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...
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
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 standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated (e.g. ceramic), and metal-to-metal-seate
It is the purpose of this document to establish the requirements for testing and evaluating the pressure containing performance of valves when exposed to fire. The performance requirements of this document are intended to establish standard limits of acceptability regardless of size or...
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...
This User's Manual describes the use of the API sponsored computer program API14B for SSCSV sizing. This program is not represented as the exclusive method of sizing SSCSVs; however, it is a method recommended by the API and is based on published or industry accepted assumptions,...
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 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...
According to the Request for Proposal API 11V2 Verification Test #1 by Mr. Kenneth L. Decker, Chairman of the API 11V2 Work Group, the purpose of this test is to note the ability to determine if the Test Site Recommendations can be verified, rather to verify that the system complies...
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 recommended practice provides guidelines for the repair and remanufacture of steel ball, check, gate, and plug valves normally used in pipeline applications, as defined by API 6D. This recommended practice covers repair or remanufacturing of end user's (owner's) valves for...
This standard covers ductile iron gate valves with flanged ends, in sizes NPS 1 ½ through 24, corresponding to nominal pipe sizes in ANSI B36.10. This standard covers valves in Classes 150 and 300, as specified in ANSI B16.42. The vales covered are the outside screw-and-yoke (OS&Y)...
This standard defines the requirements for design, mechanical integrity, and sizing of actuators and related components, and is applicable to all types of electric, pneumatic, and hydraulic actuators, inclusive of mounting kit, installed on valves that conform to API Specification 6D....
This standard establishes the requirements for testing and evaluating the pressure-containing performance of API 6A and API 6D valves when exposed to fire. The performance requirements of this standard establish qualification criteria for all sizes and pressure ratings. This...
There are three service classes, Class I, Class II, and Class III, for API 6A surface safety valve (SSV), underwater safety valve (USV), or boarding shutdown valve (BSDV). This standard establishes sandy service design validation for valves to meet Class II and...
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...
General This specification defines the requirements for the design, manufacturing, assembly, testing, and documentation of ball, check, gate, and plug valves for application in pipeline and piping systems for the petroleum and natural gas industries. This specification is not applicable to...
This recommended practice (RP) provides guidelines for reconditioning heavy wall (API 600, API 623, and API 594 type) carbon steel, ferritic alloy (up to 9 % Cr), stainless steel, and nickel alloy gate, globe, and check valves for ASME pressure classes 150, 300, 400,...
