Full title and description

AS ISO 24817:2022 — Petroleum, petrochemical and natural gas industries — Composite repairs for pipework — Qualification and design, installation, testing and inspection. This Australian adoption identically reproduces ISO 24817:2017 and specifies requirements and recommendations for qualifying, designing, installing, testing and inspecting externally applied engineered composite repair systems for corroded or damaged pipework, pipelines, tanks and vessels in the petroleum, petrochemical and natural gas sectors (and related utility service applications).

Abstract

AS ISO 24817:2022 provides a system-level normative framework for the use of externally applied composite repair systems on metallic substrates. It covers repair feasibility, repair classification, design methods (including substrate load sharing and laminate-based approaches), performance qualification and re‑qualification, materials and interface tests, installation procedures and installer qualifications, inspection and testing (including allowable defects and remedial actions), maintenance and decommissioning. The standard aims to ensure repairs meet defined performance and safety objectives over a stated design life.

Scope

The standard applies to the external application of engineered composite repair systems to corroded or mechanically damaged metallic pipework, pipelines, tanks and vessels used in petroleum, petrochemical and natural gas industries. It specifies requirements and gives guidance for: assessing repair feasibility; selecting repair class and design lifetime; deriving design inputs; performance qualification and re‑qualification of repair systems; installation practice and installer competency; acceptance criteria for repairs; inspection, testing, maintenance and decommissioning of composite repairs. It excludes internal linings and wholly new fabricated composite pressure-containing pipework.

Key topics and requirements

• Repair feasibility assessment and required background data (original design, service history, operational conditions).
• Repair classification and definition of design lifetime and performance objectives (repair classes and limits).
• Design methodologies: substrate load-sharing, laminate allowable-strain approaches, and performance-test-based design for through-wall and non-through-wall defects.
• Qualification and re‑qualification of repair systems including representative coupon and survival testing, interface adhesion, environmental compatibility and degradation factors.
• Detailed installation requirements: storage, surface preparation, laminate lay-up, cure, work packs, method statements and installer/supervisor competency and certification.
• Testing and inspection: allowable repair defects, nondestructive inspection methods, periodic inspection, monitoring, remedial options and documentation of repair condition.
• Specific considerations for live repairs, fire performance, cyclic loading, cathodic disbondment, electrical conductivity and special defect types (dents, gouges, fretting, delamination).
• System testing, reporting templates, annexes with test methods and calculation procedures, and owner responsibilities for engineered composite repair programs.

Typical use and users

Main users include asset owners and operators in oil, gas and petrochemical facilities, integrity and reliability engineers, design and inspection contractors, composite repair system manufacturers and suppliers, installation contractors, certifying bodies and regulatory compliance teams. Typical applications are onshore and offshore pipework repairs, pipeline sleeves and localized repairs to tanks and vessels where a qualified composite repair is an alternative to replacement or welding repairs.

Related standards

Key related documents and standards typically referenced or used alongside AS ISO 24817:2022 include: ISO 24817 (the original international text), earlier ISO/TS 24817 editions, national/adopted versions (EN/BS/AS adoptions), test-method standards for composite materials and adhesives (relevant ISO and ASTM test methods used for tensile, shear, adhesion and environmental testing), and complementary pipeline/tank standards and integrity guidance used by operators. Users should consult industry-specific codes and local regulatory requirements where applicable.
