API 16A Annular BOP Spherical packing element /Tapered Cameroon Packing Unit

API 16A Annular BOP Spherical packing element /Tapered Cameroon Packing Unit

Characters:

In the structure, it is divided into annular blowout preventer with spherical plastic core, annular blowout preventer with cone-shaped plastic core, and blowout preventer with tube-shaped plastic core. Annular BOP top cup and housing are connected by bolts or claw blocks.

Blowout preventer with spherical plastic core and dust-proof ring.

Performance characteristics: reasonable structure, easy operation, long life of plastic core, adapt to a wide range, capable to seal pipe string with nominal paths from 0-DN in ans shapes, better performance by combining with ran blowout preventer in the use.

Working Principle:

When wells must be sealed in case of kicks high pressure (10.5Mpa) oil from control systems enters into close-cavity under piston from housing oil outlet, to promote plastic core moving upward along ball surface, so that bearing tendons move closer to each other to moce the rubber between them to the center of wellhead so as to seal drilling tools or fully seal wellhead. In opening , hydraulic pressure oul enters into open-cavity above piston from housing oul inlet, to push piston moving downwards , so that plastic will reset with its own elasticity, wellhead will be open.

Our drilling BOP includes an annular BOP and a ram BOP. The annular BOP, consisting primarily of a shell, a header, a rubber core and a piston, and which by design is equipped with a hydraulic control system, can be used independently but usually operates in tandem with a ram BOP.
In accordance with API 16A requirements, the connections at the top and bottom of the rig are either flange or studded flange and can be conveniently connected to a drilling spool or ram BOP.
Our ram BOP features an advanced design that is nonetheless easy to operate.
The ram BOP is reliable, and spare parts can be easily replaced. As with the annular BOP, it can be used independently or coupled to other BOP combinations.
A hydraulic system can be used to open and close the ram, but should there be no power or air on site to run this system, the rams can be opened or closed manually.

Our BOP is packed in wood cases or pallets as per API standard or as customer's requirement. Professional packing and loading machines make products' quality & appearance free from damage.

Our company is located in Dongying, the entrance Yellow River into the sea also the base of Shengli Oilfield. It will takes only three hours to Qingdao Port. Great location achieves convenient transportation and logistics service.
