Choke API Valve Standards

This specification identifies requirements for the performance, design, materials, testing, inspection, welding, marking, handling, storing, shipment, and purchasing of surface and subsea choke and kill equipment for use in the petroleum and natural gas industries. These requirements provide...

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...

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...

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 disasters,...

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:...

Coverage. This specification covers items of equipment utilized for pressure control systems required during the drilling and production life of a well. Specifically covered are the groups of equipment usually referred to as ring-joint flange., ring joint gaskets, drilling-through and flow line...

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....

This drawing describes the requirements for a family of radiofrequency coils and radiofrequency chokes. The chokes consist of rod-type ferrite bodies with axial holes through which wire is threaded to form 1.50 or 2.50 turn radiofrequency coils. The radiofrequency coils are the...

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....

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...

1. SCOPE This specification establishes the performance and product requirements for an automotive automatic choke and carburetor linkage cleaner.

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...

SCOPE 101. PURPOSE. This recommended practice was formulated to provide guidelines for the repair and remanufacture of safe, interchangeable wellhead and Christmas tree equipment. Technical content provides recommendations for performance, design, materials, testing, inspection, welding, marking,...

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...
