Subsurface Safety Valve Equipment (SSSV)

Qualification Testing of Subsurface Safety Valve Equipment to API 14A

The Industry Challenge

Operators are completing wells in increasingly challenging environments where equipment are subject to extreme pressures, temperatures, and mechanical loading. It is critical to ensure that equipment can withstand these conditions through validation testing.

API Specification 14A (2015) Annex J provides a methodology by which manufacturers/end users may verify that the SSSV hydro mechanical system functions properly at all anticipated in service loading conditions (the Rated Performance Envelope).

Annex H of the standard (Verification and Validation Requirements for High-pressure, High-temperature Environment) requires performance of the Combined Loads Operational Test at maximum rated operating temperature, i.e. 350°F (176.7°C) and higher.
