surface safety valve

ApplicAtions ■ Testing oil and gas wells with high flow rates, high wellhead pressures, or the presence of H 2 S ■ Wells with hazard operational analysis needing a surface pressure barrier in addition to the primary or master valve Benefits ■ Prevent overpressure conditions on downstream equipment ■ Provide immediate well closure in the event of downstream equipment failure ■ Ensure reliable shut-in during harsh environment operations ■ Reduce personnel exposure in emergencies ■ Comply with environmental regulations and reduce environmental risk feAtures ■ Fail-safe remote activation and auto- matic well closure when loss of control pressure occurs ■ Double metal-to-metal seals for reliability in harsh environments ■ Normally equipped with hammer unions, but can be fitted with Grayloc or API-6A flanges ■ Compliance with API-6A PSL-2 or 3, PR2, H 2 S NACE MR0175, and Fluid Class DD specifications The surface safety valve SSV is a hydraulically actuated fail-safe gate valve for testing oil and gas wells with high flow rates 8,000 bbl/d [1,280 m 3 /d] or 30,000,000 ft 3 /d [850,000 m 3 /d], high pressures 5,000 psi [34 MPa], or the presence of H 2 S. The SSV is used to quickly shut in the well choke manifold upstream in the event of overpressure, failure, a leak in downstream equipment, or any other well emergency requiring an immediate shut-in. The SSV is remotely operated by an emergency shutdown device ESD, which can be triggered automatically by high- or low-pressure pilot actuators. If an emergency occurs, this feature reduces the possibility of personnel injuries. A number of SSV models are available for different well conditions pressures, temperatures, and flow rates and with various connections, such as Grayloc or API-6A flanges. All SSV models have interchangeable crossover connections and are protected by a compact, removable lifting frame. The SSV uses a proven metal-to-metal, double-sealing design for harsh environment operations and complies with all applicable environmental requirements. All SSVs are manufactured under Type Approval or Design Verification Review and provided with a Certificate of Conformity and full quality file.
