•Prerized components are forging matierals , having good strength and impact toughness , avoid the forging default.
•Middle flange uses combined seal, its switch is operated by hydraulicpressure, easy to change the ram.
•Ram rubber is abundant, and use self-contained seal.
•Equipped with auxiliary oil cylinder, compared with the traditional shear ram BOP.
•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.
•Manual locking device belongs to the standard configuration, In the event ofhydraulic loss , it can ensure that ram remains closed.
