Adjustable Bore Ram for Blowout Preventer Systems

Variable diameter gate   Variable diameter gate is a highly functional core sealing component in gate blowout preventers, widely used in various well control operations such as oil and gas drilling, exploration and repair, and wellhead rescue. It is an important accessory for simplifying construction processes and improving wellhead operation efficiency. This variable diameter gate adopts a metal skeleton and rubber composite structure, relying on internal special mechanical design, and can dynamically adjust the sealing diameter. A single set of gate can adapt to various specifications of drill rods and pipe columns, without the need for frequent disassembly and replacement of gate according to the pipe diameter, greatly reducing construction downtime and effectively simplifying the wellhead operation process. The product has been optimized and upgraded in terms of sealing structure, with even compression force and stable sealing effect under high pressure conditions. It firmly seals…
