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-seate
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 (Section...
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 specification is applicable to all valve springs, ready for installation, which are manufactured from alloy spring steel. Mission / Theme. Not applicable. Classification. Not applicable. Note: Nothing in the specification, however, supersedes applicable laws and regulations unless a...
This standard specifies the requirements for comparative testing of valve stem packing for process applications where fugitive emissions are a consideration. Packing(s) shall be suitable for use at service temperatures -29 °C to 538 °C (-20 °F to 1000 °F). Factors affecting fugitive...
ABSTRACT This report presents the findings of a study for the Production Department of the American Petroleum Institute entitled, "Subsurface Safety Valve Research Study--Year 1". The purpose of the work is to define potential changes to API Specification 14A for Subsurface Safety...
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...
1 Scope 1.1 This standard covers the requirements for testing and evaluating the performance of valve stem packing when it is exposed to a fire as defined in this standard. Packing may be a combination or an arrangement of more than one material. The test procedure in this standard simulates...
1.1 Project Scope This report summarizes the findings and recommendations from a four year research study aimed at updating the American Petroleum Institute (AFT) Specification 14A Verification Test Procedures for surface-controlled subsurface safety valves (SCSSVs) and subsurface-controlle
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 devices....
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)....
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...
