Specification for Subsurface Safety Valve Equipment
|Publication Date:||1 November 2000|
This International Standard provides the minimum acceptable requirements for subsurface safety valves (SSSVs). It covers subsurface safety valves including all components that establish tolerances and/or clearances which may affect performance or interchangeability of the SSSVs. It includes repair operations and the interface connections to the flow control or other equipment, but does not cover the connections to the well conduit.
Limits: The subsurface safety valve is an emergency safety device, and
is not intended or designed
for operational activities, such as production/injection
Redress activities are beyond the scope of this International Standard, see Clause 8.
