Description
API 16A Ram BOP Blowout Preventer for Oilfield Well Control
API 16A Ram BOP for Drilling, Workover and Surface Well Control
An API 16A Ram BOP Blowout Preventer helps operators close the wellbore and control well pressure during drilling, workover, well testing, completion and intervention operations. In a surface well control system, it works as a key pressure barrier between the wellbore and the rig floor equipment.
The equipment uses two opposed ram blocks that move toward the center of the bore. Depending on the selected ram type, the unit can seal around drill pipe, tubing, casing or work string, close an open bore, or shear suitable tubulars during emergency well control. When the pipe size, pressure rating and ram configuration match the well program, a ram-type BOP provides direct closing movement and reliable pressure containment.
Buyers may also describe this equipment as API 16A BOP, API Spec 16A Ram BOP, API 16A blowout preventer, Ram Blowout Preventer, RAM BOP, Ram Type BOP, BOP Ram Preventer, Surface Ram BOP, Drilling Ram BOP, Workover BOP, Oilfield Ram BOP, FZ Ram BOP, 2FZ Double Ram BOP, Pipe Ram BOP, Blind Ram BOP, Shear Ram BOP or Blind Shear Ram BOP.
Although these terms usually refer to the same product family, the final configuration must follow the actual BOP stack and well control requirement.

What Is a Ram BOP Blowout Preventer?
A Ram BOP Blowout Preventer is a well control device installed on a wellhead, drilling BOP stack, workover stack or well testing pressure control package. It contains two opposite ram assemblies. When the BOP control unit sends hydraulic pressure to the closing chamber, the ram blocks move inward and create a pressure seal.
Each ram type has a specific function. Pipe rams seal around a selected tubular outside diameter, while blind rams close the bore when no pipe remains in the hole. Shear rams cut suitable tubulars under the correct operating conditions, and blind shear rams can cut pipe and close the wellbore in one emergency sequence.
A complete surface BOP stack often combines several ram cavities to cover drilling, tripping, well testing, workover, completion and emergency shut-in requirements. Compared with an annular BOP, a ram-type preventer usually provides a stronger seal on a specific pipe size. For that reason, it gives the operator a clear ram selection for different well control scenarios.

Ram Types Available
Pipe Rams
Pipe rams seal around a specific pipe outside diameter. They work well when the drilling string, tubing, casing or work string size is clear in the well program. Therefore, the pipe ram size should match the tubular OD and operating condition.
Before production, customers should confirm pipe OD, connection type, tool joint size and required sealing range. If the pipe size changes during drilling or workover, the operator may need to replace the ram assembly to maintain proper sealing performance.
Blind Rams
Blind rams close the bore when no pipe remains in the hole. Because of this, they provide a direct shut-in barrier during drilling, well testing, workover or completion operations. Operators usually select blind rams as a backup closure option for open-hole well control.
Shear Rams
Shear rams cut suitable tubulars during emergency well control operations. However, a shear ram BOP does not simply close around pipe. Instead, it must match the pipe size, pipe grade, wall thickness, hydraulic system and accumulator capacity. For this reason, the selection process should include full tubular data and operating conditions.
Blind Shear Rams
Blind shear rams can shear suitable tubulars and close the bore under proper operating conditions. In emergency well control, they support the operation when the crew must cut the string and shut in the well.
However, shear capability depends on pipe size, grade, wall thickness, tool joint position, hydraulic pressure, accumulator capacity and ram design. For this reason, full tubular data should be confirmed before selecting a shear ram BOP or blind shear ram assembly.
Variable Bore Rams
Some drilling and workover programs require sealing flexibility across a range of pipe sizes. In this case, customers can discuss variable bore ram options. This option may reduce frequent ram replacement when the well program uses several tubular sizes.
Ram Type Selection Guide
| Ram Type | Main Function | Typical Buyer Requirement |
| Pipe Ram | Seals around a fixed pipe OD | Drill pipe, tubing, casing or work string sealing |
| Blind Ram | Closes open bore without pipe | Open-hole closure and backup barrier |
| Shear Ram | Cuts suitable tubulars | Emergency pipe cutting requirement |
| Blind Shear Ram | Cuts pipe and closes bore | Emergency shut-in and wellbore isolation |
| Variable Bore Ram | Seals a pipe size range | Multi-size drilling or workover program |
Why Choose a Double Ram BOP?
A Double Ram BOP combines two ram cavities in one body. Compared with two separate single ram bodies, this design saves stack height and gives the operator more control options in a compact layout.
A common arrangement uses one pipe ram cavity and one blind ram cavity. Another arrangement uses one pipe ram cavity and one blind shear ram cavity. In drilling BOP stacks, this equipment often works with annular BOPs, drilling spools, choke lines, kill lines, BOP control units and wellhead equipment to form a complete well control barrier system.
For this reason, oilfield buyers often choose a double ram configuration when they need a compact drilling or workover BOP stack, two sealing functions in one body, a pipe ram and blind ram combination, a pipe ram and blind shear ram combination, reduced stack height, replacement equipment for an existing surface stack, or better choke line and kill line connection planning.
The best cavity arrangement should be confirmed after reviewing the drilling program, workover requirement, wellhead connection or stack drawing.
Oilfield Applications
SGPE Ram BOP equipment supports upstream oil and gas operations where pressure containment, fast shut-in performance and reliable well control are critical. It can be used in land drilling rig BOP stacks, offshore drilling BOP systems, workover rig pressure control stacks and well testing pressure control packages.
In addition, the equipment is suitable for surface BOP stacks used in drilling and completion operations, wellhead pressure control systems for oil and gas wells, snubbing unit pressure control systems, and coiled tubing well intervention support packages. It can also be selected for choke line and kill line connection layouts where the BOP stack must match the wellhead, drilling spool, adapter spool or other pressure control equipment.
For high-pressure oil wells, gas wells and sour service wells with H2S risk, the selected Ram BOP must match the required bore size, working pressure, ram configuration, connection type and service condition. It can also support rig upgrade projects, BOP replacement projects, oilfield service company rental fleets, well control equipment maintenance bases, and drilling contractor spare BOP or emergency replacement programs.
In these field conditions, the preventer must close smoothly, hold pressure safely and help the operator restore well control quickly. Therefore, correct model selection matters as much as manufacturing quality, especially when the project involves high pressure, sour service, shear ram requirements or replacement for an existing BOP stack.
How to Select the Correct Ram BOP
A quotation should not rely only on bore size and pressure rating. Instead, the selected equipment must match the stack layout, well program, tubular data and operating condition. This review helps avoid wrong ram size, wrong connection type, mismatched side outlet or insufficient shear capacity.

FAQ About API 16A Ram BOP Blowout Preventers
1. What is the main function of an API 16A Ram BOP Blowout Preventer?
An API 16A Ram BOP Blowout Preventer helps the operator control well pressure by closing the wellbore with two opposed ram blocks. Depending on the selected ram type, it can seal around drill pipe, tubing or casing, close an open bore, or shear suitable tubulars during emergency well control.
In drilling, workover, well testing and completion operations, the unit works as a key pressure control barrier in the surface BOP stack. Therefore, it helps the crew shut in the well when kick flow, formation pressure or abnormal conditions appear.
2. What is the difference between a Single Ram BOP and a Double Ram BOP?
A Single Ram BOP has one ram cavity in the body. The operator can configure this cavity with pipe rams, blind rams or shear rams according to the well control requirement. It works well when the stack design needs one sealing function in a compact body.
A Double Ram BOP has two ram cavities in one body. This design gives the operator two sealing functions without adding another separate unit. For example, many drilling BOP stacks use one pipe ram cavity and one blind ram cavity, while some projects use one pipe ram cavity and one blind shear ram cavity.
3. What ram types can SGPE provide for this product?
SGPE can provide pipe rams, blind rams, shear rams and blind shear rams for API 16A well control equipment. Pipe rams seal around a specific drill pipe, tubing, casing or work string OD, while blind rams close the bore when no pipe remains in the hole.
In addition, shear rams cut suitable tubulars, and blind shear rams can shear and close the wellbore under proper operating conditions. For accurate selection, please share pipe size, pipe grade, wall thickness, tool joint information and operating pressure.
4. Can a Ram BOP shear drill pipe?
Yes, but only when the equipment uses a suitable shear ram or blind shear ram design. A standard pipe ram or blind ram cannot shear drill pipe. Shear performance depends on drill pipe OD, pipe grade, wall thickness, tool joint position, hydraulic pressure, accumulator capacity and ram design.
Because of this, buyers should confirm the full tubular specification before selecting a shear ram BOP. Useful information includes drill pipe size, material grade, weight per foot, connection type and maximum expected operating condition.
5. How do I choose pipe rams for a Ram BOP?
To choose pipe rams correctly, first confirm the exact tubular outside diameter. Pipe rams normally seal around one specific size, such as drill pipe, tubing, casing or work string OD. Then check the tool joint size, connection type, well program and operating condition.
These details help avoid ram mismatch during drilling, workover or well testing operations. When sending an RFQ for a pipe ram BOP, please include pipe OD, tubular type, tool joint OD, pressure rating and BOP model.
6. What are FZ Ram BOP and 2FZ Ram BOP?
FZ usually refers to a single ram BOP model direction, while 2FZ usually refers to a double ram BOP model direction. In simple terms, FZ has one ram cavity, and 2FZ has two ram cavities.
For example, a customer may ask for an FZ Ram BOP for one pipe ram position. In comparison, another customer may choose a 2FZ Double Ram BOP for one pipe ram and one blind ram, or one pipe ram and one blind shear ram. The suitable configuration depends on bore size, pressure rating, stack drawing and field requirement.
7. What bore sizes are available from SGPE?
SGPE can offer common bore sizes such as 7-1/16 inch, 9 inch, 11 inch, 13-5/8 inch, 16-3/4 inch, 18-3/4 inch, 20-3/4 inch, 21-1/4 inch and 26-3/4 inch. These sizes cover many drilling, workover, well testing and surface pressure control applications.
Common buyer searches include 7-1/16 inch 10K Ram BOP, 11 inch 10K Double Ram BOP, 13-5/8 inch 5K Ram BOP, 13-5/8 inch 10K Ram BOP and 18-3/4 inch Shear Ram BOP. However, final selection should also confirm working pressure, connection type, ram configuration, side outlet requirement and BOP stack layout.
8. What working pressure ratings can SGPE supply?
SGPE can supply common pressure ratings such as 2,000 psi, 3,000 psi, 5,000 psi and 10,000 psi. However, the final pressure class depends on bore size, body design, connection type, ram function and project specification.
For many drilling and workover projects, buyers search for 3K Ram BOP, 5K Ram BOP, 10K Ram BOP, 13-5/8 inch 5K Ram BOP or 11 inch 10K Ram BOP. These keywords usually point to specific BOP stack requirements.
9. Can SGPE provide Ram BOP for sour service and H2S wells?
Yes. SGPE can provide equipment for sour service when the oil and gas project requires H2S resistance. In this case, wetted parts need suitable material selection, hardness control and inspection support according to project requirements such as NACE MR0175 / ISO 15156.
For sour oil wells, sour gas wells or high-H2S well control projects, buyers should share H2S content, CO2 content, chloride level, temperature, pressure, fluid condition and required material class. These details help confirm the material plan, sealing elements and inspection requirements.
10. What end connections and side outlets can this equipment have?
The body can use flanged, studded, studded × flanged or flanged × flanged end connections according to the BOP stack design. The correct top and bottom connection helps the unit match the annular BOP, drilling spool, wellhead, adapter spool or other pressure control equipment.
Side outlets can support choke line, kill line or other stack connection requirements. Before quotation, please confirm side outlet size, pressure rating and connection type. For replacement projects, a stack drawing, old nameplate photo or flange specification can help avoid mismatch.
