API 16A Standard Annular BOP Packing Element For Oilfield
All BOP can be utilized in place of Shaffer, Cameron, or Hydril ram BOP because they are all rigorously made in accordance with API Spec 16A.
The hydraulic BOP ram operates by applying hydraulic pressure to both open and close. The ram can be manually closed in the absence of electricity. The ram needs to be manually locked when the well needs to be closed for an extended amount of time. The hydraulic ram BOP has two uses: it can be utilized alone or in conjunction with other BOP.
With its assortment of pipe rams, the hydraulic ram BOP is capable of sealing not only the hollow well without pipe string but also the annular space between the casing and drilling equipment.
