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.

The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. The chevron seal stack material could be PEEK, modified PTFE and spring.
V-Packings are used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.
Swivel joint ball plug is working together with hammer union seals, to seal the balls of high pressure elbows and grease.
The ESA valve rubber seal is a type of Polypak, it combines a rubber o-ring type and a conventional lip type seal to produce a unique sealing device.
The FHB seal design of the spiral spring combined arc lip, and the pressure comes from the inside.
Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
JST manufactures well service plunger pump packings in a wide variety of materials to suit specific well conditions and operating parameters, they are available in a wide range of elastomeric materials and high performance resins, including NBR, HNBR, FKM, filled PTFE, fabric reinforced rubber. to suit specific well conditions, operating parameters, and fracturing fluids.
