● 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.
