ISO 14692

Covers — GRP (glass-reinforced plastic/FRP) piping systems for petroleum and natural gas: vocabulary and materials (Part 1), qualification and manufacture (Part 2), system design (Part 3), and fabrication, installation, and operation (Part 4), including above-ground and buried GRP.

Does NOT cover (exclusions) — the following are governed elsewhere:

• GRP water pressure pipe for waterworks → AWWA C950.
• Filament-wound RTR/FRP pressure pipe (general) → ASTM D2996.
• Metallic piping → the applicable B31 code.

ISO 14692 is the oil-and-gas GRP standard; waterworks GRP uses AWWA C950.

ISO 14692 sets minimum requirements for GRP piping:

• Qualification — qualified component performance envelopes (pressure/temperature/axial) from testing.
• System Design — stress analysis using GRP's anisotropic, envelope-based allowables (not isotropic steel rules).
• Fabrication & Jointing — adhesive-bonded, laminated, or mechanical joints made by qualified procedures.
• Installation & Operation — support, fire/blast considerations, and operating limits.

ISO 14692 is the oil-and-gas standard for glass-reinforced plastic (GRP/FRP) piping, covering qualification, manufacture, system design, and installation across its parts. GRP is widely used offshore — firewater, produced water, cooling, and drains — for its corrosion resistance and low weight.

Crucially, GRP is anisotropic and does not obey isotropic-steel design rules: system design uses qualified performance envelopes and specific stress-analysis methods, and jointing (adhesive/laminated) and fire/blast performance demand qualified procedures. The 2017 edition added provisions for buried GRP.

Engineering Note: Do not analyze GRP piping with steel-pipe assumptions — use ISO 14692's qualified envelopes and account for the low axial stiffness and thermal-expansion behavior, which drive very different support and flexibility solutions than steel.
