PEEK seal stacks excel in HPHT wells with temperatures to 600°F and pressures over 20,000 psi. Thermoplastic PEEK offers chemical resistance to H2S and CO2. Spring-energized PEEK seals maintain contact in thermal cycling. Backup rings prevent extrusion in clearance gaps. Low creep properties ensure long-term sealing. CNC machining achieves micron-level precision. Stacks integrate into... https://globalsealstech.com/media/
