This document defines the applications, pressure rating methodology, the classification of the products according to application, type of joint and resin matrix and the limitations to both the materials of construction and the dimensions. It also lists the terms, definitions and symbols used and provides guidance in the use and interpretation of ISO14692‑2, ISO14692‑3 and ISO14692‑4.ISO14692(allparts) is applicable to GRP piping systems that 1) utilize joints that are capable of restraining axial thrust from internal pressure, temperature change and fluid hydrodynamic forces and 2) have a trapezoidal shape for its design envelope. It is primarily intended for offshore applications on both fixed and floating topsides facilities, but it can also be used for the specification, manufacture, testing and installation of GRP piping systems in other similar applications found onshore, e.g. produced-water, firewater systems and general industrial use.For floating installations, reference is made to the design, construction and certification standards for the hull or vessel, since these can allow alternative codes and standards for GRP piping associated with marine and/or ballast systems. However, it is recommended that ISO14692(allparts) be used for such applications to the maximum degree attainable.ISO14692(allparts) can also be used as the general basis for specification of pipe used for pump caissons, stilling tubes, I-tubes, seawater lift risers and other similar items.Typical oil and gas industry applications for the use of GRP piping and pipelines include those listed in Table 1.Table1Typical current and potential GRP piping oil and gas applicationsBallast waterHydrochloric acidBoiler feed waterInert gasBrineJet-A fuelCarbon Dioxide (CO2)Natural gasChlorine, gas, wetOilCondensate (water and gas)(Sour) Oil plus associated gasCooling water, sweet, brackish, seawaterPotable waterDemineralised waterProcess waterDiesel fuelProduced waterDrainsSeawaterEmulsions (water-oil-gas mixtures)Service waterFire water (ring main and wet or dry deluge)Sewer (grey and red)Formation waterSodium hydroxideFresh waterSodium hypochloriteFuelSour waterGas (methane, etc.)Unstabilized oilGlycolVentsHydrocarbon (with or without associated gas)WastewaterHydrogen chloride gas (HCl)Water disposalInjection waterNOTE Some applications, such as wet chlorine gas, hydrogen chloride gas, hydrochloric acid, sodium hydroxide and sodium hypochlorite, require a barrier liner and may require specific corrosion resistant resins.
