AF800 Range of Peek Materials for Oil and GasIndustry Utilising Genuine Victrex Peek PolymersIn most applications, it is a combination of three or more of these properties that dictates the use of AF800Peek Materials: High temperature resistanceGood electrical propertiesVery low creepHigh dynamic fatigueInsensitive to Rapid Gas Decompression (RGD)Excellent hydrolysis resistance High wear resistanceHigh erosion resistanceEase of processing and machiningExcellent chemical resistanceHigh mechanical strengthComparison with Other Thermoplastic Polymers used in Offshore and Onshore ServiceHDPEPA11PVDFPPSAF801 PEEK S.G.0.95–0.981.031.781.361.32Melting point ( 1000300–1300800–200032004100Tensile strength (MPa)20–3025–3037–4870105Shore D hardness55–7032–6175–779399(Rockwell M)Deflection temp at 264psiFlexural modulus (MPa)AF800 PEEK materials are used in a wide range of oil and gas applications due to the unique combinationof properties and range of compounds and unfilled polymersTypical applications: Logging toolsSeals and backup ringsConnectorsCompressor componentsPumps (surface and submersible) Plugs and packersCompositesCables and wirelineTubes and pipesInsulating components

Seals, Back-up Rings and PackingsEffective sealing throughout the oil production process is needed for differential pressures of up to 20,000 psi.Typical sealing materials such as elastomers and fluoropolymers display: good temperature and chemical resistance poor mechanical properties suffer high levels of creep (extrusion)The advantages of AF800 PEEK materials It has the right combination of properties to be used as a back-up ring or packing to the PTFE/elastomerseal:–– high temperature resistance–– chemically resistant–– mechanical barrier to ‘extrusion’AF800 PEEK can also be used itself as a direct sealing material AF800 ductility offers advantages in assembly as the seals are often scarf cut to allow the ring to beopened and clipped around the fitting High performance, spring energised seals PEEK is used for support, non-extrusion and sealing elements where pressures may exceed 1035 barat temperatures up to 230 C Seal assemblies utilised in various valves and chokes as stem packing or face seals and are used tocontain high pressure production fluids (and gas) at the wellheadDown Hole Electrical Connectors One of the most important parts of any drilling/production system is the transmission of both power anddata between the operating environment and the surface, this is achieved through systems of connectors Connectors must be insulated with a material capable of running at temperatures up to 200 C, in veryaggressive chemical environments and at a differential pressure of 20,000 psi without suffering from‘extrusion’ and loss of electrical properties Historically made from glass, ceramic or metal composite which gives:–– assembly problems–– different materials give problems with jointing and differential thermal expansion–– high tooling costs/design modifications very costly
