Engineers say seals made with Parker Hannifin's carboxylated HNBR sealing material operate better in extremely high temperatures and with highly abrasive fluids than other nitriles. A Canadian oil-well tooling company is using the material as the packing element around casing and piping in oil wells. The well fluids are corrosive and eat the casings, experts say. Plus, the farther into the well hole the tools go, the higher the temperatures they meet. The holes can go down to 10,000 ft. The XHBNR works in temperatures up to 300F and has a tensile strength of 5000 psi. It also resists hydrogen sulfide.
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
