Overview
SIST EN ISO 14692-2:2017 (ISO 14692-2:2017) specifies requirements for the qualification and manufacture of glass‑reinforced plastics (GRP) piping and fittings used in the petroleum and natural gas industries. The standard enables purchasers to acquire GRP components with known and consistent properties from any source. It is intended to be read in conjunction with ISO 14692‑1 and covers qualification procedures, preferred dimensions, quality programmes, component marking and documentation.
Key topics and technical requirements
The standard addresses practical and technical elements needed to qualify and manufacture GRP piping systems:
-
Manufacturer’s declarations and qualification procedure
- Procedures for demonstrating material and product performance, including long‑term regression testing and generation of long‑term envelope data.
- Concepts such as MPR, gradients and partial factors for design lifetime, chemical degradation and cyclic loading.
-
Qualification programme
- Rules for scaling, product qualification, validation of long‑term envelopes, density and thermal expansion checks.
- Specific qualification routes for external pressure, elastic properties (axial, hoop and bending moduli), and Poisson’s ratios.
-
Manufacturing quality programme
- Mandatory quality control tests: mill hydrostatic tests for pipes and spoolpieces, degree of cure, Barcol hardness, glass content, visual inspection, key component dimensions and retest procedures.
- Optional tests: electrical conductivity per length, fire performance, residual styrene content and additional QC tests.
-
Production details and traceability
- Requirements for production processes, jointing instructions, component marking, handling, storage, transportation and documentation.
- Documentation requirements for enquiries, purchase orders, qualification reports and production quality control records.
Practical applications and who uses this standard
ISO 14692-2:2017 is a practical reference for professionals involved with GRP piping in oil, gas and related industries:
- GRP manufacturers and fabricators - to establish and maintain qualification and quality control programmes that demonstrate consistent product performance.
- Procurement and specifications engineers - to specify qualified GRP piping and fittings with traceable test evidence and consistent dimensions.
- Design and integrity engineers - to interpret long‑term envelopes, partial factors and elastic properties for system design and assessment.
- QA/QC personnel and inspectors - to implement mill tests, dimensional checks and documentation control.
- Operators and asset owners - to assure supply chain consistency for onshore and offshore GRP piping applications.
