Oct 13, 2009 - It is our pleasure to announce that API 609, Standard for Butterfly Valves: Double. Flanged, Lug- and Wafer type, Seventh Edition has been published. This Document is not presently a co- branded ISO Standard. The publication date for this document is October 2009 with an effective implementation date. What is the significance of API 608 compliance for valves? This standard has been developed by the API in 1989 as the standard to be used by “downstream. Hi, API 609 related to Butterfly Valves is divided in 2 categories: A & B. Wow Astro Calendar Serial Killers. One of the piping classes on my project is giving me the choice between both, for al.
Valve standards from: • API SPEC 6D Specification for Pipeline Valves. Microsoft Access 2010 Sql Reference Constraint. API Specification 6D is an adoption of 14313: 1999, Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems.
• API 526 Flanged Steel Pressure Relief Valves. The standard is a purchase specification for flanged steel pressure relief valves. Basic requirements are given for direct spring-loaded pressure relief valves and pilot-operated pressure relief valves as follows: orifice designation and area; valve size and pressure rating, inlet and outlet; materials; pressure-temperature limits; and center-to-face dimensions, inlet and outlet. • API 527 Seat Tightness of Pressure Relief Valves R(2002).
Describes methods of determining the seat tightness of metal- and soft-seated pressure relief valves, including those of conventional, bellows, and pilot-operated designs. • ANSI/API STD 594 Check Valves: Flanged, Lug, Wafer and Butt-welding. API Standard 594 covers design, material, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for two types of check valves. • API 598 Valve Inspection and Testing. The standard covers inspection, supplementary examination, and pressure test requirements for both resilient-seated and metal-to-metal seated gate, globe, plug, ball, check, and butterfly valves. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant.
• ANSI/API 599 Metal Plug Valves - Flanged, Threaded and Welding Ends. A purchase specification that covers requirements for metal plug valves with flanged or butt-welding ends, and ductile iron plug valves with flanged ends, in sizes NPS 1 through NPS 24, which correspond to nominal pipe sizes in B36.10M.
Valve bodies conforming to B16.34 may have flanged end and one butt-welding end. It also covers both lubricated and nonlubricated valves that have two-way coaxial ports, and includes requirements for valves fitted with internal body, plug, or port linings or applied hard facings on the body, body ports, plug, or plug port. • ANSI/API 600 Bolted Bonnet Steel Gate Valves for Petroleum and Natural Gas Industries - Modified National Adoption of ISO. • API 602 Compact Steel Gate Valves - Flanged, Threaded, Welding, and Extended-Body Ends. The standard covers threaded-end, socket-welding-end, butt-welding-end, and flanged-end compact carbon steel gate valves in sizes NPS4 and smaller. • ANSI/API 603 Corrosion-Resistant, Bolted Bonnet Gate Valves - Flanged and Butt-Welding Ends.
The standard covers corrosion-resistant bolted bonnet gate valves with flanged or butt-weld ends in sizes NPS 1/2 through 24, corresponding to nominal pipe sizes in B36.10M, and Classes 150, 300, and, 600, as specified in B16.34. • ANSI/API 607 Fire Test for Soft-Seated Quarter Turn Valves. The standard covers the requirements for testing and evaluating the performance of straightway, soft-seated quarter-turn valves when the valves are exposed to certain fire conditions defined in this standard. The procedures described in this standard apply to all classes and sizes of such valves that are made of materials listed in ASME B16.34. • API 609 Butterfly Valves: Double Flanged, Lug- and Wafer-Type. The standard covers design, materials, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for gray iron, ductile iron, bronze, steel, nickel-base alloy, or special alloy butterfly valves that provide tight shutoff in the closed position and are suitable for flow regulation. • API 6FA Specification for Fire Test for Valves.
