50HNBR S seal for downhole application
Wellhead is a key component of oil and gas infrastructure. Wellhead sealing materials need to withstand high pressure and high temperature.
S-seal is a compact one-piece seal design with anti extrusion elastomer with two molded anti extrusion springs at the outer edge. Its unique design integrates two non extrusion devices and a sealing element into an overall structure to provide two-way sealing. At the same time, combined with a simple symmetrical contour non extrusion device, headless coil springs are used on both sides of the seal, allowing a large extrusion gap to be bridged under high pressure. Non extruded equipment (when made of the following materials) limits metal seals to static applications. S seal is a preferred design which attack by oilfield media where an O ring cannot survive the maintenance-free life cycle of the equipment.
