piping. Supports placed on
the outside of fire protection can result in loads irregularly transmitted through the coating, which can
result in shear/crushing damage and consequent loss of support integrity.

ISO/DIS 14692-4
i) GRP piping should be adequately supported to ensure that the attachment of hoses at locations such as
utility or loading stations does not result in the pipe being pulled in a manner that could overstress the
material.
j) The anchor or linestop support shall be capable of transferring the required axial loads to the supporting
structure without causing overstress of the GRP pipe material.
k) Anchor or linestop clamps are recommended to be placed between two double 180° saddles, adhesive-
bonded or laminated to the outer surface of the pipe. The manufacturer’s standard saddles are
recommended and shall be bonded using standard procedures.
5.5.5 Buried piping
a) In-situ conditions – an appreciation of the local soil conditions and water table should be obtained prior to
trench excavation.
b) Embedment materials – the local soil type should be identified in order to determine the support that can
be provided to the buried GRP pipe system. Other issues to consider include moisture content and
permeability which if inappropriately selected could lead to improper settlement.
c) Considerations for use of soil in backfill – the soil properties should be assessed in terms of potential
compaction. Too high a required compaction load may damage the GRP pipe.
d) Trench excavation – the trench sides should be stable under all working conditions. Excavated soil
material should not be placed near the edge of the trench. Ideally water should be removed from the
trench prior to pipe laying and backfilling.
e) The minimum width of the bottom of the trench for a single pipe should be a least 1.5 times the pipe
diameter. For multiple pipes, the distance between pipes should be at least 0.5 times the larger pipe
diameter and the gap between the outer pipe and the trench wall should be at least the same width as for
a single pipe.
f) Trench bottom – all rock, hard pan and sharp objects shall be removed.
g) Preparation of the trench – the bedding material on the trench bottom should be a least 100 mm thick and
provide the correct gradation and pipe support. All localised loading should be minimised e.g. through the
presence of other subsurface structures by providing at least a 300 mm bedding or compacted backfill
layer.
h) Placing and joining pipe – the GRP pipe shall be placed in the trench such that it is uniformly supported.
Extra backfill or bedding material should not be added or extra backfill forced in to provide this support.
All joints should be installed according to the manufacturer’s installation guideline.
i) Placing and compacting backfill materials – backfill materials should be placed around the GRP pipe such
that they will not disturb or damage the pipe. The backfill material should be worked into the underside of
the pipe before backfilling the trench
j) Compacting the backfill material – the backfill material should be compacted in the trench but it should be
ensured that the compacting loads will not damage the buried pipe. The minimum cover of backfill
material should be such that no damage to the buried pipe is caused by surface loads, e.g. vehicle
weight. Design guidance on burial depth is provided in AWWA M45 Chapter 5.7.3
k) Thrust blocks, if required, shall be capable of transferring the axial loads to the supporting structure
without causing overstress of the GRP pipe system.
Further guidance on GRP buried pipe installation is provided in AWWA M45 Chapter 6 and design of thrust
blocks in AWWA M45 Chapter 7.

5.5.6 Tolerances
Global tolerances shall be within 6 mm in all directions, unless otherwise shown on the approved drawings.
Dimensional tolerances for finished piping are given in Table 1. The dimension numbers are shown in Figure 1.
The acceptable tolerances for misalignment of flanges during installation are given in Table 2. It is common
practice for some flanges to be manufactured with bolt holes larger than the size of bolt being used with the
flange. Typically, the hole will be 3 mm larger. This should be taken into account when assessing the flange
misalignment tolerance in Tables 1 and 2.
