API well control equipment shaffer or cameron annular BOP/blowout preventer
1.The pressure-bearing components are forged, so it has better strength and impact toughness;
2.Floating sealing is applied to the cylinder cover and the open/close of the cover is realized by hydraulic power, so it is quick and convenient for changing rams;
3.The auxiliary oil cylinder affords a smaller volume with same function;
4.The ram rubber has massive storage volume, and it adopts self-contained sealing;
5.The standard configuration includes a manual locking device, which ensures the ram is closed tightly in case there is a
hydraulic pressure loss;
6.Both the manual and hydraulic locking device and the auxiliary oil cylinder can be installed flexibly into different positions according to customers' requirements, and the installation positions can be changed easily.
The BOP major pressure-bearing parts are forged to enhance safety and reliability performance. The opening/closing of side door is in a form of linear motion and the hydraulic control assembly moves linearly along the open-close piston rod. The ram BOP is an important part of well control unit and it is mainly applied to control the wellhead pressure during drilling, workover, and oil testing operations to prevent blowout effectively to realize safe construction.
Product features:
1.Floating seal structure is applied between side door and body, which can strengthen sealing performance by
wellbore pressure, and reduce the pre-tightening force of side door bolts
2.Shear ram with full seal function, after finishing shearing operations, it can fully close the wellhead
3.In case of sealed condition, drilling fluid circulation, choking and blowout prevention, killing operations can be achieved by the manifolds connected with side outlet of the body
4.Shearing with pressure-in emergency situations, it can shear the drilling tools within wellbore pressure, and close the well
5.Pipe ram and variable bore ram can suspend drilling tool
