This part of ISO 13628 defines the technical requirements for safe, dimensionally and functionally interchangeable flexible pipes that are designed and manufactured to uniform standards and criteria. Minimum requirements are specified for the design, material selection, manufacture, testing, marking and packaging of flexible pipes, with reference to existing codes and standards where applicable. See ISO 13628-11 for guidelines on the use of flexible pipes and ancillary components. This part of ISO 13628 applies to unbonded flexible pipe assemblies, consisting of segments of flexible pipe body with end fittings attached to both ends. This part of ISO 13628 does not cover flexible pipes of bonded structure. This part of ISO 13628 does not apply to flexible pipe ancillary components. Guidelines for bend stiffeners and bend restrictors are given in Annex B.

ISO 13628-2:2006(E)
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.
ISO 13628-2 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and production
equipment.
This second edition cancels and replaces the first edition (ISO 13628-2:2000), which has been technically
revised.
ISO 13628 consists of the following parts, under the general title Petroleum and natural gas industries —
Design and operation of subsea production systems:
⎯ Part 1: General requirements and recommendations
⎯ Part 2: Unbonded flexible pipe systems for subsea and marine applications
⎯ Part 3: Through flowline (TFL) systems
⎯ Part 4: Subsea wellhead and tree equipment
⎯ Part 5: Subsea umbilicals

⎯ Part 10: Specification for bonded flexible pipe
⎯ Part 11: Flexible pipe systems for subsea and marine applications
The following parts are under development:
⎯ Part 12 dealing with dynamic production risers
⎯ Part 13 dealing with remotely operated tools and interfaces on subsea production systems

ISO 13628-2:2006(E)
Introduction
This part of ISO 13628 is based on API Specification 17J, Specification for unbonded flexible pipe, Second
edition, November 1999, and the Amendment issued June 2002. This part of ISO 13628 has been technically
revised and updated to cater to the needs of the international oil and natural gas industries.
Users of this part of ISO 13628 should be aware that further or differing requirements might be needed for
individual applications. This part of ISO 13628 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 13628 and provide details.

Part 2:
Unbonded flexible pipe systems for subsea and marine
applications
1 Scope
This part of ISO 13628 defines the technical requirements for safe, dimensionally and functionally
interchangeable flexible pipes that are designed and manufactured to uniform standards and criteria. Minimum
requirements are specified for the design, material selection, manufacture, testing, marking and packaging of
flexible pipes, with reference to existing codes and standards where applicable. See ISO 13628-11 for
guidelines on the use of flexible pipes and ancillary components.
This part of ISO 13628 applies to unbonded flexible pipe assemblies, consisting of segments of flexible pipe
body with end fittings attached to both ends. This part of ISO 13628 does not cover flexible pipes of bonded
structure. This part of ISO 13628 does not apply to flexible pipe ancillary components. Guidelines for bend
stiffeners and bend restrictors are given in Annex B.
NOTE 1 Guidelines for other components are given in ISO 13628-11.
This part of ISO 13628 does not apply to flexible pipes that include non-metallic tensile armour wires. Pipes of
such construction are considered as prototype products subject to qualification testing.
The applications addressed by this part of ISO 13628 are sweet and sour service production, including export
and injection applications. Production products include oil, gas, water and injection chemicals. This part of
ISO 13628 applies to both static and dynamic flexible pipes used as flowlines, risers and jumpers. This part of
ISO 13628 does not apply to flexible pipes for use in choke-and-kill line applications.
NOTE 2 See API Specification 16C for choke-and-kill line applications.
NOTE 3 ISO 13628-10 provides guidelines for bonded flexible pipe.
