BOP SEALS

Blowout Preventer (BOP) seals are critical elastomeric sealing elements used in ram‑type BOPs to contain wellbore pressure and prevent uncontrolled hydrocarbon release. These seals play a vital role in maintaining well control during drilling, completion, wireline, and intervention operations by providing reliable sealing under extreme pressure, temperature, and mechanical loads. 

Types 

  • Inner & Outer seals 
  • Pipe ram, Blind ram & Shear ram seals 
  • Bonnet seals 
  • VBR seals 

Material Options 

  • HNBR (Hydrogenated Nitrile) 
  • SULFANITE® Ultra – NACE TM0187 – 40% H2S 
  • THERMANITE® – High temperature steam application up-to 600 °F

Technical Details 

  • Designed specifically for ram‑type BOP configurations 
  • Pressure ratings: Up to 15,000 psi (depending on BOP design and seal type) 
  • Temperature range:  
  • Standard service: ‑40°C to +150 °C 
  • High‑temperature service: Up to 288 °C (material dependent) 
  • Excellent resistance to extrusion, tearing, and compression set 
  • Compatible with major OEM ram BOP designs 
  • Suitable for dynamic and static sealing conditions 
  • Proven performance in H₂S, CO₂, drilling fluids, and hydrocarbons 

Applications 

  • Drilling well control systems 
  • Completion and workover operations
