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.
