API 6D exceeds API 598 in both pressure and duration.
Both deal with valves. API6FA is for API 6A and 6D. API607 applies to soft-seated, quarter-turn valves.
API 6D is a specification developed by the American Petroleum Institute that outlines the requirements for pipeline and piping valves used in the oil and gas industry. It encompasses design, manufacturing, testing, and performance standards for various types of valves, including gate, ball, check, and plug valves. Compliance with API 6D ensures that these valves can operate safely and reliably under specified conditions, contributing to the overall integrity of pipeline systems.
= BS EN ISO 17292:2004 = it is better to use ISO 14313 2007 edition as most practical and coverage for Pipeline valves
API 6D does not specifically mandate a full bore opening for all valves; however, it does specify that ball and gate valves should provide a full bore option to facilitate pipeline cleaning and maintenance. The standard emphasizes the importance of flow characteristics and pressure drop, which are often best achieved with full bore designs. Ultimately, the choice of valve type and design may depend on the application and system requirements.
In the context of bend pipes, "6D" refers to the bend radius being six times the nominal diameter of the pipe. For example, if the pipe has a diameter of 2 inches, a 6D bend would have a radius of 12 inches. This specification is important for ensuring smooth flow and reducing turbulence in piping systems. It is commonly used in various engineering applications to maintain structural integrity and optimize fluid dynamics.
The pressure test for API 598 is slightly less pressure and less duration than API 6D. API 6D is specifically for pipeline valves.
It's quite easy. API 6A speaks about wellhead and x-mas tree equipment, API 6D speaks about pipeline valves. If you are phisically looking to one valve, you can also understand if it belows to 6A or 6D giving a look to the valve label. On the label you can read the class of the valve. If the class is 2000 or 3000 or 5000 or 10000 or 15000 or 20000 the valve is 6A. If the class is 125 or 150 or 300 or 400 or 600 or 900 or 1500 or 2500 the valve probably is a 6D ("probably" because the same classes of API 6D are used also by other API standards, like 594, 600, 608, ecc ecc).
Both deal with valves. API6FA is for API 6A and 6D. API607 applies to soft-seated, quarter-turn valves.
Valve standards from API - the American Petroleum Institute: * API SPEC 6D Specification for Pipeline Valves. API Specification 6D is an adoption of ISO 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. * ANSI/API 600 Bolted Bonnet Steel Gate Valves for Petroleum and Natural Gas Industries - Modified National Adoption of ISO 10434:1998.

If -6d = 42 then 6d = -42. then divide by 6, d = -7
-6d = -42-6(7) = -42d = 7
72-6d=6 subtract 72 from both sides -6d=66 divide by -6 d=-11
yes you can
