S Type Ram BOP , Well Control Equipment , for Well Drilling Oilfield wellhead control
Description:
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.
