Annular BOP into spherical plastic cone rubber core and core structure based on two rubber core structure
A tapered annular BOP rubber core structural features :
⑴ rubber core and HTDRIL completely interchangeable .
⑵ in the original structure with increased abrasion protection, to prevent and improve the piston due to the partial load pull cylinder phenomena generated .
⑶ rings section enhancements can be used to lift the overall BOP stack .
⑷ using chi -block connection for easy removal and replacement of the rubber core .
