SL Type Annular BOP

Parameters

The SL Type Annular Blowout Preventer (BOP) is engineered to deliver absolute pressure control during critical wellbore operations. The exact technical specifications outlined below demonstrate its capacity to handle demanding drilling environments. With a heavy-duty studded top connection and a secure flanged bottom connection, this equipment ensures safe integration into your existing wellhead stack. The hydraulic system is meticulously calibrated, requiring 18.9 gallons to open and 31.1 gallons to close, guaranteeing swift response times when securing the well. Weighing 7,000 kilograms and featuring an overall dimension of Ø1392 x 1341 mm, the structural integrity of this BOP is built to withstand extreme mechanical stress while maintaining a reliable seal under 2,000 psi working pressure.

Reference to Standards

Compliance with globally recognized engineering standards is non-negotiable for well control equipment. Our SL Type Annular BOP is manufactured and rigorously tested in strict accordance with the latest American Petroleum Institute (API) and NACE specifications. Adhering to API Spec 16A (4th edition) ensures the core drill-through equipment meets the highest safety criteria, while API Spec 6A (21st edition) guarantees proper wellhead and tree equipment compatibility. Furthermore, the incorporation of API Spec 20E (3rd edition) for alloy and carbon steel bolting provides exceptional mechanical fastening strength. For operations in sour gas fields, strict compliance with NACE MR0175-2021 ensures the metallic and non-metallic components resist hydrogen sulfide cracking, safeguarding your personnel and assets during prolonged exposure to corrosive wellbore fluids.

Specifications of the SL-type BOP we can provide

• 20-3/4" 3,000psi

• 21-1/4" 2,000psi

To accommodate varying rig setups and casing programs, we supply the SL-Type Annular BOP in specific dimensional and pressure configurations. These models are tailored to provide maximum versatility without compromising on structural rigidity or sealing effectiveness. Whether your drilling program requires the 20-3/4 inch bore diameter for larger casing strings or the 21-1/4 inch variant for specialized well control stacks, each unit delivers consistent performance. The heavy-duty steel housing and precision-machined internal profiles ensure that these specific configurations integrate efficiently into your blowout preventer stack, providing operators with the exact dimensional tolerances required for safe, uninterrupted drilling operations.
