High Pressure Double Ram Blowout Preventer for Oil Wells - China Suppliers and Factory
Product Description
This integrated double ram BOP combines two sets of ram units inside a single high-strength alloy steel body, supporting customizable combinations of pipe ram, blind ram and shear ram to meet diverse well control demands. Controlled by remote hydraulic power unit, it features mechanical locking structure to sustain sealing under loss of hydraulic pressure. The internal cavity adopts supersonic anti-corrosion spraying to resist H2S and seawater erosion. It can be stacked with annular BOP, casing head and choke manifold to form a complete well control stack, applicable for high-pressure deep wells, sulfur-containing wells and marine drilling platforms. All products pass API 16A full performance test, optional PR2 grade for heavy-cycle harsh working conditions.
Product Features
- Dual ram integrated design, two sealing functions in one unit, saving wellhead space and reducing matching cost.

Frequently Asked Questions
What configurations are available for the Double Ram BOP?
The Double Ram BOP supports customizable combinations of two ram units, including Pipe Ram, Blind Ram, Shear Ram, and Blind Shear Ram, allowing operators to match specific well control requirements.
Is this blowout preventer certified to international standards?
Yes, all our blowout preventers are fully compliant with API Spec 16A standards and undergo full performance testing. An optional PR2 performance level is also available for heavy-cycle, harsh working environments.
How does the BOP maintain its seal if hydraulic pressure fails?
The unit is engineered with a manual mechanical locking structure as a backup. This ensures that the ram units sustain their sealing integrity even in the event of a total loss of remote hydraulic pressure.
What materials are used to prevent corrosion in offshore or sour gas environments?
The shell is constructed from high-strength forged alloy steel (42CrMo/4130). Additionally, the internal cavity utilizes supersonic anti-corrosion spraying to protect the equipment against H2S, brine, crude oil, and seawater erosion.
What are the available working pressure ratings and bore sizes?
We offer a full range of standard API pressure classes, including 2000psi, 3000psi, 5000psi, 10000psi, and 15000psi. Available nominal bore sizes include 7 1/16”, 9”, 11”, 13 5/8”, and 18 3/4”.
Can this BOP be integrated into existing well control stacks?
Yes, featuring flanged, studded, or clamp hub connections, it is fully compatible with API standard wellhead equipment and can be seamlessly stacked with annular BOPs, casing heads, and choke manifolds.
