Blowout Preventer Equipment SHENKAI Annular BOP Size 7" To 18-3/4"
Product Feature of Blowout Preventer Equipment
● 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.
● 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.
