HPHT Seals Azerbaijan | Strong Chemical Resistance
https://globalsealstech.com/hpht-seals-azerbaijan/
HPHT seals used in subsea production equipment across Azerbaijan's Caspian Sea fields must also withstand external hydrostatic pressure from the surrounding seawater in addition to internal well pressure. This dual-pressure environment requires careful engineering to ensure the seal performs reliably regardless of which direction the pressure differential is currently acting upon the component
