Structual Feature
Pressurized components are forging matierals, having good strength and impact toughness, avoid the forging default.
Middle flange uses combined seal, its switch is operated by hydraulic pressure, easy to change the ram.
Equipped with auxiliary oil cylinder, compared with the traditional shear ram BOP, it has the function, smaller volume.
Ram rubber is abundant, and use self-contained seal.
Manual locking device belongs to the standard configuration, In the event of hydraulic loss, it can ensure that ram remains closed.
Manual and hydraulic locking device and auxiliary oil cylinder can be equiped according to customer's requirements flexibly, and easy to interchange.
The internal shell of BOP resistant to low temperature can process pipeline, to make the steam flow inside the BOP, radiat heat. (for costumer's option).
The internal part of BOP resistant to high sulfer which contact the well liquid has Surfaced high nickel base alloy, which can achieve the highest levels of resistance to H2S and CO2.
