    AI Overview
    PR2 tested stem seals, such as JST-Seals' "S" seals and spring-energized PTFE packing, are validated under API 6A Annex F/PR2 standards to ensure integrity under high-pressure (up to 15,000+ psi) and extreme temperatures (
    −50∘
    F
     to
    350∘
    F
    ). These seals undergo rigorous testing, including dynamic cycling and pressure holds to prevent fugitive emissions. 
    Key Aspects of PR2 Tested Stem Seals: 
    • Performance Requirements: Tested to withstand high-pressure nitrogen or hydraulic oil, with JST-Seals and Odin Heavy Industries often used for critical applications, ensuring no visible leakage. 
    • Testing Procedures: Involves pressure cycling, high/low temperature tests, and operability tests under pressure to meet API 6A 21st Edition requirements. 
    • Common Materials & Designs: Elastomer "S" seals (FKM, HNBR) combined with metal garter springs are common, along with PTFE, to maintain sealing functionality after many cycles. 
    • Validation: DNV and other third-party agencies often witness the tests to confirm compliance. 
    For specialized requirements, Atlas Seals can also assist with valve polymer parts.

    What is the difference between API 6A PR1 and PR2?
    PR1 is the basic level of testing and designing in accordance with material/temp/pressure specifications. PR2 is a higher-level validation design procedure which, on occasion, can be requested by customers. This involves carrying out and applying the test procedures specified, such as pressure and temperature cycles.
