50Packer element for downhole application
With the increasing demand of energy, oil and natural gas environment for well completion and production tools, the requirements of packer element are becoming higher and higher. Packer elements, commonly known as rubber bucket products on the market, has high toughness & cushioning characteristics and is used to protect the drilling pipeline from collision with the pipe wall. Packer element must be able to withstand very harsh environment and produce the required isolation in oil wells. When the packer element is made of the correct material and installed correctly, the tool shall achieve the best performance.
The exclusive manufacturing technology of extrusion and processing of JST packer elements greatly reduces the risk of hidden voids, streamline and gate extension, thus prolonging the service life of products and reducing expensive equipment downtime.

JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be PEEK, modified PTFE.
P seal is constructed from an elastomer with back up rings for anti-extrusion. Energized by the injection of sealant, it is a static seal that is used to seal rough casing and tubing. Backup rings are available in Mesh Stainless Steel or Solid Carbon Steel.
DKBI wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
JST's Inner and Outer BOP Seals could be made according to customer requirements. These seals are used in various type of Blow Out Preventors (BOP's).
Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.
ODU 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.
The FHB seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange internal face seal.
Back-up Ring/Anti Extrusion Rings is a ring that holds an elastomeric seal to its outline shape and in its right place. and are typically used with O Rings to eliminate extrusion at high pressures.
