SR-BOP1821D Hydraulic Double-ram Blowout Preventer

The blowout preventer is a key part of the well control device. It is mainly used for midway testing of drilling, oil production, oil testing, and downhole operations of new well perforation. It controls wellhead pressure during operations to effectively prevent blowout accidents, achieve safe construction and avoid environmental pollution. Installing a hydraulic blowout preventer can not only shorten the time for sealing the oil pipe, but also greatly improve the work efficiency.
