High Pressure Double Ram Blowout Preventer for Oil Wells
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
- Integral forged alloy steel body, no casting defects, strong pressure and impact resistance
- Hydraulic fast opening-closing with mechanical lock, stable sealing even when hydraulic power fails
- Modular replaceable ram core and sealing rubber, convenient on-site maintenance, less downtime
- Anti-corrosion inner coating, resistant to hydrogen sulfide, brine and crude oil corrosion
- Multiple bore and pressure options, highly compatible with full API standard well control equipment
- Optional shear ram for emergency pipe cutting and full well shutoff to eliminate blowout risks
- API 16A certified, globally recognized for oilfield export project procurement
