Description
Drilling BOP is mainly used to control well pressure by quick well shut in case of overflow and well kick to prevent blowout. 
           
Features

U-shape Dual Ram BOP

• Pressure containing parts are forgings, providing excellent strength and impact ductility.
• A large inventory of ram rubber which can seal by itself. 
• Areas exposed to fluids are welded with high nickel-based alloy for sour service.

 
Annular BOP

• Pressure containing parts are forged from premium alloy steel, providing excellent strength and impact ductility.
• A large inventory of ram rubber, low frictional resistance during open/close, help to seal the well under pressure.
• Packing is interchangeable with BOP of the same model abroad.
