API Bop Front Rubber Seal Top Rubber Seal RAM Seals
Product Description
The product can match and interchange with most of the domestic BOP manufactories, (such as Shanghai Shenkai, Huabei Rongsheng, Chuanyou Jingkong, Baoji Oil, Jiangsu Xinde, Jiangsu Sanyi, etc). Over the years of usage in the oil fields, it has been proved that all the technical requirements and performance of our products can reach the standards of Shaffer sealing elements for replacement.
It can be customized according to customers' specific requirements of temperature, pressure, and environmental conditions.

Characters of BOP spare parts:
The structure, it is divided into an annular blowout preventer with a spherical plastic core, an annular blowout preventer with a cone-shaped plastic core, and a blowout preventer with a tube-shaped plastic core. Annular BOP top cap and housing are connected by bolts or claw blocks.
Blowout preventer with a 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 and shapes, better performance by combining with ran blowout preventer in the use.
Working on BOP spare parts:
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 move the rubber between them to the center of wellhead so as to seal drilling tools or fully seal wellhead. In the opening, hydraulic pressure oil enters into open cavity above the piston from housing out inlet, to push the piston moving downwards, so that plastic will reset with its own elasticity, wellhead will be open.
