API Surface Safety Valve & ESD For Surface Well Testing Service

The Surface Safety Valve is an important equipment for surface well testing. Since the consequences of uncontrolled flow are so severe,especially offshore,well safety saystems are important enough that they are sometimes mandated by law.Safety systems must be failsafe.Failure of the energy source or any component must cause the system to shut in the well at one or more points.

Safety systems sense conditions and shut in the well or wells when conditions deviate from the preset limits.Shutting in the well averts further danger due to:

1.Uncontrolled flow from ruptured pressure vessel.

2.Fueling any fire that has started or may start.

3.Overfilling vessels with fluid and/or pressure.

The surface safety valves(SSV) are operated by Emergency shutdown(ESD) system.The ESD system enables field operators to shut down the upstream flow at any desired location during production testing operation.Shut down is achieved by transmitting pressure either by hydraulic or pneumatic medium to the SSV actuator.
