Seal stacks for sour service applications must resist hydrogen sulfide (H2S) and carbon dioxide (CO2) corrosion while maintaining mechanical integrity in aggressive environments. Sour service seal stacks utilize NACE MR0175-compliant materials preventing sulfide stress cracking and environmental degradation. Metal components use corrosion-resistant alloys while elastomers resist chemi... https://globalsealstech.com/product/seal-stack/
