1.1 S Type Ram BOP Structual Feature：
● Pressurized components adopts superior alloy steel with good strength and impact toughness.
● Door seal of the high pressure BOP uses combined seal, which has better seal from the well pressure.
● Use floating or integral gate, can seal safely and change conveniently.
● Use buriel-type oil passage, Bearing hinge is separated from the hydraulic hinge.
● Hinge structure is simple, easy to dismount and mount.
● Use big arc-type shell on both sides of the chamber, and transit by arc-type all around, to reduce the peak stress of the shell under pressure.
● With compact structure, smaller than similar foreign products.
● The internal shell of BOP resistant to low temperature can process pipeline, to make the steam flow inside the BOP, radiat heat.

2.1 Annular BOP 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.
