RONGSHENG 11 Inch Annular BOP Blowout Preventer 3000 PSI Equipment
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.
