Production acceptance and type (or qualification) tests. Applicable to 2-, 3- and 4-way flow control valves and to 2-way pressure control valves.

API REPORT OSAPR 1 - Orifice Coefficients for Two-Phase Flow Through Velocity Controlled Subsurface Safety Valves
September 1, 1976 - API

1. INTRODUCTION Subsurface safety valves (SSSVs) are required by law in most offshore producing wells and are one of many devices available for well fluid containment. The purpose of the valves is to shut off well flow in the production tubing below the mudline in the event...

ISA 75.17 - Control Valve Aerodynamic Noise Prediction
January 1, 1989 - ISA

This standard establishes a method to predict the noise generated in a control valve of standard design by the flow of compressible fluid and the resulting noise outside of the pipe and downstream of the valve. The transmission loss (TL) equations are based on a rigorous...
