The high performance elastomer-to-metal bonded sealing elements provide the high level of extrusion resistance necessary for high pressure and temperature casing and tubing hanger applications. Combining the range of Trelleborg’s proprietary XploR Rapid Gas Decompression (RGD) and sour gas resistant elastomers with corrosion resistant metal end caps, Trelleborg Sealing Solutions engineers can design a customized sealing solution to meet specific oil field requirements.
Sealing in the elastomer-to-metal design solution is achieved by controlled deformation of the elastomer and metal end cap elements during installation and operation. Optimal stress distribution throughout the elastomer body is modelled through Finite Element Analysis (FEA) to ensure appropriate design standards are applied to each customer’s unique application. Extrusion resistance is provided by the specially designed metal end caps that provide positive metal-to-metal sealing interference with the hardware upon assembly and conform to any potential extrusion gaps under pressure.
