Oil & Gas

Selected grades of elastomers are specifically tailored to meet the challenges of the most inhospitable operating environments in the world, encountering explosive decompression, sour gas, extreme temperatures and aggressive chemicals. We supply components into a wide range of applications, including safety critical rubber/metal bonded blow-out preventor seals, low friction sampling cylinder seals and fully moulded O-rings up to 2 metres in diameter for use on pipe couplings and large pumps. We offer components with high sealing efficiency for systems operating in environments with high temperature combined with high pressure such as ultra-deep water drilling to 210 MPa (30,000 PSI) and 260°C. Our broad range of compounds allows our engineering teams to specify the right solution for every sealing system. Elastomers typically used in this industry include NBR, HBNR, fluoroelastomer (FKM - copolymers, terpolymers & tetrapolymers), Kemex™, Aflas® and perfluoroelastomer (FFKM). Explosive decompression (ED) resistant grades are available in Aflas®, FKM and HNBR.

Explosive Decompression Resistant

Permeation of a gas into an elastomer under high pressure may not result in any long term effect provided the pressure is released gradually, allowing the gas to permeate out of the elastomer. However, if the pressure is released rapidly, the pressurised gas can expand explosively, rupturing the elastomer in a catastrophic manner. We offer a number of materials which have been formulated to be resistant to explosive decompression including Aflas®, FKM and HNBR. We work with a laboratory which posses one of the most advanced explosive decompression testing units in Europe. Capable of testing seals of various geometries up to 10,000 psi, under varying compression, over any desired cycle/time within a temperature range from subzero up to +250°C. With pressure, temperature and pressure release cycles simulating actual field operation, independent testing can be carried out to confirm the performance of seal types and grades before installation.

Gas Specification Materials

Materials formulated in accordance with British Standard BS2494 (type ‘G’) are suitable for gas applications in the United Kingdom. The British Gas Specification BGC/PS/LC6 sets out the physical properties and quality requirements for seals and gaskets used in gas applications. We offer a range of nitrile (NBR) grades which are formulated in accordance with this specification.
