A Design Study in Steel Castings - Steel Plates in BOP Valve                                        
Blowout Preventer(BOP) - Application
  • A blowout preventer (BOP) is a high pressure safety valve system at the top of the well head which stops uncontrolled fluid/gas flow in the wellbore.
  • There are two types of BOP valves -- annular and ram.
    • One advantage the annular blowout preventer has over ram-type blowout preventers is the ability to seal on a variety of pipe sizes.
