Flow API Valve Standards

This specification provides the requirements for subsurface safety valves (SSSVs), and the secondary tools as defined herein necessary to operate the features included within them, including all components that establish tolerances and/or clearances that may affect performance or...

ABSTRACT This report presents the findings and recommendations from the second year of an American Petroleum Institute (API) research study aimed at updating the API Specification 14A Verification Test Procedure for surface-controlled subsurface safety valves (SCSSV)....

SCOPE & LIMITATIONS Selection of a leakage class is not restricted as to valve design, but acceptable values for various commercially available designs are suggested for each class under Section 4. This standard applies to control valve seat leak production testing and cannot be used...

ABSTRACT This report presents the findings and recommendations from the third year of an American Petroleum Institute (API) research study aimed at updating the Specification 14A Verification Test Procedure for surface-controlled subsurface safety valves (SCSSV). Specification 14A was...

This Recommended Practice (RP) provides general guidance on valve selection for the hydrocarbon processing industry (HPI), which includes refineries and petrochemical, chemical, and liquefied natural gas (LNG) plants and their various associated processes. Selection guidance is provided for...

This recommended practice (RP) provides recommendations for evaluation of a manufacturer's valve construction and quality management system for the purpose of determining a manufacturer's capability to provide new valves manufactured in accordance with the applicable standards listed...

This standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated (e.g. ceramic), and metal-to-metal-seated valves of the gate, globe, plug, ball, check, and butterfly types. Resilient seats are considered to be:...

Test site recommendations (Section 3): This section outlines the equipment needed for testing valves to determine the following: a. Valve flow coefficients (Cv). b. Pressure drop ratio factor (Xt). c. Gas-lift valve performance curves. Gas-lift valve probe tests...

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...

Recommended Practice 11V7 applies to repair, testing, and setting gas lift valves and reverse flow (check) valves. This is a recommended practice to present guidelines related to the repair and reuse of valves; these practices are intended to serve both repair shops and...

1. INTRODUCTION Subsurface safety valves (SSSVs) are required by law in most offshore producing wells. The purpose of the valves is to shut off well flow in the production tubing below the mudline in the event disasters, such as explosions or fires, disable surface shutdown...

This Recommended Practice is intended to set guidelines for continuous flow gas lift installation designs using injection pressure operated valves. The assumption is made that the designer is familiar with and has available data on the various factors that affect a design. The...

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...

This document addresses recommendations for subsea structures and manifolds, within the frameworks set forth by recognized and accepted industry specifications and standards. Equipment within the scope of this document is listed below (see Figure 1): a) the following structural components and...
