Description
API 16A Single Ram BOP Blowout Preventer for Oilfield Well Control
SGPE API 16A Single Ram BOP Blowout Preventer is a compact ram-type device for oilfield well control and pressure control. It helps rig crews close around drill pipe, tubing or casing, seal an open bore, or provide one dedicated emergency barrier in a surface BOP stack.
A single ram BOP has one ram cavity inside the body. This cavity can be equipped with pipe rams, blind rams, variable bore rams, shear rams or blind shear rams according to the operation plan. Because of this one-ram structure, the FZ Single Ram BOP is a practical choice when a BOP stack needs one clear sealing or shearing function without adding unnecessary height.
Buyers may also describe this product as API 16A Single Ram BOP, FZ Single Ram BOP, Single Ram Blowout Preventer, Oilfield Single Ram BOP, Drilling Ram BOP, Workover Ram BOP, Pipe Ram BOP, Blind Ram BOP, Shear Ram BOP and BOP Stack Ram Preventer.
For replacement projects, SGPE can review the old BOP nameplate, stack drawing, connection photos and ram requirements before quotation. This helps buyers avoid wrong connections, incorrect ram selection and stack height problems before production starts.

What Is a Single Ram BOP?
A Single Ram BOP is a blowout preventer with one set of ram blocks inside the BOP body. When the BOP control unit sends hydraulic pressure to the closing chamber, the ram blocks move toward the bore center. Then the selected ram type closes around the tubular, seals the open bore or cuts the tubular according to the BOP configuration.
Compared with a double ram BOP, a single ram BOP has a simpler body structure and lower stack height. It also makes ram replacement, seal inspection and routine maintenance easier. In many surface well control systems, it works together with an annular BOP, double ram BOP, drilling spool, adapter spool, choke manifold, kill manifold, casing head or wellhead connector.
Because of its compact design, a single ram preventer often works as one dedicated barrier in the stack. It gives the system a defined function, such as pipe sealing, blind sealing, variable bore sealing or emergency shearing support.
When to Choose a Single Ram BOP
A single ram BOP is suitable when the BOP stack needs one specific ram function and the project does not require two ram cavities in the same body. It is often selected for compact workover stacks, well testing packages, wellhead service operations, replacement projects and pressure control packages where stack height matters.
| Selection Scenario | Why a Single Ram BOP Fits |
| One ram function is required | The BOP can carry pipe ram, blind ram, variable bore ram or shear ram according to the job |
| Stack height is limited | The one-cavity body helps keep the stack more compact |
| Workover or testing package needs one barrier | The design provides a defined sealing or shearing function |
| Existing BOP needs replacement | The single ram structure can match old stack height and connection layout more easily |
| Maintenance access needs to stay simple | One ram cavity makes inspection and ram replacement more direct |
For drilling stacks that require two ram functions in one body, a double ram BOP may be more suitable. SGPE can review the stack layout and recommend the right BOP type according to the actual operation plan.
API 16A Single Ram BOP Blowout Preventer for Field Operations
Drilling and workover operations need reliable well control equipment because well conditions can change quickly. During drilling, the BOP stack helps control kicks, shut in the well and support circulation through choke and kill lines. During workover and completion, the BOP helps crews manage pressure while they run or pull tubing, casing, plugs, packers and downhole tools.
SGPE API 16A Single Ram BOP Blowout Preventer supports new BOP stacks, replacement BOP projects, wellhead service packages and pressure control equipment packages. In compact workover or testing stacks, the single ram design adds a useful barrier while keeping the stack arrangement simple.
Main Functions of SGPE Single Ram BOP
The selected ram assembly determines how the Single Ram BOP works in the field.
Pipe rams close around a specific drill pipe, tubing or casing size. They seal the annular space between the tubular and the BOP bore. This option suits drilling and workover jobs where the pipe size remains clear in the operation program.
Blind rams close and seal the bore when no pipe stays inside the BOP. Crews often use blind rams during open-bore wellhead work, BOP stack testing, pressure isolation and completion preparation.
Variable bore rams seal around a selected range of tubular sizes. They reduce ram changes when one job involves several drill pipe, tubing or casing sizes.
Shear rams or blind shear rams cut tubulars and help close the wellbore when the BOP body, ram assembly and hydraulic control system support the required shear capacity. SGPE checks pipe OD, pipe grade, wall thickness, tool joint details and available hydraulic pressure before confirming a shear ram BOP.

Ram Type Selection Guide
The ram type determines how the Single Ram BOP works in the stack. Buyers should select the ram according to the pipe condition, sealing purpose and emergency control requirement.
| Ram Type | Main Function | Typical Use | Key Information to Confirm |
| Pipe Ram | Seals around a fixed pipe OD | Drilling, workover, tubing and casing operations | Pipe OD, pipe type, working pressure |
| Blind Ram | Seals the open bore | Open-bore wellhead work, BOP testing and isolation | Bore size, pressure rating, closing requirement |
| Variable Bore Ram | Seals around a selected pipe size range | Jobs with several drill pipe or tubing sizes | Minimum and maximum pipe OD, pressure rating |
| Shear Ram | Cuts tubulars after engineering confirmation | Emergency well control planning | Pipe OD, grade, wall thickness, hydraulic pressure |
| Blind Shear Ram | Cuts pipe and helps seal the bore | Critical high-pressure applications | Shear condition, well pressure, hydraulic capacity |
API 16A Design and Manufacturing Standard
SGPE API 16A Single Ram BOP Blowout Preventer follows API Spec 16A requirements for blowout prevention equipment. SGPE controls the BOP body, bonnet, ram blocks, sealing parts, operating system and pressure-containing components through defined manufacturing and inspection steps.
Temperature class also matters during selection. For many conventional ratings below 15,000 psi, projects often use T-20/250. For 15,000 psi and higher pressure service, some specifications require T-75/250 or another agreed class. SGPE confirms the final temperature class according to the contract, elastomer selection, working pressure and fluid condition.
Technical Configuration Options
Different projects may require different body types, locking methods, connection arrangements and service conditions. SGPE reviews these details before quotation.
| Configuration Item | Available or Common Options | Selection Note |
| Body Type | Forged body, casting body | Forged body is recommended for high-pressure or stricter service |
| Locking Type | Manual locking, hydraulic locking | Confirm according to rig operation and control system requirement |
| Top Connection | Flanged, studded, clamp hub or customized | Must match the upper stack component |
| Bottom Connection | Flanged, studded, clamp hub or customized | Must match wellhead, spool or adapter |
| Side Outlet | Available according to model | Confirm size, pressure and connection type |
| Service Condition | Standard, sour service, H2S service | Sour service requires material and document review |
| Temperature Class | T-20/250, T-75/250 or project-specific | Confirm according to operating condition and contract requirement |
| Documentation | Standard or project-specific package | Confirm API, MTC, test report, ITP and third-party inspection needs |
Forged Body and Casting Body Options
SGPE mainly recommends forged body Single Ram BOPs for high-pressure drilling, sour service and stricter well control projects. Forged pressure-containing parts provide strong mechanical performance and better suitability for demanding field service.
Casting body options can work for selected standard applications after technical confirmation. Before recommending the final body type, SGPE checks pressure rating, service condition, inspection level and end-user specification.
For high-pressure BOP stack projects, H2S service, 10,000 psi service or 15,000 psi service, buyers should send the full technical specification. SGPE can then confirm material, body structure, seal system and document scope before quotation.
Ram Options for Oilfield Operations
Pipe Ram BOP
A pipe ram BOP closes around a defined pipe OD. It gives a reliable seal when drill pipe, tubing or casing stays in the wellbore. Buyers usually choose pipe rams for drilling, tubing workover, casing operations and well intervention jobs.
Blind Ram BOP
A blind ram BOP closes the open bore when no pipe passes through the BOP. Crews use blind rams during BOP stack testing, wellhead isolation, completion preparation and open-bore pressure control procedures.
Blind rams should not close on pipe unless the BOP uses a blind shear ram design. Therefore, buyers should confirm the actual field function before ordering.
Variable Bore Ram BOP
A variable bore ram BOP seals around a range of pipe sizes. This option helps reduce ram changes when the job involves different drill pipe, tubing or casing ODs.
However, the buyer still needs to confirm the pipe size range, pressure rating, sealing requirement and service condition. SGPE can review the operation program and recommend a suitable ram range.
Shear Ram BOP
A shear ram BOP cuts tubulars and helps seal the wellbore during emergency well control situations. This option requires careful engineering review.
SGPE must check pipe OD, pipe grade, wall thickness, tool joint limitation, available hydraulic pressure and expected shear condition before confirming the final proposal.
Oilfield Applications
SGPE API 16A Single Ram BOP Blowout Preventer mainly serves surface well control and pressure control environments.
| Application | How the Single Ram BOP Supports the Operation |
| Drilling | Helps shut in the well during kicks and supports surface BOP stack control |
| Workover | Helps manage pressure while crews run or pull tubing, tools and completion parts |
| Well Testing | Supports temporary pressure control packages and wellbore isolation |
| Completion | Helps maintain a controlled barrier during completion string and tubing operations |
| Wellhead Service | Supports casing head work, tubing head operations and field-site pressure control |
| Replacement Projects | Helps match existing stack height, connection dimensions and ram requirements |
Single Ram BOP vs Double Ram BOP
A Single Ram BOP has one ram cavity. It suits a stack that needs one dedicated function, such as pipe sealing, blind sealing or shearing. It also helps reduce stack height and simplify maintenance.
A Double Ram BOP has two ram cavities in one body. It suits a stack that needs two ram functions, such as pipe ram plus blind ram, pipe ram plus shear ram, or two different pipe ram sizes.
| Comparison Item | Single Ram BOP | Double Ram BOP |
| Ram Cavity | One ram cavity | Two ram cavities |
| Main Purpose | One dedicated ram function | Two ram functions in one body |
| Stack Height | Lower and more compact | Higher than single ram design |
| Maintenance Access | Easier access for one ram set | More parts to inspect and maintain |
| Typical Use | Workover, testing, replacement or one-function barrier | Drilling stack with multiple ram functions |
| Cost Direction | Usually more economical for one function | Higher cost but more functions |
For compact workover stacks, well testing packages and replacement projects, buyers often choose a single ram BOP when one ram function is enough. For drilling stacks with multiple barriers in one body, buyers may choose a double ram BOP. SGPE can review the stack layout and recommend the right BOP type.
Connection Options
A Single Ram BOP must match the wellhead, drilling spool, adapter spool, casing head or other stack components. Therefore, connection confirmation matters before production.
| Connection Item | What to Confirm | Why It Matters |
| Top Connection | Flange, studded or hub type | Must match the upper BOP stack component |
| Bottom Connection | Flange, studded or hub type | Must match wellhead, casing head or adapter spool |
| Ring Gasket Groove | RX, BX or project-specific groove | Prevents sealing mismatch |
| Bolt / Stud Size | Size, grade and quantity | Supports correct installation |
| Face-to-Face Dimension | Overall stack height requirement | Helps avoid rig-up problems |
| Side Outlet | Size, pressure and connection | Supports choke, kill or auxiliary lines if required |
For replacement projects, SGPE recommends sending the stack drawing or connection sketch. This helps the technical team avoid confusion between flanged, studded, hub and special connections.

How to Select the Right API 16A Single Ram BOP Blowout Preventer
Start with bore size and working pressure. The BOP bore must match the wellhead or stack bore, while the pressure rating must meet the maximum expected well pressure and end-user requirement.
Next, choose the ram type. Pipe rams suit known drill pipe, tubing or casing sizes. Blind rams suit open-bore sealing. Variable bore rams support several tubular sizes. Shear rams suit emergency cutting and sealing requirements after engineering confirmation.
Then, confirm the connection. Top and bottom connections must match the existing stack. Side outlets also need review when the stack requires choke and kill connections or auxiliary pressure control lines.
After that, define the field condition. Sour service, H2S service, low-temperature service or high-temperature service can affect material selection, elastomer selection, testing scope and documentation.
Finally, confirm certificates and inspection documents. Many end users require API 16A compliance documents, MTC, hydrostatic pressure test report, NACE statement, dimensional report, assembly report and operation manual.
