Integrity HPHT subsurface safety valve
Engineered, tested, and qualified to function effectively even at extremely high pressures and temperatures
These valves are set at shallow depths in HPHT oil and gas wells.
Preserve the integrity of your well
Integrity HPHT safety valves serve as the ultimate defense in the complex process of HPHT oil and gas production, safeguarding operations and personnel in the event of compromised well integrity.
The valves have a robust design, with patented seal technology and resilient materials that are specifically chosen for their durability—a critical factor given the potential impact of HPHT conditions on long-term valve integrity. Rigorous testing and qualification processes ensure valve performance at extreme temperatures and pressures, especially during emergency closures.
The valve actuator incorporates multizone seal technology to provide a dynamic seal solution that surpasses traditional seal systems in reliability. Designed for high performance and longevity, the actuator requires hydraulic pressure for operation, which simplifies control system requirements. This combination of advanced technology and thoughtful design ensures the effectiveness and dependability of Integrity HPHT safety valves.
How are the valves qualified?
The valves are validated to API Spec 14A V1, but their performance exceeds the certification requirements.
Flapper leakage: API Spec 14A allows leakage up to 5 ft3/min. The acceptance criterion for Integrity HPHT safety valve flapper systems is bubble-tight performance.
Hydraulic actuator integrity: API Spec 14A allows up to 5% drop in applied hydraulic pressure; for 10,000-psi hydraulic pressure, the acceptable leakage is 500 psi. Integrity HPHT safety valve actuators allow <1% drop, as confirmed by rigorous tests.
Slam closure: The valve's flapper system has been successfully slam tested at high flow rates that exceed the Annex K requirements of API Spec 14A.
