China API 16A Annular Blowout Preventer BOP Suppliers, Reliable Factory for Onshore & Offshore Applications
Key Capabilities
Engineering Advantages
Enhanced Reliability
Features a self-sealing lip seal design that minimizes leak risks, even under fluctuating pressures. A dedicated bore in the piston allows for stroke testing, enabling proactive monitoring of sealing element life—reducing unplanned downtime.
Durability
Friction surfaces are protected by replaceable abrasion-resistant plates, safeguarding the main housing and simplifying maintenance.
Long-Lasting Sealing
The packing element is engineered with high rubber storage capacity, reducing friction during pressure cycling and extending service life. It maintains positive sealing even after hundreds of full-pressure tests.
Simplified Maintenance
With only five major components, the design streamlines disassembly and repair. Hemispherical housing ends eliminate stress concentration under pressure, making inspection and part replacement faster and safer.
