USED FOR:
(Parts 1–4) Petroleum and natural gas industries – Glass-reinforced plastics (GRP) piping
Specification, design, manufacture, and installation of GRP (fiberglass) piping. Firewater mains, seawater lift, produced water, ballast-adjacent systems, and general utility service, mostly offshore but also onshore.
RELATED STANDARDS:
- ASME NM.2 – Glass Fiber Reinforced Thermosetting Resin Piping Systems
- ASTM D2992 – Standard Practice for Obtaining Hydrostatic or Pressure Design Basis for Fiberglass Pipe
- API SPEC 15S – Spoolable Reinforced Plastic Line Pipe
- ISO 10639 – Buried GRP pipe systems
- Classification society rules (DNV, ABS, RINA, LR, etc..)
DIMENSIONAL RANGE:
ISO 14692 doesn’t set a flat diameter ceiling, instead it constrains pressure and diameter together through the pressure-diameter product, which must stay below 12.62 bar·m. In practice this means the allowable design pressure drops as diameter increases: a 16 bar system must stay below DN750, while a DN1200 line must be designed below roughly 10.5 bar. Any diameter/pressure combination is technically admissible as long as that product isn’t exceeded, a detail worth checking early when a large-bore, higher-pressure GRP line is on the table.
DESCRIPTION:
Four parts, meant to be read together: Part 1 (vocabulary, applications, materials, pressure-rating methodology), Part 2 (qualification and manufacture of pipe and fittings), Part 3 (system design, layout, hydraulics, fire endurance, static discharge), and Part 4 (fabrication, installation, and operation). We use this whenever GRP is on the material selection list for corrosion-sensitive services where carbon steel would need heavy corrosion allowance or coating
IMPORTANT NOTES:
It’s written primarily for offshore topside applications, but it’s also usable onshore. For GRP integrated into a ship’s or platform’s ballast/marine system, the standard itself recommends deferring to the hull/vessel certification body, while still using ISO 14692 “to the maximum degree attainable” as good practice a nuance worth mentioning early with the classification society.
