SIST EN ISO 14692-4:2017 PDF

Overview

EN ISO 14692-4:2017 / ISO 14692-4:2017 specifies requirements and recommendations for the fabrication, installation, inspection and maintenance of GRP piping systems (glass-reinforced plastics) used in the petroleum and natural gas industries. It covers the lifecycle stages from delivery and handling through installation, system pressure testing, operation, maintenance and repair. This part is intended to be read in conjunction with ISO 14692‑1 (design) and is published by CEN as the European adoption of the ISO document.

Key topics and requirements

The standard provides practical, normative and informative guidance across fabrication and operational activities, including:

• Delivery, inspection and documentation requirements for GRP piping components and spools.
• Handling and storage best practices to avoid damage prior to installation.
• Installer qualifications and minimum training requirements for bonders, pipe fitters, spool builders, supervisors and inspectors (see Annex C).
• Installation procedures covering cutting, jointing methods, supports for above-ground piping, buried piping considerations and tolerances.
• Jointing methods and guidance for on-site fabrication (Annex D includes jointing guidance).
• System testing procedures including flushing and pressure testing and associated certification.
• Inspection and Non-Destructive Examination (NDE) guidance to verify integrity and quality (informative Annex F).
• Maintenance, repair and modification procedures: replacement, temporary repairs, tie-ins and re-certification after works.
• Electrical conductivity, electrostatic dissipative properties and earthing requirements (normative Annex E).
• Quality programmes and documentation for installation, testing and ongoing maintenance.
• Normative annexes with defect types, acceptance criteria and handling/storage checklists.

Practical applications

EN ISO 14692-4:2017 is applicable to GRP piping systems in:

• Onshore and offshore oil & gas processing facilities
• Utility service piping within petroleum and natural gas installations
• Chemical service lines within hydrocarbon processing plants (where GRP is specified)

The standard helps ensure safe, durable and compliant GRP piping installations that meet industry expectations for performance and maintainability.

Who should use this standard

• Design engineers and specifiers working with GRP piping in oil & gas projects
• Fabricators, spool-builders and on-site installers of GRP systems
• Commissioning teams responsible for flushing and pressure testing
• Maintenance teams, plant operators and asset owners overseeing inspection and repair
• QA/QC and inspection personnel, and regulatory/compliance auditors
