  • API 16D Certified BOP Closing Unit

    API 16D Certified BOP Closing Unit

    A BOP accumulator unit (also known as a BOP closing unit) is one of the most critical components of blowout preventers. Accumulators are placed in hydraulic systems for the purpose of storing energy to be released and transferred throughout the system when it is needed to accomplish specific operations. BOP accumulator units also provide hydraulic support when pressure fluctuations occur. These fluctuations happen often in positive displacement pumps due to their operational functions of trapping and displacing fluid.

  • API 16 RCD Certified Rotary Preventer

    API 16 RCD Certified Rotary Preventer

    The rotary blowout preventer is installed on top of the annular BOP. During underbalanced drilling operations and other pressure drilling operations, it serves the purpose of diverting flow by sealing the rotating drill string. When used in conjunction with drilling BOP, drill string check valves, oil-gas separators, and snubbing units, it allows for safe pressurized drilling and snubbing operations. It plays a vital role in special operations such as liberating low-pressure oil and gas layers, leak-proof drilling, air drilling, and snubbing well repairs.

  • Shaffer Type BOP part shear ram assembly

    Shaffer Type BOP part shear ram assembly

    · In accordance with API Spec.16A

    · All the parts are original or interchangeable

    · Reasonable structure, easy operation, long life of core

    · Adapt to a wide range, capable of sealing pipe string with nominal path shapes, better performance by combining with ram blowout preventer in the use.

    A shear ram can cut pipe in the well, blindly close the wellhead, and also be used as a blind ram when there is no pipe in the well. The installation of the shear ram is the same as the original ram.

  • Shaffer Type Variable Bore Ram Assembly

    Shaffer Type Variable Bore Ram Assembly

    Our VBR rams are suitable for H2S service per NACE MR-01-75.

    100% interchangeable with type U BOP
