Annular BOP for well drilling
Feature
● Rubber core store glue big quantity , small friction resistance, when switch pressure sealing ability.
● Using hemispherical head, no stress concentration phenomenon when under pressure, casing stress evenly, easy to tear open outfit.
● Piston stroke is short, low height, and set the wear ring.
● The lip seal, long service life.
● Low temperature processing annular blowout preventer shell diameter has a trough steam pipe, pipe ventilation with saturated vapor, round shell for heating.( For the customer to choose ).
● High sulfate-resistant blowout preventer internal all parts contact well liquid surfacing high nickel base alloy, can achieve the highest levels of resistance to effect such as H2S and CO2. For the customer to choose.
